THE CYPHERNOMICON 1. Introduction 1.1. copyright THE CYPHERNOMICON: Cypherpunks FAQ and More, Version 0.666, 1994-09-10, Copyright Timothy C. May. All rights reserved. See the detailed disclaimer. Use short sections under "fair use" provisions, with appropriate credit, but don't put your name on my words. 1.2. Foreword - The Cypherpunks have existed since September, 1992. In that time, a vast amount has been written on cryptography, key escrow, Clipper, the Net, the Information Superhighway, cyber terrorists, and crypto anarchy. We have found ourselves (or _placed_ ourselves) at the center of the storm. - This FAQ may help to fill in some gaps about what we're about, what motivates us, and where we're going. And maybe some useful knowledge on crypto, remailers, anonymity, digital cash, and other interesting things. + The Basic Issues + Great Divide: privacy vs. compliance with laws + free speech and privacy, even if means some criminals cannot be caught (a stand the U.S. Constitution was strongly in favor of, at one time) - a man's home is his castle...the essence of the Magna Carta systems...rights of the individual to be secure from random searches + or invasive tactics to catch criminals, regulate behavior, and control the population - the legitimate needs to enforce laws, to respond to situations + this parallels the issue of self-protection vs. protection by law and police - as seen in the gun debate - crypto = guns in the sense of being an individual's preemptive protection - past the point of no return - Strong crypto as building material for a new age + Transnationalism and Increased Degrees of Freedom - governments can't hope to control movements and communications of citizens; borders are transparent + Not all list members share all views - This is not "the Official Cypherpunks FAQ." No such thing can exist. This is the FAQ I wanted written. Views expressed are my own, with as much input from others, as much consensus, as I can manage. If you want a radically different FAQ, write it yourself. If you don't like this FAQ, don't read it. And tell your friends not to read it. But don't bog down my mailbox, or the 500 others on the list, with messages about how you would have worded Section 12.4.7.2 slightly differently, or how Section 6.9.12 does not fully reflect your views. For obvious reasons. - All FAQs are the products of a primary author, sometimes of a committee. For this FAQ, I am the sole author. At least of the version you are reading now. Future versions may have more input from others, though this makes me nervous (I favor new authors writing their own stuff, or using hypertext links, rather than taking my basic writing and attaching their name to it--it is true that I include the quotes of many folks here, but I do so by explicitly quoting them in the chunk they wrote....it will be tough for later authors to clearly mark what Tim May wrote without excessively cluttering the text. The revisionist's dilemma. - The list has a lot of radical libertarians, some anarcho- capitalists, and even a few socialists - Mostly computer-related folks, as might be expected. (There are some political scientists, classical scholars, etc. Even a few current or ex-lawyers.) + Do I Speak for Others? - As I said, no. But sometimes I make claims about what "most" list members believe, what "many" believe, or what "some" believe. - "Most" is my best judgment of what the majority believe, at least the vocal majority in Cypherpunks discussions (at the physical meetings, parties, etc.) and on the List. "Many" means fewer, and "some" fewer still. "A few" will mean a distinct minority. Note that this is from the last 18 months of activity (so don't send in clarifications now to try to "sway the vote"). - In particular, some members may be quite uncomfortable being described as anarchists, crypto anarchists, money launderers, etc. + My comments won't please everyone - on nearly every point ever presented, some have disagreed - feuds, battles, flames, idee fixes - on issues ranging from gun control to Dolphin Encrypt to various pet theories held dearly - Someone once made a mundane joke about pseudonyms being like multiple personality disorder--and a flame came back saying: "That's not funny. I am MPD and my SO is MPD. Please stop immediately!" - can't be helped....can't present all sides to all arguments + Focus of this FAQ is U.S.-centric, for various reasons - most on list are in U.S., and I am in U.S. - NSA and crypto community is largely centered in the U.S., with some strong European activities - U.S. law is likely to influence overseas law + We are at a fork in the road, a Great Divide - Surveillance vs. Freedom - nothing in the middle...either strong crypto and privacy is strongly limited, or the things I describe here will be done by some people....hence the "tipping factor" applies (point of no return, horses out of the barn) + I make no claim to speaking "for the group." If you're offended, write your own FAQ. My focus on things loosely called "crypto anarchy" is just that: my _focus_. This focus naturally percolates over into something like this FAQ, just as someone primarily interested in the mechanics of PGP would devote more space to PGP issues than I have. - Gary Jeffers, for example, devotes most of his "CEB" to issues surrounding PGP. + Will leave out some of the highly detailed items... - Clipper, LEAF, escrow, Denning, etc. - a myriad of encryption programs, bulk ciphers, variants on PGP, etc. Some of these I've listed...others I've had to throw my hands over and just ignore. (Keeping track of zillions of versions for dozens of platforms...) - easy to get lost in the details, buried in the bullshit 1.3. Motivations 1.3.1. With so much material available, why another FAQ? 1.3.2. No convenient access to archives of the list....and who could read 50 MB of stuff anyway? 1.3.3. Why not Web? (Mosaic, Http, URL, etc.) - Why not a navigable Web document? - This is becoming trendy. Lots of URLs are included here, in fact. But making all documents into Web documents has downsides. + Reasons why not: - No easy access for me. - Many others also lack access. Text still rules. - Not at all clear that a collection of hundreds of fragments is useful - I like the structured editors available on my Mac (specifically, MORE, an outline editor) - 1.3.4. What the Essential Points Are - It's easy to lose track of what the core issues are, what the really important points are. In a FAQ like this, a vast amount of "cruft" is presented, that is, a vast amount of miscellaneous, tangential, and epiphenomenal material. Names of PGP versions, variants on steganograhy, and other such stuff, all of which will change over the next few months and years. + And yet that's partly what a FAQ is for. The key is just not to lose track of the key ideas. I've mentioned what I think are the important ideas many times. To wit: - that many approaches to crypto exist - that governments essentially cannot stop most of these approaches, short of establishing a police state (and probably not even then) - core issues of identity, authentication, pseudonyms, reputations, etc. 1.4. Who Should Read This 1.4.1. "Should I read this?" - Yes, reading this will point you toward other sources of information, will answer the most commonly asked questions, and will (hopefully) head off the reappearance of the same tired themes every few months. - Use a search tool if you have one. Grep for the things that interest you, etc. The granularity of this FAQ does not lend itself to Web conversion, at least not with present tools. + What _Won't_ Be Covered Here + basic cryptography + many good texts, FAQs, etc., written by full-time cryptologists and educators - in particular, some of the ideas are not simple, and take several pages of well-written text to get the point across - not the focus of this FAQ - basic political rants 1.5. Comments on Style and Thoroughness 1.5.1. "Why is this FAQ not in Mosaic form?" - because the author (tcmay, as of 7/94) does not have Mosaic access, and even if did, would not necessarily.... - linear text is still fine for some things...can be read on all platforms, can be printed out, and can be searched with standard grep and similar tools 1.5.2. "Why the mix of styles?" + There are three main types of styles here: - Standard prose sections, explaining some point or listing things. Mini-essays, like most posts to Cypherpunks. + Short, outline-style comments - that I didn't have time or willpower to expand into prose format - that work best in outline format anyway - like this + Quotes from others - Cypherpunks are a bright group. A lot of clever things have been said in the 600 days x 40 posts/day = 24,000 posts, and I am trying to use what I can. + Sadly, only a tiny fraction can be used - because I simply cannot _read_ even a fraction of these posts over again (though I've only saved several thousand of the posts) - and because including too many of these posts would simply make the FAQ too long (it's still too long, I suppose) - I hope you can handle the changes in tone of voice, in styles, and even in formats. It'll just too much time to make it all read uniformly. 1.5.3. Despite the length of this thing, a vast amount of stuff is missing. There have been hundreds of incisive analyses by Cypherpunks, dozens of survey articles on Clipper, and thousands of clever remarks. Alas, only a few of them here. - And with 25 or more books on the Internet, hundreds of FAQs and URLs, it's clear that we're all drowning in a sea of information about the Net. - Ironically, good old-fashioned books have a lot more relevant and timeless information. 1.5.4. Caveats on the completeness or accuracy of this FAQ + not all points are fully fleshed out...the outline nature means that nearly all points could be further added-to, subdivided, taxonomized, and generally fleshed-out with more points, counterpoints, examples - like a giant tree...branches, leaves, tangled hierarchies + It is inevitable that conflicting points will be made in a document of this size - views change, but don't get corrected in all places - different contexts lead to different viewpoints - simple failure by me to be fully consistent - and many points raised here would, if put into an essay for the Cypherpunks list, generate comments, rebuttals, debate, and even acrimony....I cannot expect to have all sides represented fully, especially as the issues are often murky, unresolved, in dispute, and generally controversial - inconsistencies in the points here in this FAQ 1.6. Corrections and Elaborations + "How to handle corrections or clarifications?" - While I have done my best to ensure accuracy, errors will no doubt exist. And as anyone can see from reading the Cypherpunks list, nearly *any* statement made about any subject can produce a flurry of rebuttals, caveats, expansions, and whatnot. Some subjects, such as the nature of money, the role of Cypherpunks, and the role of reputations, produce dozens of differing opinions every time they come up! - So, it is not likely that my points here will be any different. Fortunately, the sheer number of points here means that not every one of them will be disagreed with. But the math is pretty clear: if every reader finds even one thing to disagree with and then posts his rebuttal or elaboration....disaster! (Especially if some people can't trim quotes properly and end up including a big chunk of text.) + Recommendations - Send corrections of _fact_ to me - If you disagree with my opinion, and you think you can change my mind, or cause me to include your opinion as an elaboration or as a dissenting view, then send it. If your point requires long debate or is a deep disagreement, then I doubt I have the time or energy to debate. If you want your views heard, write your own FAQ! - Ultimately, send what you want. But I of course will evaluate comments and apply a reputation-based filter to the traffic. Those who send me concise, well-reasoned corrections or clarifications are likelier to be listened to than those who barrage me with minor clarifications and elaborations. - In short, this is not a group project. The "stone soup FAQ" is not what this is. + More information - Please don't send me e-mail asking for more information on a particular topic--I just can't handle custom research. This FAQ is long enough, and the Glossary at the end contains additional information, so that I cannot expand upon these topics (unless there is a general debate on the list). In other words, don't assume this FAQ is an entry point into a larger data base I will generate. I hate to sound so blunt, but I've seen the requests that come in every time I write a fairly long article. + Tips on feedback - Comments about writing style, of the form "I would have written it _this_ way," are especially unwelcome. + Credit issues - inevitable that omissions or collisions will occur - ideas have many fathers - some ideas have been "in the air" for many years + slogans are especially problematic - "They can have my...."...I credit Barlow with this, but I've heard others use it independently (I think; at least I used it before hearing Barlow used it) - "If crypto is outlawed, only outlaws will have crypto" - "Big Brother Inside" - if something really bothers you, send me a note 1.7.

MFAQ--Most Frequently Asked Questions 2.1. copyright THE CYPHERNOMICON: Cypherpunks FAQ and More, Version 0.666, 1994-09-10, Copyright Timothy C. May. All rights reserved. See the detailed disclaimer. Use short sections under "fair use" provisions, with appropriate credit, but don't put your name on my words. 2.2. SUMMARY: MFAQ--Most Frequently Asked Questions 2.2.1. Main Points - These are the main questions that keep coming up. Not necessarily the most basic question, just the ones that get asked a lot. What most FAQs are. 2.2.2. Connections to Other Sections 2.2.3. Where to Find Additional Information - newcomers to crypto should buy Bruce Schneier's "Applied Cryptography"...it will save many hours worth of unnecessary questions and clueless remarks about cryptography. - the various FAQs publishe in the newsroups (like sci.crypt, alt.security.pgp) are very helpful. (also at rtfm.mit.edu) 2.2.4. Miscellaneous Comments - I wasn't sure what to include here in the MFAQ--perhaps people can make suggestions of other things to include. - My advice is that if something interests you, use your editing/searching tools to find the same topic in the main section. Usually (but not always) there's more material in the main chapters than here in the MFAQ. 2.3. "What's the 'Big Picture'?" 2.3.1. Strong crypto is here. It is widely available. 2.3.2. It implies many changes in the way the world works. Private channels between parties who have never met and who never will meet are possible. Totally anonymous, unlinkable, untraceable communications and exchanges are possible. 2.3.3. Transactions can only be *voluntary*, since the parties are untraceable and unknown and can withdraw at any time. This has profound implications for the conventional approach of using the threat of force, directed against parties by governments or by others. In particular, threats of force will fail. 2.3.4. What emerges from this is unclear, but I think it will be a form of anarcho-capitalist market system I call "crypto anarchy." (Voluntary communications only, with no third parties butting in.) 2.4. Organizational 2.4.1. "How do I get on--and off--the Cypherpunks list?" - Send a message to "cypherpunks-request@toad.com" - Any auto-processed commands? - don't send requests to the list as a whole....this will mark you as "clueless" 2.4.2. "Why does the Cypherpunks list sometimes go down, or lose the subscription list?" - The host machine, toad.com, owned by John Gilmore, has had the usual problems such machines have: overloading, shortages of disk space, software upgrades, etc. Hugh Daniel has done an admirable job of keeping it in good shape, but problems do occur. - Think of it as warning that lists and communication systems remain somewhat fragile....a lesson for what is needed to make digital money more robust and trustable. - There is no paid staff, no hardware budget for improvements. The work done is strictly voluntarily. 2.4.3. "If I've just joined the Cypherpunks list, what should I do?" - Read for a while. Things will become clearer, themes will emerge, and certain questions will be answered. This is good advice for any group or list, and is especially so for a list with 500 or more people on it. (We hit 700+ at one point, then a couple of list outages knocked the number down a bit.) - Read the references mentioned here, if you can. The sci.crypt FAQ should be read. And purchase Bruce Schneier's "Applied Cryptography" the first chance you get. - Join in on things that interest you, but don't make a fool of yourself. Reputations matter, and you may come to regret having come across as a tedious fool in your first weeks on the list. (If you're a tedious fool after the first few weeks, that may just be your nature, of course.) - Avoid ranting and raving on unrelated topics, such as abortion (pro or con), guns (pro or con), etc. The usual topics that usually generate a lot of heat and not much light. (Yes, most of us have strong views on these and other topics, and, yes, we sometimes let our views creep into discussions. There's no denying that certain resonances exist. I'm just urging caution.) 2.4.4. "I'm swamped by the list volume; what can I do?" - This is a natural reaction. Nobody can follow it all; I spend entirely too many hours a day reading the list, and I certainly can't follow it all. Pick areas of expertise and then follow them and ignore the rest. After all, not seeing things on the list can be no worse than not even being subscribed to the list! - Hit the "delete" key quickly - find someone who will digest it for you (Eric Hughes has repeatedly said anyone can retransmit the list this way; Hal Finney has offered an encrypted list) + Better mailers may help. Some people have used mail-to-news systems and then read the list as a local newsgroup, with threads. - I have Eudora, which supports off-line reading and sorting features, but I generally end up reading with an online mail program (elm). - The mailing list may someday be switched over to a newsgroup, a la "alt.cypherpunks." (This may affect some people whose sites do not carry alt groups.) 2.4.5. "It's very easy to get lost in the morass of detail here. Are there any ways to track what's *really* important?" - First, a lot of the stuff posted in the Usenet newsgroups, and on the Cypherpunks list, is peripheral stuff, epiphenomenal cruft that will blow away in the first strong breeze. Grungy details about PGP shells, about RSA encryption speeds, about NSA supercomputers. There's just no reason for people to worry about "weak IDEA keys" when so many more pressing matters exist. (Let the experts worry.) Little of this makes any real difference, just as little of the stuff in daily newspapers is memorable or deserves to be memorable. - Second, "read the sources." Read "1984," "The Shockwave Rider," "Atlas Shrugged," "True Names." Read the Chaum article on making Big Brother obsolete (October 1985, "Communications of the ACM"). - Third, don't lose sight of the core values: privacy, technological solutions over legal solutions, avoiding taxation, bypassing laws, etc. (Not everyone will agree with all of these points.) - Fourth, don't drown in the detail. Pick some areas of interest and follow _them_. You may not need to know the inner workings of DES or all the switches on PGP to make contributions in other areas. (In fact, you surely don't.) 2.4.6. "Who are the Cypherpunks?" - A mix of about 500-700 + Can find out who by sending message to majordomo@toad.com with the message body text "who cypherpunks" (no quotes, of course). - Is this a privacy flaw? Maybe. - Lots of students (they have the time, the Internet accounts). Lots of computer science/programming folks. Lots of libertarians. - quote from Wired article, and from "Whole Earth Review" 2.4.7. "Who runs the Cypherpunks?" - Nobody. There's no formal "leadership." No ruler = no head = an arch = anarchy. (Look up the etymology of anarchy.) - However, the mailing list currently resides on a physical machine, and this machine creates some nexus of control, much like having a party at someon'e house. The list administrator is currently Eric Hughes (and has been since the beginning). He is helped by Hugh Daniel, who often does maintenance of the toad.com, and by John Gilmore, who owns the toad.com machine and account. - In an extreme situation of abuse or neverending ranting, these folks could kick someone off the list and block them from resubscribing via majordomo. (I presume they could-- it's never happened.) - To emphasize: nobody's ever been kicked off the list, so far as I know. Not even Detweiler...he asked to be removed (when the list subscribes were done manually). - As to who sets policy, there is no policy! No charter, no agenda, no action items. Just what people want to work on themselves. Which is all that can be expected. (Some people get frustrated at this lack of consensus, and they sometimes start flaming and ranting about "Cypherpunks never do anything," but this lack of consensus is to be expected. Nobody's being paid, nobody's got hiring and firing authority, so any work that gets done has to be voluntary. Some volunteer groups are more organized than we are, but there are other factors that make this more possible for them than it is for us. C'est la vie.) - Those who get heard on the mailing list, or in the physical meetings, are those who write articles that people find interesting or who say things of note. Sounds fair to me. 2.4.8. "Why don't the issues that interest me get discussed?" - Maybe they already have been--several times. Many newcomers are often chagrined to find arcane topics being discussed, with little discussion of "the basics." - This is hardly surprising....people get over the "basics" after a few months and want to move on to more exciting (to them) topics. All lists are like this. - In any case, after you've read the list for a while--maybe several weeks--go ahead and ask away. Making your topic fresher may generate more responses than, say, asking what's wrong with Clipper. (A truly overworked topic, naturally.) 2.4.9. "How did the Cypherpunks group get started?" 2.4.10. "Where did the name 'Cypherpunks' come from?" + Jude Milhon, aka St. Jude, then an editor at "Mondo 2000," was at the earliest meetings...she quipped "You guys are just a bunch of cypherpunks." The name was adopted immediately. - The 'cyberpunk' genre of science fiction often deals with issues of cyberspace and computer security ("ice"), so the link is natural. A point of confusion is that cyberpunks are popularly thought of as, well, as "punks," while many Cyberpunks are frequently libertarians and anarchists of various stripes. In my view, the two are not in conflict. - Some, however, would prefer a more staid name. The U.K. branch calls itself the "U.K. Crypto Privacy Association." <check this> However, the advantages of the name are clear. For one thing, many people are bored by staid names. For another, it gets us noticed by journalists and others. - - We are actually not very "punkish" at all. About as punkish as most of our cyberpunk cousins are, which is to say, not very. + the name - Crypto Cabal (this before the sci.crypt FAQ folks appeared, I think), Crypto Liberation Front, other names - not everybody likes the name...such is life 2.4.11. "Why doesn't the Cypherpunks group have announced goals, ideologies, and plans?" - The short answer: we're just a mailing list, a loose association of folks interested in similar things - no budget, no voting, no leadership (except the "leadership of the soapbox") - How could such a consensus emerge? The usual approach is for an elected group (or a group that seized power) to write the charter and goals, to push their agenda. Such is not the case here. - Is this FAQ a de facto statement of goals? Not if I can help it, to be honest. Several people before me planned some sort of FAQ, and had they completed them, I certainly would not have felt they were speaking for me or for the group. To be consistent, then, I cannot have others think this way about _this_ FAQ! 2.4.12. "What have the Cypherpunks actually done?" - spread of crypto: Cypherpunks have helped (PGP)...publicity, an alternative forum to sci.crypt (in many ways, better...better S/N ratio, more polite) - Wired, Whole Earth Review, NY Times, articles - remailers, encrypted remailers + The Cypherpunk- and Julf/Kleinpaste-style remailers were both written very quickly, in just days - Eric Hughes wrote the first Cypherpunks remailer in a weekend, and he spent the first day of that weekend learning enough Perl to do the job. + Karl Kleinpaste wrote the code that eventually turned into Julf's remailer (added to since, of course) in a similarly short time: - "My original anon server, for godiva.nectar.cs.cmu.edu 2 years ago, was written in a few hours one bored afternoon. It wasn't as featureful as it ended up being, but it was "complete" for its initial goals, and bug-free." [Karl_Kleinpaste@cs.cmu.edu, alt.privacy.anon-server, 1994-09-01] - That other interesting ideas, such as digital cash, have not yet really emerged and gained use even after years of active discussion, is an interesting contrast to this rapid deployment of remailers. (The text-based nature of both straight encryption/signing and of remailing is semantically simpler to understand and then use than are things like digital cash, DC-nets, and other crypto protocols.) - ideas for Perl scripts, mail handlers - general discussion, with folks of several political persuasions - concepts: pools, Information Liberation Front, BlackNet - 2.4.13. "How Can I Learn About Crypto and Cypherpunks Info?" 2.4.14. "Why is there sometimes disdain for the enthusiasm and proposals of newcomers?" - None of us is perfect, so we sometimes are impatient with newcomers. Also, the comments seen tend to be issues of disagreement--as in all lists and newsgroups (agreement is so boring). - But many newcomers also have failed to do the basic reading that many of us did literally _years_ before joining this list. Cryptology is a fairly technical subject, and one can no more jump in and expect to be taken seriously without any preparation than in any other technical field. - Finally, many of us have answered the questions of newcomers too many times to be enthusiastic about it anymore. Familiarity breeds contempt. + Newcomers should try to be patient about our impatience. Sometimes recasting the question generates interest. Freshness matters. Often, making an incisive comment, instead of just asking a basic question, can generate responses. (Just like in real life.) - "Clipper sux!" won't generate much response. 2.4.15. "Should I join the Cypherpunks mailing list?" - If you are reading this, of course, you are most likely on the Cypherpunks list already and this point is moot--you may instead be asking if you should_leave_ the List! - Only if you are prepared to handle 30-60 messages a day, with volumes fluctuating wildly 2.4.16. "Why isn't the Cypherpunks list encrypted? Don't you believe in encryption?" - what's the point, for a publically-subscribable list? - except to make people jump through hoops, to put a large burden on toad (unless everybody was given the same key, so that just one encryption could be done...which underscores the foolishness) + there have been proposals, mainly as a stick to force people to start using encryption...and to get the encrypted traffic boosted - involving delays for those who choose not or can't use crypto (students on terminals, foreigners in countries which have banned crypto, corporate subscribers....) 2.4.17. "What does "Cypherpunks write code' mean?" - a clarifying statement, not an imperative - technology and concrete solutions over bickering and chatter - if you don't write code, fine. Not everyone does (in fact, probably less than 10% of the list writes serious code, and less than 5% writes crypto or security software 2.4.18. "What does 'Big Brother Inside' Mean?" - devised by yours truly (tcmay) at Clipper meeting - Matt Thomlinson, Postscript - printed by .... 2.4.19. "I Have a New Idea for a Cipher---Should I Discuss it Here?" - Please don't. Ciphers require careful analysis, and should be in paper form (that is, presented in a detailed paper, with the necessary references to show that due diligence was done, the equations, tables, etc. The Net is a poor substitute. - Also, breaking a randomly presented cipher is by no means trivial, even if the cipher is eventually shown to be weak. Most people don't have the inclination to try to break a cipher unless there's some incentive, such as fame or money involved. - And new ciphers are notoriously hard to design. Experts are the best folks to do this. With all the stuff waiting to be done (described here), working on a new cipher is probably the least effective thing an amateur can do. (If you are not an amateur, and have broken other people's ciphers before, then you know who you are, and these comments don't apply. But I'll guess that fewer than a handful of folks on this list have the necessary background to do cipher design.) - There are a vast number of ciphers and systems, nearly all of no lasting significance. Untested, undocumented, unused- -and probably unworthy of any real attention. Don't add to the noise. 2.4.20. Are all the Cypherpunks libertarians? 2.4.21. "What can we do?" - Deploy strong crypto, to ensure the genie cannot be put in the bottle - Educate, lobby, discuss - Spread doubt, scorn..help make government programs look foolish - Sabotage, undermine, monkeywrench - Pursue other activities 2.4.22. "Why is the list unmoderated? Why is there no filtering of disrupters like Detweiler?" - technology over law - each person makes their own choice - also, no time for moderation, and moderation is usually stultifying + anyone who wishes to have some views silenced, or some posters blocked, is advised to: - contract with someone to be their Personal Censor, passing on to them only approved material - subscribe to a filtering service, such as Ray and Harry are providing 2.4.23. "What Can I Do?" - politics, spreading the word - writing code ("Cypherpunks write code") 2.4.24. "Should I publicize my new crypto program?" - "I have designed a crypting program, that I think is unbreakable. I challenge anyone who is interested to get in touch with me, and decrypt an encrypted massage." "With highest regards, Babak Sehari." [Babak Sehari, sci.crypt, 6-19-94] 2.4.25. "Ask Emily Post Crypt" + my variation on "Ask Emily Postnews" - for those that don't know, a scathing critique of clueless postings + "I just invented a new cipher. Here's a sample. Bet you can't break it!" - By all means post your encrypted junk. We who have nothing better to do with our time than respond will be more than happy to spend hours running your stuff through our codebreaking Crays! - Be sure to include a sample of encrypted text, to make yourself appear even more clueless. + "I have a cypher I just invented...where should I post it?" + "One of the very most basic errors of making ciphers is simply to add - layer upon layer of obfuscation and make a cipher which is nice and - "complex". Read Knuth on making random number generators for the - folly in this kind of approach. " <Eric Hughes, 4-17- 94, Cypherpunks> + "Ciphers carry the presumption of guilt, not innocence. Ciphers - designed by amateurs invariably fail under scrutiny by experts. This - sociological fact (well borne out) is where the presumption of - insecurity arises. This is not ignorance, to assume that this will - change. The burden of proof is on the claimer of security, not upon - the codebreaker. <Eric Hughes, 4-17-94, Cypherpunks> + "I've just gotten very upset at something--should I vent my anger on the mailing list?" - By all means! If you're fed up doing your taxes, or just read something in the newspaper that really angered you, definitely send an angry message out to the 700 or so readers and help make _them_ angry! - Find a bogus link to crypto or privacy issues to make it seem more relevant. 2.4.26. "What are some main Cypherpunks projects?" + remailers + better remailers, more advanced features - digital postage - padding, batching/latency - agent features - more of them - offshore (10 sites in 5 countries, as a minimum) - tools, services - digital cash in better forms - 2.4.27. "What about sublists, to reduce the volume on the main list." - There are already half a dozen sub-lists, devoted to planning meetings, to building hardware, and to exploring DC-Nets. There's one for remailer operators, or there used to be. There are also lists devoted to similar topics as Cypherpunks, including Robin Hanson's "AltInst" list (Alternative Institutions), Nick Szabo's "libtech-l" list, the "IMP-Interest" (Internet Mercantile Protocols) list, and so on. Most are very low volume. + That few folks have heard of any of them, and that traffic volumes are extremely low, or zero, is not all that surprising, and matches experiences elsewhere. Several reasons: - Sublists are a bother to remember; most people forget they exist, and don't think to post to them. (This "forgetting" is one of the most interesting aspects of cyberspace; successful lists seem to be Schelling points that accrete even more members, while unsuccessful lists fade away into nothingness.) - There's a natural desire to see one's words in the larger of two forums, so people tend to post to the main list. - The sublists were sometimes formed in a burst of exuberance over some topic, which then faded. - Topics often span several subinterest areas, so posting to the main list is better than copying all the relevant sublists. - In any case, the Cypherpunks main list is "it," for now, and has driven other lists effectively out of business. A kind of Gresham's Law. 2.5. Crypto 2.5.1. "Why is crypto so important?" + The three elements that are central to our modern view of liberty and privacy (a la Diffie) - protecting things against theft - proving who we say we are - expecting privacy in our conversations and writings - Although there is no explicit "right of privacy" enumerated in the U.S. Constitution, the assumption that an individual is to be secure in his papers, home, etc., absent a valid warrant, is central. (There has never been a ruling or law that persons have to speak in a language that is understandable by eavesdroppers, wiretappers, etc., nor has there ever been a rule banning private use of encrption. I mention this to remind readers of the long history of crypto freedom.) - "Information, technology and control of both _is_ power. *Anonymous* telecommunications has the potential to be the greatest equalizer in history. Bringing this power to as many as possible will forever change the discourse of power in this country (and the world)." [Matthew J Miszewski, ACT NOW!, 1993-03-06] 2.5.2. "Who uses cryptography?" - Everybody, in one form or another. We see crypto all around us...the keys in our pockets, the signatures on our driver's licenses and other cards, the photo IDs, the credit cards. Lock combinations, door keys, PIN numbers, etc. All are part of crypto (although most might call this "security" and not a very mathematical thing, as cryptography is usually thought to be). - Whitticism: "those who regularly conspire to participate in the political process are already encrypting." [Whit Diffie] 2.5.3. "Who needs crypto? What have they got to hide?" + honest people need crypto because there are dishonest people - and there may be other needs for privacy - There are many reasons why people need privacy, the ability to keep some things secret. Financial, personal, psychological, social, and many other reasons. - Privacy in their papers, in their diaries, in their pesonal lives. In their financial choices, their investments, etc. (The IRS and tax authorities in other countries claim to have a right to see private records, and so far the courts have backed them up. I disagree.) - people encrypt for the same reason they close and lock their doors - Privacy in its most basic forms 2.5.4. "I'm new to crypto--where should I start?" - books...Schneier - soda - sci.crypt - talk.politics.crypto - FAQs other than this one 2.5.5. "Do I need to study cryptography and number theory to make a contribution?" - Absolutely not! Most cryptographers and mathematicians are so busy doing their thing that they little time or interest for political and entrepreneurial activities. Specialization is for insects and researchers, as someone's .sig says. - Many areas are ripe for contribution. Modularization of functions means people can concentrate in other areas, just as writers don't have to learn how to set type, or cut quill pens, or mix inks. - Nonspecialists should treat most established ciphers as "black boxes" that work as advertised. (I'm not saying they do, just that analysis of them is best left to experts...a little skepticism may not hurt, though). 2.5.6. "How does public key cryptography work, simply put?" - Plenty of articles and textbooks describe this, in ever- increasing detail (they start out with the basics, then get to the juicy stuff). + I did find a simple explanation, with "toy numbers," from Matthew Ghio: - "You pick two prime numbers; for example 5 and 7. Multiply them together, equals 35. Now you calculate the product of one less than each number, plus one. (5-1)(7- 1)+1=21. There is a mathematical relationship that says that x = x^21 mod 35 for any x from 0 to 34. Now you factor 21, yeilds 3 and 7. "You pick one of those numbers to be your private key and the other one is your public key. So you have: Public key: 3 Private key: 7 "Someone encrypts a message for you by taking plaintext message m to make ciphertext message c: c=m^3 mod 35 "You decrypt c and find m using your private key: m=c^7 mod 35 "If the numbers are several hundred digits long (as in PGP), it is nearly impossible to guess the secret key." [Matthew Ghio, alt.anonymous, 1994-09-03] - (There's a math error here...exercise left for the student.) 2.5.7. "I'm a newcomer to this stuff...how should I get started?" - Start by reading some of the material cited. Don't worry too much about understanding it all. - Follow the list. - Find an area that interests you and concentrate on that. There is no reason why privacy advocates need to understand Diffie-Hellman key exchange in detail! + More Information + Books - Schneier - Brassard + Journals, etc - Proceedings - Journal of Cryptology - Cryptologia - Newsgroups - ftp sites 2.5.8. "Who are Alice and Bob?" 2.5.9. "What is security through obscurity"? - adding layers of confusion, indirection - rarely is strong in a an infromation-theoretic or cryptographic sense - and may have "shortcuts" (like a knot that looks complex but which falls open if approached the right way) - encryption algorithms often hidden, sites hidden - Make no mistake about it, these approaches are often used. And they can add a little to the overall security (using file encyption programs like FolderBolt on top of PGP is an example)... 2.5.10. "Has DES been broken? And what about RSA?" - DES: Brute-force search of the keyspace in chosen-plaintext attacks is feeasible in around 2^47 keys, according to Biham and Shamir. This is about 2^9 times easier than the "raw" keyspace. Michael Wiener has estimated that a macine of special chips could crack DES this way for a few thousand dollars per key. The NSA may have such machines. - In any case, DES was not expected to last this long by many (and, in fact, the NSA and NIST proposed a phaseout some years back, the "CCEP" (Commercial COMSEC Endorsement Program), but it never caught on and seems forgotten today. Clipper and EES seem to have grabbed the spotlight. - IDEA, from Europe, is supposed to be much better. - As for RSA, this is unlikely. Factoring is not yet proven to be NP-co 2.5.11. "Can the NSA Break Foo?" - DES, RSA, IDEA, etc. - Can the government break our ciphers? 2.5.12. "Can brute-force methods break crypto systems?" - depends on the system, the keyspace, the ancillary information avialable, etc. - processing power generally has been doubling every 12-18 months (Moore's Law), so.... - Skipjack is 80 bits, which is probably safe from brute force attack for 2^24 = 1.68e7 times as long as DES is. With Wiener's estimate of 3.5 hours to break DES, this implies 6700 years using today's hardware. Assuming an optimistic doubling of hardware power per year (for the same cost), it will take 24 years before the hardware costs of a brute force attack on Skipjack come down to what it now costs to attack DES. Assuming no other weaknesses in Skipjack. - And note that intelligence agencies are able to spend much more than what Wiener calculated (recall Norm Hardy's description of Harvest) 2.5.13. "Did the NSA know about public key ideas before Diffie and Hellman?" + much debate, and some sly and possibly misleading innuendo - Simmons claimed he learned of PK in Gardner's column, and he certainly should've been in a position to know (weapons, Sandia) - + Inman has claimed that NSA had a P-K concept in 1966 - fits with Dominik's point about sealed cryptosystem boxes with no way to load new keys - and consistent with NSA having essentially sole access to nation's top mathematicians (until Diffies and Hellmans foreswore government funding, as a result of the anti- Pentagon feelings of the 70s) 2.5.14. "Did the NSA know about public-key approaches before Diffie and Hellman?" - comes up a lot, with some in the NSA trying to slyly suggest that _of course_ they knew about it... - Simmons, etc. - Bellovin comments (are good) 2.5.15. "Can NSA crack RSA?" - Probably not. - Certainly not by "searching the keyspace," an idea that pops up every few months . It can't be done. 1024-bit keys implies roughly 512-bit primes, or 153-decimal digit primes. There are more than 10^150 of them! And only about 10^73 particles in the entire universe. - Has the factoring problem been solved? Probably not. And it probably won't be, in the sense that factoring is probably in NP (though this has not been proved) and P is probably not NP (also unproved, but very strongly suspected). While there will be advances in factoring, it is extremely unlikely (in the religious sense) that factoring a 300- digit number will suddenly become "easy." - Does the RSA leak information so as to make it easier to crack than it is to factor the modulus? Suspected by some, but basically unknown. I would bet against it. But more iffy than the point above. + "How strong is strong crypto?" - Basically, stronger than any of the hokey "codes" so beloved of thriller writers and movie producers. Modern ciphers are not crackable by "telling the computer to run through all the combinations" (more precisely, the number of combinations greatly exceeds the number of atoms in the universe). 2.5.16. "Won't more powerful computers make ciphers breakable?" + The effects of increasing computer power confer even *greater* advantage to the cipher user than to the cipher breaker. (Longer key lengths in RSA, for example, require polynomially more time to use, but exponentially more time to break, roughly speaking.) Stunningly, it is likely that we are close to being able to use key lengths which cannot be broken with all the computer power that will ever exist in the universe. + Analogous to impenetrable force fields protecting the data, with more energy required to "punch through" than exists in the universe - Vernor Vinge's "bobbles," in "The Peace War." - Here I am assuming that no short cuts to factoring exist...this is unproven, but suspected. (No major shortcuts, i.e., factoring is not "easy.") + A modulus of thousands of decimal digits may require more total "energy" to factor, using foreseeable approaches, than is available - reversible computation may help, but I suspect not much - Shor's quantum-mechanical approach is completely untested...and may not scale well (e.g., it may be marginally possible to get the measurement precision to use this method for, say, 100-digit numbers, but utterly impossible to get it for 120-digit numbers, let alone 1000-digit numbers) 2.5.17. "Will strong crypto help racists?" - Yes, this is a consequence of having secure virtual communities. Free speech tends to work that way! - The Aryan Nation can use crypto to collect and disseminate information, even into "controlled" nations like Germany that ban groups like Aryan Nation. - Of course, "on the Internet no one knows you're a dog," so overt racism based on superficial external characteristics is correspondingly harder to pull off. - But strong crypto will enable and empower groups who have different beliefs than the local majority, and will allow them to bypass regional laws. 2.5.18. Working on new ciphers--why it's not a Cypherpunks priority (as I see it) - It's an issue of allocation of resources. ("All crypto is economics." E. Hughes) Much work has gone into cipher design, and the world seems to have several stable, robust ciphers to choose from. Any additional work by crypto amateurs--which most of us are, relative to professional mathematicians and cipher designers--is unlikely to move things forward significantly. Yes, it could happen...but it's not likely. + Whereas there are areas where professional cryptologists have done very little: - PGP (note that PRZ did *not* take time out to try to invent his own ciphers, at least not for Version 2.0)...he concentrated on where his efforts would have the best payoff - implementation of remailers - issues involving shells and other tools for crypto use - digital cash - related issues, such as reputations, language design, game theory, etc. - These are the areas of "low-hanging fruit," the areas where the greatest bang for the buck lies, to mix some metaphors (grapeshot?). 2.5.19. "Are there any unbreakable ciphers?" - One time pads are of course information-theoretically secure, i.e., unbreakable by computer power. + For conventional ciphers, including public key ciphers, some ciphers may not be breakable in _our_ universe, in any amount of time. The logic goes as follows: - Our universe presumably has some finite number of particles (currently estimated to be 10^73 particles). This leads to the "even if every particle were a Cray Y- MP it would take..." sorts of thought experiments. But I am considering _energy_ here. Ignoring reversible computation for the moment, computations dissipate energy (some disagree with this point). There is some uppper limit on how many basic computations could ever be done with the amount of free energy in the universe. (A rough calculation could be done by calculating the energy output of stars, stuff falling into black holes, etc., and then assuming about kT per logical operation. This should be accurate to within a few orders of magnitude.) I haven't done this calculation, and won't here, but the result would likely be something along the lines of X joules of energy that could be harnessed for computation, resulting in Y basic primitive computational steps. I can then find a modulus of 3000 digits or 5000 digits, or whatever, that takes *more* than this number of steps to factor. Therefore, unbreakable in our universe. - Caveats: 1. Maybe there are really shortcuts to factoring. Certainly improvements in factoring methods will continue. (But of course these improvements are not things that convert factoring into a less than exponential-in-length problem...that is, factoring appears to remain "hard.") 2. Maybe reversible computations (a la Landauer, Bennett, et. al.) actually work. Maybe this means a "factoring machine" can be built which takes a fixed, or very slowly growing, amount of energy. In this case, "forever" means Lefty is probably right. 3. Maybe the quantum-mechanical idea of Peter Shor is possible. (I doubt it, for various reasons.) 2.5.20. "How safe is RSA?" "How safe is PGP?" "I heard that PGP has bugs?" - This cloud of questions is surely the most common sort that appears in sci.crypt. It sometimes gets no answers, sometimes gets a rude answer, and only occasionally does it lead to a fruiful discussion. - The simple anwer: These ciphers appear to be safe, to have no obvious flaws. - More details can be found in various question elsewhere in this FAQ and in the various FAQs and references others have published. 2.5.21. "How long does encryption have to be good for?" - This obviously depends on what you're encrypting. Some things need only be safe for short periods of time, e.g., a few years or even less. Other things may come back to haunt you--or get you thrown in prison--many years later. I can imagine secrets that have to be kept for many decades, even centuries (for example, one may fear one's descendents will pay the price for a secret revealed). - It is useful to think _now_ about the computer power likely to be available in the year 2050, when many of you reading this will still be around. (I'm _not_ arguing that parallelism, etc., will cause RSA to fall, only that some key lengths (e.g., 512-bit) may fall by then. Better be safe and use 1024 bits or even more. Increased computer power makes longer keys feasible, too.). 2.6. PGP 2.6.1. There's a truly vast amount of information out there on PGP, from current versions, to sites, to keyserver issues, and so on. There are also several good FAQs on PGP, on MacPGP, and probably on nearly every major version of PGP. I don't expect to compete here with these more specialized FAQs. - I'm also not a PGP expert, using it only for sending and receiving mail, and rarely doing much more with it. - The various tools, for all major platforms, are a specialty unto themselves. 2.6.2. "Where do I get PGP?" 2.6.3. "Where can I find PGP?" - Wait around for several days and a post will come by which gives some pointers. - Here are some sites current at this writing: (watch out for changes) 2.6.4. "Is PGP secure? I heard someone had...." - periodic reports, urban legend, that PGP has been compromised, that Phil Z. has been "persuaded" to.... + implausible for several reasons - Phil Z no longer controls the source code by himself - the source code is available and can be inspected...would be very difficult to slip in major back doors that would not be apparent in the source code - Phil has denied this, and the rumors appear to come from idle speculation + But can PGP be broken? - has not been tested independently in a thorough, cryptanalytic way, yet (opinion of tcmay) - NSA isn't saying + Areas for attack + IDEA - some are saying doubling of the number of rounds should be donee - the random number generators...Colin Plumb's admission 2.6.5. "Should I use PGP and other crypto on my company's workstations?" - machines owned by corporations and universities, usually on networks, are generally not secure (that is, they may be compromised in various ways) - ironically, most of the folks who sign all their messages, who use a lot of encryption, are on just such machines - PCs and Macs and other nonnetworked machines are more secure, but are harder to use PGP on (as of 1994) - these are generalizations--there are insecure PCs and secure workstations 2.6.6. "I just got PGP--should I use it for all my mail?" - No! Many people cannot easily use PGP, so if you wish to communicate with them, don't encrypt everything. Use encryption where it matters. - If you just want more people to use encryption, help with the projects to better integrate crypto into existing mailers. 2.6.7. NSA is apparently worried about PGP, worried about the spread of PGP to other countries, and worried about the growth of "internal communities" that communicate via "black pipes" or "encrypted tunnels" that are impenetrable to them. 2.7. Clipper 2.7.1. "How can the government do this?" - incredulity that bans, censorship, etc. are legal + several ways these things happen - not tested in the courts - wartime regulations + conflicting interpretations - e.g., "general welfare" clause used to justify restrictions on speech, freedom of association, etc. + whenever public money or facilities used (as with churches forced to hire Satanists) - and in this increasingly interconnnected world, it is sometimes very hard to avoid overlap with public funding, facilities, etc. 2.7.2. "Why don't Cypherpunks develop their won competing encryption chip?" + Many reasons not to: - cost - focus - expertise - hard to sell such a competing standard - better to let market as a whole make these choices 2.7.3. "Why is crypto so frightening to governments?" + It takes away the state's power to snoop, to wiretap, to eavesdrop, to control - Priestly confessionals were a major way the Church kept tabs on the locals...a worldwide, grassroots system of ecclesiastical narcs + Crypto has high leverage + Unlike direct assaults with bombs, HERF and EMP attacks, sabotage, etc, crypto is self-spreading...a bootstrap technology - people use it, give it to others, put it on networks - others use it for their own purposes - a cascade effect, growing geometrically - and undermining confidence in governments, allowing the spread of multiple points of view (especially unapproved views) 2.7.4. "I've just joined the list and am wondering why I don't see more debate about Clipper?" - Understand that people rarely write essays in response to questions like "Why is Clipper bad?" For most of us, mandatory key escrow is axiomatically bad; no debate is needed. - Clipper was thoroughly trashed by nearly everyone within hours and days of its announcement, April 16, 1993. Hundreds of articles and editorials have condemned it. Cyperpunks currently has no active supporters of mandatory key escrow, from all indications, so there is nothing to debate. 2.8. Other Ciphers and Crypto Products 2.9. Remailers and Anonymity 2.9.1. "What are remailers?" 2.9.2. "How do remailers work?" (a vast number of postings have dealt with this) - The best way to understand them is to "just do it," that is, send a few remailed message to yourself, to see how the syntax works. Instructions are widely available--some are cited here, and up to date instructions will appear in the usual Usenet groups. - The simple view: Text messages are placed in envelopes and sent to a site that has agreed to remail them based on the instructions it finds. Encryption is not necessary--though it is of course recommended. These "messages in bottles" are passed from site to site and ultimately to the intended final recipient. - The message is pure text, with instructions contained _in the text_ itself (this was a fortuitous choice of standard by Eric Hughes, in 1992, as it allowed chaining, independence from particular mail systems, etc.). - A message will be something like this: :: Request-Remailing-To: remailer@bar.baz Body of text, etc., etc. (Which could be more remailing instructions, digital postage, etc.) - These nested messages make no assumptions about the type of mailer being used, so long as it can handle straight ASCII text, which all mailers can of course. Each mail message then acts as a kind of "agent," carrying instructions on where it should be mailed next, and perhaps other things (like delays, padding, postage, etc.) - It's very important to note that any given remailer cannot see the contents of the envelopes he is remailing, provided encryption is used. (The orginal sender picks a desired trajectory through the labyrinth of remailers, encrypts in the appropriate sequence (last is innermost, then next to last, etc.), and then the remailers sequentially decrypt the outer envelopes as they get them. Envelopes within envelopes.) 2.9.3. "Can't remailers be used to harass people?" - Sure, so can free speech, anonymous physical mail ("poison pen letters"), etc. - With e-mail, people can screen their mail, use filters, ignore words they don't like, etc. Lots of options. "Sticks and stones" and all that stuff we learned in Kindergarten (well, I'm never sure what the the Gen Xers learned....). - Extortion is made somewhat easier by anonymous mailers, but extortion threats can be made in other ways, such as via physical mail, or from payphones, etc. - Physical actions, threats, etc. are another matter. Not the domain of crypto, per se. 2.10. Surveillance and Privacy 2.10.1. "Does the NSA monitor this list?" - Probably. We've been visible enough, and there are many avenues for monitoring or even subscribing to the List. Many aliases, many points of presence. - some concerns that Cypherpunks list has been infiltrated and is a "round up list" - There have even been anonymous messages purporting to name likely CIA, DIA, and NSA spooks. ("Be aware.") - Remember, the list of subscribers is _not_ a secret--it can be gotten by sending a "who cypherpunks" message to majordomo@toad.com. Anyone in the world can do this. 2.10.2. "Is this list illegal?" - Depends on the country. In the U.S., there are very strong protections against "prior restraint" for published material, so the list is fairly well -protected....shutting it down would create a First Amendment case of major importance. Which is unlikely. Conspiracy and sedition laws are more complex to analyze; there are no indications that material here or on the list is illegal. - Advocacy of illegal acts (subversion of export laws, espionage, etc.) is generally legal. Even advocating the overthrow of the government. - The situation in other countries is different. Some countries ban unapproved encryption, so this list is suspect. - Practically speaking, anyone reading this list is probably in a place which either makes no attempt to control encryption or is unable to monitor what crosses its borders. 2.10.3. "Can keystrokes really be monitored remotely? How likely is this?" - Yes. Van Eck, RF, monitors, easy (it is claimed) to build this - How likely? Depends on who you are. Ames, the KGB spy, was probably monitored near the end, but I doubt many of us are. The costs are simply too high...the vans outside, the personnel needed, etc. - the real hazards involve making it "easy" and "almost automatic" for such monitoring, such as with Clipper and EES. Then they essentially just flip a switch and the monitoring happens...no muss, no fuss. 2.10.4. "Wouldn't some crimes be stopped if the government could monitor what it wanted to?" - Sure. This is an old story. Some criminals would be caught if their diaries could be examined. Television cameras in all homes would reduce crimes of .... (Are you listening, Winston?). - Orwell, fascism, surveillance states, what have you got to hide, etc. 2.11. Legal 2.11.1. "Can encryption be banned?" - ham operators, shortwave - il gelepal, looi to waptime aolditolq + how is this any different from requiring speech in some language? - Navaho code talkers of WW2,,,,modern parallel 2.11.2. "Will the government try to ban encryption?" - This is of course the major concern most of us have about Clipper and the Escrowed Encryption Standard in general. Even if we think the banning of crypto will ultimately be a failure ("worse than Prohibition," someone has said), such a ban could make things very uncomfortable for many and would be a serious abridgement of basic liberties. - We don't know, but we fear something along these lines. It will be difficult to enforce such a ban, as so many avenues for communication exist, and encrypted messages may be hard to detect. - Their goal, however, may be _control_ and the chilling effect that using "civil forfeiture" may have on potential crypto users. Like the drug laws. (Whit Diffie was the first to emphasize this motivation.) 2.11.3. "How could encryption be banned?" - most likely way: restrictions on networks, a la airwaves or postal service - could cite various needs, but absent a mechanism as above, hard to do - an outright ban, enforced with civil forfeiture penalties - wartime sorts of policies (crypto treated as sedition, treason...some high-profile prison sentences) - scenario posted by Sandfort? 2.11.4. "What's the situation about export of crypto?" + There's been much debate about this, with the case of Phil Zimmermann possibly being an important test case, should charges be filed. - as of 1994-09, the Grand Jury in San Jose has not said anything (it's been about 7-9 months since they started on this issue) - Dan Bernstein has argued that ITAR covers nearly all aspects of exporting crypto material, including codes, documentation, and even "knowledge." (Controversially, it may be in violation of ITAR for knowledgeable crypto people to even leave the country with the intention of developing crypto tools overseas.) - The various distributions of PGP that have occurred via anonymous ftp sources don't imply that ITAR is not being enforced, or won't be in the future. 2.11.5. "What's the legal status of digital signatures?" - Not yet tested in court. Ditto for most crypto protocols, including digital timestamping, electronic contracts, issues of lost keys, etc. 2.11.6. "Can't I just claim I forgot my password?" 2.11.7. "Is it dangerous to talk openly about these ideas?" - Depends on your country. In some countries, perhaps no. In the U.S., there's not much they can do (though folks should be aware that the Cypherpunks have received a lot of attention by the media and by policy makers, and so a vocal presence on this list very likely puts one on a list of crypto trouble makers). - Some companies may also feel views expressed here are not consistent with their corporate policies. Your mileage may vary. - Sedition and treason laws are not likely to be applicable. - some Cypherpunks think so - Others of us take the First Amendment pretty seriously: that _all_ talk is permissable - NSA agents threatened to have Jim Bidzos killed 2.11.8. "Does possession of a key mean possession of *identity*?" - If I get your key, am I you? - Certainly not outside the context of the cryptographic transaction. But within the context of a transaction, yes. Additional safeguards/speedbumps can be inserted (such as biometric credentials, additional passphrases, etc.), but these are essentially part of the "key," so the basic answer remains "yes." (There are periodically concerns raised about this, citing the dangers of having all identity tied to a single credential, or number, or key. Well, there are ways to handle this, such as by adopting protocols that limit one's exposure, that limits the amount of money that can be withdrawn, etc. Or people can adopt protocols that require additional security, time delays, countersigning, etc.) + This may be tested in court soon enough, but the answer for many contracts and crypto transactions will be that possession of key = possession of identity. Even a court test may mean little, for the types of transactions I expect to see. - That is, in anonymous systems, "who ya gonna sue?" - So, guard your key. 2.12. Digital Cash 2.12.1. "What is digital money?" 2.12.2. "What are the main uses of strong crypto for business and economic transactions?" - Secure communications. Ensuring privacy of transaction records (avoiding eavesdroppes, competitors) - Digital signatures on contracts (will someday be standard) - Digital cash. - Reputations. - Data Havens. That bypass local laws about what can be stored and what can't (e.g., silly rules on how far back credit records can go). 2.12.3. "What are smart cards and how are they used?" + Most smart cards as they now exist are very far from being the anonymous digital cash of primary interest to us. In fact, most of them are just glorified credit cards. - with no gain to consumers, since consumes typically don't pay for losses by fraud - (so to entice consumes, will they offer inducements?) - Can be either small computers, typically credit-card-sized, or just cards that control access via local computers. + Tamper-resistant modules, e.g., if tampered with, they destroy the important data or at the least give evidence of having been tampered with. + Security of manufacturing - some variant of "cut-and-choose" inspection of premises + Uses of smart cards - conventional credit card uses - bill payment - postage - bridge and road tolls - payments for items received electronically (not necessarily anonymously) 2.13. Crypto Anarchy 2.13.1. "What is Crypto Anarchy?" - Some of us believe various forms of strong cryptography will cause the power of the state to decline, perhaps even collapse fairly abruptly. We believe the expansion into cyberspace, with secure communications, digital money, anonymity and pseudonymity, and other crypto-mediated interactions, will profoundly change the nature of economies and social interactions. Governments will have a hard time collecting taxes, regulating the behavior of individuals and corporations (small ones at least), and generally coercing folks when it can't even tell what _continent_ folks are on! Read Vinge's "True Names" and Card's "Ender's Game" for some fictional inspirations. "Galt's Gulch" in cyberspace, what the Net is rapidly becoming already. I call this set of ideas "crypto anarchy" (or "crypto- anarchy," as you wish) and have written about this extensively. The magazines "Wired" (issue 1.2), "Whole Earth Review" (Summer, 1993), and "The Village Voice" (Aug. 6th, 1993) have all carried good articles on this. 2.13.2. The Crypto Anarchist Manifesto - a complete copy of my 1988 pastiche of the Communisto Manifesto is included in the chapter on Crypto Anarchy. - it needs rewriting, but for historical sake I've left it unchanged. - I'm proud that so much of it remains accurate. 2.13.3. "What is BlackNet?" - BlackNet -- an experiment in information markets, using anonymous message pools for exchange of instructions and items. Tim May's experiment in guerilla ontology. - BlackNet -- an experimental scheme devised by T. May to underscore the nature of anonymous information markets. "Any and all" secrets can be offered for sale via anonymous mailers and message pools. The experiment was leaked via remailer to the Cypherpunks list (not by May) and thence to several dozen Usenet groups by Detweiler. The authorities are said to be investigating it. 2.13.4. "What effect will crypto have on governments?" - A huge topic, one I've been thinking about since late 1987 when it dawned on me that public key crypto and anonymous digital cash systems, information markets, etc. meant the end of governments as we know them. (I called this development "crypto anarchy." Not everyone is a fan of it. But it's coming, and fast.) - "Putting the NSA out of business," as the NYT article put it - Espionage is changing. To pick one example, "digital dead drops." Any message can be sent through an untraceable path with remailers....and then posted in encrypted form in a newsgroup readable in most countries, including the Former Soviet Union. This means the old stand by of the microfilm in a Coke can left by a certain tree on a rural road--a method fraught with delays, dangers, and hassles--is now passe. The same message can be send from the comfort of one's home securely and untraceably. Even with a a digital signature to prevent spoofing and disinformation. This spy can be a Lockheed worker on the Aurora program, a SIGINT officer at Woomera, or a disgruntled chip designer at Motorola. (Yes, a countermeasure is to limit access to personal computers, to run only standard software that has no such crypto capability. Such embargoes may already apply to some in sensitive positions, and may someday be a condition of employment.) - Money-laundering - Tax collection. International consultants. Perpetual tourists. Virtual corporations. - Terrorism, assassination, crime, Triads, Yakuza, Jamaicans, Russian Mafia...virtual networks... Aryan Nation gone digital 2.13.5. "How quickly could something like crypto anarchy come?" - Parts of it are happening already, though the changes in the world are not something I take any credit for. Rather, there are ongoing changes in the role of nations, of power, and of the ability to coerce behaviors. When people can drop out of systems they don't like, can move to different legal or tax jurisdictions, then things change. + But a phase change could occur quickly, just as the Berlin Wall was impregnable one day, and down the next. - "Public anger grows quietly and explodes suddenly. T.C. May's "phase change" may be closer than we think. Nobody in Russia in 1985 really thought the country would fall apart in 6 years." [Mike Ingle, 1994-01-01] 2.13.6. "Could strong crypto be used for sick and disgusting and dangerous purposes?" - Of course. So can locked doors, but we don't insist on an "open door policy" (outside of certain quaint sorority and rooming houses!) So do many forms of privacy allow plotters, molestors, racists, etc. to meet and plot. - Crypto is in use by the Aryan Nation, by both pro- and anti- abortion groups, and probably by other kinds of terrorists. Expect more uses in the future, as things like PGP continue to spread. - Many of us are explicity anti-democratic, and hope to use encryption to undermine the so-called democratic governments of the world 2.13.7. "What is the Dining Cryptographers Problem, and why is it so important?" + This is dealt with in the main section, but here's David Chaum's Abstract, from his 1988 paper" - Abstract: "Keeping confidential who sends which messages, in a world where any physical transmission can be traced to its origin, seems impossible. The solution presented here is unconditionally or cryptographically secure, depending on whether it is based on one-time-use keys or on public keys. respectively. It can be adapted to address efficiently a wide variety of practical considerations." ["The Dining Cryptographers Problem: Unconditional Sender and Recipient Untraceability," David Chaum, Journal of Cryptology, I, 1, 1988.] - - DC-nets have yet to be implemented, so far as I know, but they represent a "purer" version of the physical remailers we are all so familiar with now. Someday they'll have have a major impact. (I'm a bigger fan of this work than many seem to be, as there is little discussion in sci.crypt and the like.) 2.13.8. "Why won't government simply ban such encryption methods?" + This has always been the Number One Issue! - raised by Stiegler, Drexler, Salin, and several others (and in fact raised by some as an objection to my even discussing these issues, namely, that action may then be taken to head off the world I describe) + Types of Bans on Encryption and Secrecy - Ban on Private Use of Encryption - Ban on Store-and-Forward Nodes - Ban on Tokens and ZKIPS Authentication - Requirement for public disclosure of all transactions + Recent news (3-6-92, same day as Michaelangelo and Lawnmower Man) that government is proposing a surcharge on telcos and long distance services to pay for new equipment needed to tap phones! - S.266 and related bills - this was argued in terms of stopping drug dealers and other criminals - but how does the government intend to deal with the various forms fo end-user encryption or "confusion" (the confusion that will come from compression, packetizing, simple file encryption, etc.) + Types of Arguments Against Such Bans - The "Constitutional Rights" Arguments + The "It's Too Late" Arguments - PCs are already widely scattered, running dozens of compression and encryption programs...it is far too late to insist on "in the clear" broadcasts, whatever those may be (is program code distinguishable from encrypted messages? No.) - encrypted faxes, modem scramblers (albeit with some restrictions) - wireless LANs, packets, radio, IR, compressed text and images, etc....all will defeat any efforts short of police state intervention (which may still happen) + The "Feud Within the NSA" Arguments - COMSEC vs. PROD + Will affect the privacy rights of corporations - and there is much evidence that corporations are in fact being spied upon, by foreign governments, by the NSA, etc. + They Will Try to Ban Such Encryption Techniques + Stings (perhaps using viruses and logic bombs) - or "barium," to trace the code + Legal liability for companies that allow employees to use such methods - perhaps even in their own time, via the assumption that employees who use illegal software methods in their own time are perhaps couriers or agents for their corporations (a tenuous point) 2.13.9. "Could anonymous markets facilitate repugnant services, such as killings for hire?" - Yes, though there are some things which will help lessen the full impact. - To make this brutally concrete, here's how escrow makes murder contracts much safer than they are today to negotiate. Instead of one party being caught in an FBI sting, as is so often the case when amateurs try to arrange hits, they can use an escrow service to insulate themselves from: 1. From being traced, because the exchanges are handled via pseudonyms 2. From the killer taking the money and then not performing the hit, because the escrow agent holds the money until the murder is verified (according to some prototocol, such a newspaper report...again, an area for more work, thankfully). 3. From being arrested when the money is picked up, as this is all done via digital cash. There are some ways to reduce the popularity of this Murder, Incorporated system. (Things I've been thinking about for about 6 years, and which we discussed on the Cypherpunks list and on the Extropians list.) 2.14. Miscellaneous 2.14.1. "Why can't people just agree on an approach?" - "Why can't everyone just support my proposal?" - "I've proposed a new cipher, but nobody's interested...you Cypherpunks just never _do_ anything!" - This is one of the most consistently divisive issues on the list. Often a person will become enamored of some approach, will write posts exhorting others to become similarly enamored, urging others to "do something!," and will then, when no interest is evidenced, become irate. To be more concrete, this happens most often with various and sundry proposals for "digital money." A close second is for various types of "Cypherpunks activism," with proposals that we get together and collect a few million dollars to run Ross Perot-type advertisements urging people to use PGP, with calls for a "Cypherpunks radio show," and so on. (Nothing wrong with people doing these things, I suppose. The problem lies in the exhortation of _others_ to do these things.) - This collective action is always hard to achieve, and rightly so, in my opinion. Emergent behavior is more natural, and more efficient. And hence better. + the nature of markets, agents, different agendas and goals - real standards and markets evolve - sometimes because of a compelling exemplar (the Walkman, PGP), sometimes because of hard work by standards committees (NTSC, electric sockets, etc.) - but almost never by simple appeals to correctness or ideological rightness 2.14.2. "What are some of the practical limits on the deployment of crypto, especially things like digital cash and remailers?" + Lack of reliable services - Nodes go down, students go home for the summer, downtime for various reasons - Lack of robustness 2.14.3. "Is crypto dominated by mistrust? I get the impression that everything is predicated on mutual mistrust." - We lock our doors...does this mean we are lacking in trust? No, it means we understand there are _some_ out there who will exploit unlocked doors. Ditto for the crypto world. - "Trust, but verify," as Ronald Reagan used to say. Mutual mistrust can actually make for a more trustworthy environment, paradoxical as that may sound. "Even paranoids have enemies." - The danger in a trusting environment that lacks other mechanisms is that "predators" or "defectors" (in game- theoretic terms) can exploit this trusting environment. Confidence games, scams, renegging on deals, and even outright theft. - Crypto offers the opportunity for "mutually suspicious agents" to interact without explicit "trust." 2.14.4. "Who is Detweiler?" + S. Boxx, an12070, ldxxyyy, Pablo Escobar, Hitler, Linda Lollipop, Clew Lance Simpleton, tmp@netcom.com, Jim Riverman - often with my sig block, or variants of it, attached - even my phone number - he lost his ColoState account for such tactics... - electrocrisy - cypherwonks 2.14.5. "Who is Sternlight?" - A retired policy analyst who is often contentious in Usenet groups and supportive of government policies on crypto policy. Not nearly as bad as Detweiler. 2.15. More Information and References 2.15.1. "Where can I find more information?" - Well, this is a start. Also, lots of other FAQs and Mosaic home pages (URLs) exist, encompassing a vast amount of knowledge. - As long as this FAQ is, it can only scratch the surface on many topics. (I'm especially amused when someone says they've looked for a FAQ on some obscure topic. No FAQ is likely to answer all questions, especially obcure ones.) - Many articles and papers are available at the ftp.csua.berkeley.edu site, in pub/cypherpunks. Look around there. The 1981 Chaum paper on untraceabel e-mail is not (too many equations for easy scanning), but the 1988 paper on Dining Cryptographers Nets is. (I laboriously scanned it and OCRed it, back when I used to have the energy to do such thankless tasks.) + Some basic sources: + Sci.crypt FAQ, published regularly, Also available by anonymous ftp at rtfm.mit.edu. And in various URLs, including: - URLs for sci.crypt FAQ: xxxxxx - RSA Data Security Inc. FAQ - Bruce Schneier's "Applied Cryptography" book, 1993. Every reader of this list should get this book! - The "online generation" tends to want all material online, I know, but most of the good stuff is to be found in paper form, in journals and books. This is likely to be the case for many years to come, given the limitation of ASCII, the lack of widespread standards (yes, I know about LaTex, etc.), and the academic prestige associated with bound journals and books. Fortunately, you can _all_ find universit libraries within driving range. Take my advice: if you do not spend at least an entire Saturday immersing yourself in the crypto literature in the math section of a large library, perusing the "Proceeedings of the Crypto Conference" volumes, scanning the textbooks, then you have a poor foundation for doing any crypto work. 2.15.2. "Things are changing quickly. Not all of the addresses and URLs given here are valid. And the software versions... How do I get the latest information?" - Yes, things are changing quickly. This document can't possibly keep up with the rapid changes (nor can its author!). - Reading the various newsgroups is, as always, the best way to hear what's happening on a day to day basis. Web pages, gopher, archie, veronica, etc. should show the latest versions of popular software packages. 2.15.3. "FUQs: "Frequently Unanswered Questions"?" - (more to be added) - With 700 or more people on the Cypherpunks list (as of 94- 09), it is inevitable that some FAQs will go unanswered when newbies (or others) ask them. Sometimes the FUQs are ignored because they're so stale, other times because to answer them is to continue and unfruitful thread. + "P = NP?" - Steve Smale has called this the most important new unsolved problem of the past half-century. - If P were (unexpectedly) proved to be NP + Is RSA and factoring in NP? - not yet proved - factoring might be easier - and RSA might be easier than factoring in general (e.g., chosen- and known-plaintext may provide clues) - "Will encryption be outlawed? What will happen?" + "Is David Sternlight an NSA agent?" - Seriously, David S. is probably what he claims: a retired economist who was once very senior in government and corporate policy circles. I have no reason to doubt him. - He has views at odds with most of us, and a baiting style of expressing his views, but this does not mean he is a government agent as so many people claim. - Not in the same class as Detweiler. 3. Cypherpunks -- History, Organization, Agenda 3.1. copyright THE CYPHERNOMICON: Cypherpunks FAQ and More, Version 0.666, 1994-09-10, Copyright Timothy C. May. All rights reserved. See the detailed disclaimer. Use short sections under "fair use" provisions, with appropriate credit, but don't put your name on my words. 3.2. SUMMARY: Cypherpunks -- History, Organization, Agenda 3.2.1. Main Points - Cypherpunks formed in September, 1992 - formed at an opportune time, with PGP 2.0, Clipper, etc. hitting - early successes: Cypherpunks remailers, publicity 3.2.2. Connections to Other Sections 3.2.3. Where to Find Additional Information - "Wired," issue 1.2, had a cover story on Cypherpunks. - "Whole Earth Review," Summer 1993, had a long article on crypto and Cypherpunks (included in the book "Out of Control," by Kevin Kelly. - "Village Voice," August 6th (?). 1993, had cover story on "Crypto Rebels" (also reprinted in local weeklies) - and numerous articles in various magazines 3.2.4. Miscellaneous Comments - the best way to get a feel for the List is to simply read it for a while; a few months should do. 3.3. The Cypherpunks Group and List 3.3.1. What is it? + Formal Rules, Charter, etc.? - no formal rules or charter - no agreed-upon mission 3.3.2. "Who are the Cypherpunks?" - A mix of about 500-700 + Can find out who by sending message to majordomo@toad.com with the message body text "who cypherpunks" (no quotes, of course). - Is this a privacy flaw? Maybe. - Lots of students (they have the time, the Internet accounts). Lots of computer science/programming folks. Lots of libertarians. - quote from Wired article, and from "Whole Earth Review" 3.3.3. "How did the Cypherpunks group get started?" + History? - Discussions between Eric Hughes and me, led to Eric's decision to host a gathering + First meeting was, by coincidence, the same week that PGP 2.0 was released...we all got copies that day - morning session on basics - sitting on the floor + afternoon we played the "Crypto Game" - remailers, digital money, information for sale, etc. - John Gilmore offered his site to host a mailing list, and his company's offices to hold monthly meetings - The mailing list began almost immediately - The Name "Cypherpunks"? 3.3.4. "Should I join the Cypherpunks mailing list?" - If you are reading this, of course, you are most likely on the Cypherpunks list already and this point is moot--you may instead be asking if you should_leave_ the List! - Only if you are prepared to handle 30-60 messages a day, with volumes fluctuating wildly 3.3.5. "How can I join the Cypherpunk mailing list?" - send message to "majordomo@toad.com" with a _body_ text of "subscribe cypherpunks" (no quote marks in either, of course). 3.3.6. "Membership?" - about 500-700 at any given time - many folks join, are overwhelmed, and quit - other groups: Austin, Colorado, Boston, U.K. 3.3.7. "Why are there so many libertarians on the Cypherpunks list?" + The same question is often asked about the Net in general. Lots of suggested reasons: - A list like Cypherpunks is going to have privacy and freedom advocates. Not all privacy advocates are libertarians (e.g., they may want laws restricting data collection), but many are. And libertarians naturally gravitate to causes like ours. - Net grew anarchically, with little control. This appeals to free-wheeling types, used to making their own choices and building their own worlds. - Libertarians are skeptical of central control structures, as are most computer programming types. They are skeptical that a centrally-run control system can coordinate the needs and desires of people. (They are of course more than just "skeptical" about this.) - In any case, there's not much of a coherent "opposition camp" to the anarcho-capitalist, libertarian ideology. Forgive me for saying this, my non-libertarian friends on the list, but most non-libertarian ideologies I've seen expressed on the list have been fragmentary, isolated, and not coherent...comments about "how do we take care of the poor?" and Christian fundamentalism, for example. If there is a coherent alternative to a basically libertarian viewpoint, we haven't seen it on the list. - (Of course, some might say that the libertarians outshout the alternatives...I don't think this is really so.) 3.3.8. "How did the mailing list get started?" - Hugh Daniel, Eric Hughes, and I discussed this the day after the first meeting - mailing list brought together diverse interests - How to hoin? 3.3.9. "How did Cypherpunks get so much early publicity?" - started at the right time, just as PGP was gaining popularity, as plans for key escrow were being laid (I sounded an alarm in October, 1992, six months before the Clipper announcement), and just as "Wired" was preparing its first issue - Kevin Kelly and Steven Levy attended some of our early meetings, setting the stage for very favorable major stories in "Wired" (issue 1.2, the cover story), and "Whole Earth Review" (Summer, 1993) - a niche for a "renegade" and "monkey-wrenching" group, with less of a Washington focus - publicity in "Wired," "The Whole Earth Review," "The Village Voice" + Clipper bombshell occupied much of our time, with some effect on policy - climate of repudiation - links to EFF, CPSR, etc. 3.3.10. "Why the name?" - Jude Milhon nicknames us - cypherpunkts? (by analogy with Mikropunkts, microdots) 3.3.11. "What were the early meetings like?" - cypherspiel, Crypto Anarchy Game 3.3.12. "Where are places that I can meet other Cypherpunks?" - physical meetings - start your own...pizza place, classroom + other organizations - + "These kind of meetings (DC 2600 meeting at Pentagon City Mall, 1st Fri. of - every month in the food court, about 5-7pm or so) might be good places for - local cypherpunks gatherings as well. I'm sure there are a lot of other - such meetings, but the DC and Baltimore ones are the ones I know of. <Stanton McCandlish, 7 April 1994> - (note that the DC area already meets...) - Hackers, raves - regional meetings 3.3.13. "Is the Cypherpunks list monitored? Has it been infiltrated?" - Unknown. It wouldn't be hard for anyone to be monitoring the list. - As to infiltration, no evidence for this. No suspicious folks showing up at the physical meetings, at least so far as I can see. (Not a very reliable indication.) 3.3.14. "Why isn't there a recruiting program to increase the number of Cypherpunks?" - Good question. The mailing list reached about 500 subscribers a year or so ago and has remained relatively constant since then; many subscribers learned of the list and its address in the various articles that appeared. - Informal organizations often level out in membership because no staff exists to publicize, recruit, etc. And size is limited because a larger group loses focus. So, some stasis is achieved. For us, it may be at the 400-700 level. It seems unlikely that list membership would ever get into the tens of thousands. 3.3.15. "Why have there been few real achievements in crypto recently?" + Despite the crush of crypto releases--the WinPGPs, SecureDrives, and dozen other such programs--the fact is that most of these are straightforward variants on what I think have been the two major product classes to be introduced in the last several years" - PGP, and variants. - Remailers, and variants. - These two main classes account for about 98% of all product- or version-oriented debate on the Net, epitomized by the zillions of "Where can I find PGP2.6ui for the Amiga?" sorts of posts. + Why is this so? Why have these dominated? What else is needed? + First, PGP gave an incredible impetus to the whole issue of public use of crypto. It brought crypto to the masses, or at least to the Net-aware masses. Second, the nearly simultaneous appearance of remailers (the Kleinpaste/Julf- style and the Cypherpunks "mix"-style) fit in well with the sudden awareness about PGP and crypto issues. And other simultaneous factors appeared: - the appearance of "Wired" and its spectacular success, in early 1993 - the Clipper chip firestorm, beginning in April 1993 - the Cypherpunks group got rolling in late 1992, reaching public visibility in several articles in 1993. (By the end of '93, we seemed to be a noun, as Bucky might've said.) + But why so little progress in other important areas? - digital money, despite at least a dozen reported projects, programs (only a few of which are really anything like Chaum's "digital cash") - data havens, information markets, etc. - money-laundering schemes, etc. + What could change this? - Mosaic, WWW, Web - A successful digital cash effort 3.4. Beliefs, Goals, Agenda 3.4.1. "Is there a set of beliefs that most Cypherpunks support?" + There is nothing official (not much is), but there is an emergent, coherent set of beliefs which most list members seem to hold: * that the government should not be able to snoop into our affairs * that protection of conversations and exchanges is a basic right * that these rights may need to be secured through _technology_ rather than through law * that the power of technology often creates new political realities (hence the list mantra: "Cypherpunks write code") + Range of Beliefs - Many are libertarian, most support rights of privacy, some are more radical in apppoach 3.4.2. "What are Cypherpunks interested in?" - privacy - technology - encryition - politics - crypto anarchy - digital money - protocols 3.4.3. Personal Privacy and Collapse of Governments - There seem to be two main reasons people are drawn to Cypherpunks, besides the general attractiveness of a "cool" group such as ours. The first reason is _personal privacy_. That is, tools for ensuring privacy, protection from a surveillance society, and individual choice. This reason is widely popular, but is not always compelling (after all, why worry about personal privacy and then join a list that has been identified as a "subversive" group by the Feds? Something to think about.) - The second major is personal liberty through reducing the power of governments to coerce and tax. Sort of a digital Galt's Gulch, as it were. Libertarians and anarchocapitalists are especially drawn to this vision, a vision which may bother conventional liberals (when they realize strong crypto means things counter to welfare, AFDC, antidiscrimination laws....). - This second view is more controversial, but is, in my opinion, what really powers the list. While others may phrase it differently, most of us realize we are on to something that will change--and already is changing--the nature of the balance of power between individuals and larger entities. 3.4.4. Why is Cypherpunks called an "anarchy"? - Anarchy means "without a leader" (head). Much more common than people may think. - The association with bomb-throwing "anarchists" is misleading. 3.4.5. Why is there no formal agenda, organization, etc.? - no voting, no organization to administer such things - "if it ain't broke, don't fix it" - and it's how it all got started and evolved - also, nobody to arrest and hassle, no nonsense about filling out forms and getting tax exemptions, no laws about campaign law violations (if we were a formal group and lobbied against Senator Foo, could be hit with the law limiting "special interests," conceivably) 3.4.6. How are projects proposed and completed? - If an anarchy, how do things get done? - The way most things get done: individual actions and market decisions. 3.4.7. Future Needs for Cyberspace + Mark Pesci's ideas for VR and simulations - distributed, high bandwidth - a billion users - spatial ideas....coordinates...servers...holographic models - WWW plus rendering engine = spatial VR (Library of Congress) - "The Labyrinth" + says to avoid head-mounted displays and gloves (bad for you) + instead, "perceptual cybernetics". - phi--fecks--psi (phi is external world,Fx = fects are effectuators and sensors, psi is your internal state) 3.4.8. Privacy, Credentials without identity 3.4.9. "Cypherpunks write code" - "Cypherpunks break the laws they don't like" - "Don't get mad, get even. Write code." 3.4.10. Digital Free Markets + strong crypto changes the nature and visibility of many economic transactionst, making it very difficult for governments to interfere or even to enforce laws, contracts, etc. - thus, changes in the nature of contract enforcement + (Evidence that this is not hopeless can be found in several places: - criminal markets, where governments obviously cannot be used - international markets, a la "Law Merchant" - "uttering a check" - shopping malls in cyberspace...no identifiable national or regional jurisdiction...overlapping many borders... + caveat emptor (though rating agencies, and other filter agents, may be used by wary customers....ironically, reputation will matter even more than it now does) - no ability to repudiate a sale, to be an Indian giver - in all kinds of information.... 3.4.11. The Role of Money - in monetarizing transactions, access, remailers---digital postage 3.4.12. Reductions on taxation - offshore entities already exempt - tax havens - cyberspace localization is problematic 3.4.13. Transnationalism - rules of nations are ignored 3.4.14. Data Havens - credit, medical, legal, renter, etc. 3.4.15. MOOs, MUDs, SVRs, Habitat cyberspaces - "True Names" and "Snow Crash" - What are + Habitat....Chip and Randy - Lucasfilm, Fujitsu - started as game environment... - many-user environments - communications bandwidth is a scarce resource - object-oriented data representation + implementation platform unimportant...range of capabilities - pure text to Real ity Engines - never got as far as fully populating the reality - "detailed central planning is impossible; don't even try" - 2-D grammar for layouts + "can't trust anyone" - someone disassembled the code and found a way to make themselves invisible - ways to break the system (extra money) + future improvements - multimedia objects, customizable objects, local turfs, mulitple interfaces - "Global Cyberspace Infrastructure" (Fujitsu, FINE) + more bandwidth means more things can be done - B-ISDN will allow video on demand, VR, etc. - protocol specs, Joule (secure concurrent operating system) - intereaction spaces, topological (not spatial) + Xerox, Pavel Curtis + LambdaMOO - 1200 different users per day, 200 at a time, 5000 total users - "social virtual realities"--virtual communities - how emergent properties emerge - pseudo-spatial - rooms, audio, video, multiple screens - policing, wizards, mediation - effective telecommuting - need the richness of real world markets...people can sell to others + Is there a set of rules or basic ideas which can form the basis of a powerfully replicable system? - this would allow franchises to be disctrubed around the world - networks of servers? distinction between server and client fades... - money, commercialization? - Joule language 3.4.16. "Is personal privacy the main interest of Cypherpunks?" - Ensuring the _right_ and the _technological feasibility_ is more of the focus. This often comes up in two contexts: - 1. Charges of hypocrisy because people either use pseudonyms or, paradoxically, that they _don't_ use pseudonyms, digital signatures 3.4.17. "Shouldn't crypto be regulated?" - Many people make comparisons to the regulation of automobiles, of the radio spectrum, and even of guns. The comparison of crypto to guns is especially easy to make, and especially dangerous. - + A better comparison is "use of crypto = right to speak as you wish." - That is, we cannot demand that people speak in a language or form that is easily understandable by eavesdroppers, wiretappers, and spies. + If I choose to speak to my friends in Latvian, or in Elihiuish, or in - triple DES, that's my business. (Times of true war, as in World War - II, may be slightly different. As a libertarian, I'm not advocating - that, but I understand the idea that in times of war speaking in code + is suspect. We are not in a time of war, and haven't been.) - - Should we have "speech permits"? After all, isn't the regulation of + speech consistent with the regulation of automobiles? - - I did a satirical essay along these lines a while back. I won't - included it here, though. (My speech permit for satire expired and I + haven't had time to get it renewed.) - - In closing, the whole comparison of cryptography to armaments is - misleading. Speaking or writing in forms not readily understandable to - your enemies, your neighbors, your spouse, the cops, or your local - eavesdropper is as old as humanity. 3.4.18. Emphasize the "voluntary" nature of crypto + those that don't want privacy, can choose not to use crypto - just as they can take the locks of their doors, install wiretaps on their phones, remove their curtains so as not to interfere with peeping toms and police surveillance teams, etc. - as PRZ puts it, they can write all their letters on postcards, because they have "nothing to hide" - what we want to make sure doesn't happen is _others_ insisting that we cannot use crypto to maintain our own privacy + "But what if criminals have access to crypto and can keep secrets?" - this comes up over and over again - does this mean locks should not exist, or.....? 3.4.19. "Are most Cypherpunks anarchists?" - Many are, but probably not most. The term "anarchy" is often misunderstood. - As Perry Metzger puts it "Now, it happpens that I am an anarchist, but that isn't what most people associated with the term "cypherpunk" believe in, and it isn't fair to paint them that way -- hell, many people on this mailing list are overtly hostile to anarchism." [P.M., 1994-07-01] - comments of Sherry Mayo, others - But the libertarian streak is undeniably strong. And libertarians who think about the failure of politics and the implications of cryptgraphy generally come to the anarcho-capitalist or crypto-anarchist point of view. - In any case, the "other side" has not been very vocal in espousing a consistent ideology that combines strong crypto and things like welfare, entitlements, and high tax rates. (I am not condemning them. Most of my leftist friends turn out to believe in roughly the same things I believe in...they just attach different labels and have negative reactions to words like "capitalist.") 3.4.20. "Why is there so much ranting on the list?" - Arguments go on and on, points get made dozens of times, flaming escalates. This has gotten to be more of a problem in recent months. (Not counting the spikes when Detweiler was around.) + Several reasons: + the arguments are often matters of opinion, not fact, and hence people just keep repeating their arguments - made worse by the fact that many people are too lazy to do off-line reading, to learn about what they are expressing an opinion on - since nothing ever gets resolved, decided, vote upon, etc., the debates continue - since anyone is free to speak up at any time, some people will keep making the same points over and over again, hoping to win through repetition (I guess) + since people usually don't personally know the other members of the list, this promotes ranting (I've noticed that the people who know each other, such as the Bay Area folks, tend not to be as rude to each other...any sociologist or psychologist would know why this is so immediately). + the worst ranters tend to be the people who are most isolated from the other members of the list community; this is generally a well-known phenomenon of the Net - and is yet more reason for regional Cypherpunks groups to occasionally meet, to at least make some social and conversational connections with folks in their region. - on the other hand, rudeness is often warranted; people who assault me and otherwise plan to deprive me of my property of deserving of death, not just insults [Don't be worried, there are only a handful of people on this list I would be happy to see dead, and on none of them would I expend the $5000 it might take to buy a contract. Of course, rates could drop.] 3.4.21. The "rejectionist" stance so many Cypherpunks have - that compromise rarely helps when very basic issues are involved - the experience with the NRA trying compromise, only to find ever-more-repressive laws passed - the debacle with the EFF and their "EFF Digital Telephony Bill" ("We couldn't have put this bill together without your help") shows the corruption of power; I'm ashamed to have ever been a member of the EFF, and will of course not be renewing my membership. - I have jokingly suggested we need a "Popular Front for the Liberation of Crypto," by analogy with the PFLP. 3.4.22. "Is the Cypherpunks group an illegal or seditious organization?" - Well, there are those "Cypherpunk Criminal" t-shirts a lot of us have... - Depends on what country you're in. - Probably in a couple of dozen countries, membership would be frowned on - the material may be illegal in other countries - and many of us advocate things like using strong crypto to avoid and evade tzxes, to bypass laws we dislike, etc. 3.5. Self-organizing Nature of Cypherpunks 3.5.1. Contrary to what people sometimes claim, there is no ruling clique of Cypherpunks. Anybody is free to do nearly anything, just not free to commit others to course of action, or control the machine resources the list now runs on, or claim to speak for the "Cypherpunks" as a group (and this last point is unenforceable except through reptutation and social repercussions). 3.5.2. Another reason to be glad there is no formal Cypherpunks structure, ruling body, etc., is that there is then no direct target for lawsuits, ITAR vioalation charges, defamation or copyright infringement claims, etc. 3.6. Mechanics of the List 3.6.1. Archives of the Cyperpunks List - Karl Barrus has a selection of posts at the site chaos.bsu.edu, available via gopher. Look in the "Cypherpunks gopher site" directory. 3.6.2. "Why isn't the list sent out in encrypted form?" - Too much hassle, no additional security, would only make people jump through extra hoops (which might be useful, but probably not worth the extra hassle and ill feelings). - "We did this about 8 years ago at E&S using DEC VMS NOTES. We used a plain vanilla secret key algorithm and a key shared by all legitimate members of the group. We could do it today -- but why bother? If you have a key that widespread, it's effectively certain that a "wrong person" (however you define him/her) will have a copy of the key." [Carl Ellison, Encrypted BBS?, 1993-08-02] 3.6.3. "Why isn't the list moderated?" - This usually comes up during severe flaming episodes, notably when Detweiler is on the list in one of his various personnas. Recently, it has not come up, as things have been relatively quiet. + Moderation will *not* happen - nobody has the time it takes - nobody wants the onus + hardly consistent with many of our anarchist leanings, is it? - (Technically, moderation can be viewed as "my house, my rules, and hence OK, but I think you get my point.) - "No, please let's not become a 'moderated' newsgroup. This would be the end of freedom! This is similar to giving the police more powers because crime is up. While it is a tactic to fight off the invaders, a better tactic is knowledge." [RWGreene@vnet.net, alt.gathering.rainbow, 1994- 07-06]" 3.6.4. "Why isn't the list split into smaller lists?" - What do you call the list outages? + Seriously, several proposals to split the list into pieces have resulted in not much - a hardware group...never seen again, that I know of - a "moderated cryptography" group, ditto - a DC-Net group...ditto - several regional groups and meeting planning groups, which are apparently moribund - a "Dig Lib" group...ditto - use Rishab's comment: + Reasons are clear: one large group is more successful in traffic than smaller, low-volume groups...out of sight, out of mind - and topics change anyway, so the need for a "steganography" mailing list (argued vehemently for by one person, not Romana M., by the way) fades away when the debate shifts. And so on. 3.6.5. Critical Addresses, Numbers, etc. + Cypherpunks archives sites - soda - mirror sites - ftp sites - PGP locations - Infobot at Wired - majordomo@toad.com; "help" as message body 3.6.6. "How did the Cypherpunk remailers appear so quickly?" - remailers were the first big win...a weekend of Perl hacking 3.7. Publicity 3.7.1. "What kind of press coverage have the Cypherpunks gotten?" - " I concur with those who suggest that the solution to the ignorance manifested in many of the articles concerning the Net is education. The coverage of the Cypherpunks of late (at least in the Times) shows me that reasonable accuracy is possible." [Chris Walsh, news.admin.policy, 1994-07-04] 3.8. Loose Ends 3.8.1. On extending the scope of Cypherpunks to other countres - a kind of crypto underground, to spread crypto tools, to help sow discord, to undermine corrupt governments (to my mind, all governments now on the planet are intrinsically corrupt and need to be undermined) - links to the criminal underworlds of these countries is one gutsy thing to consider....fraught with dangers, but ultimately destabilizing of governments 4. Goals and Ideology -- Privacy, Freedom, New Approaches 4.1. copyright THE CYPHERNOMICON: Cypherpunks FAQ and More, Version 0.666, 1994-09-10, Copyright Timothy C. May. All rights reserved. See the detailed disclaimer. Use short sections under "fair use" provisions, with appropriate credit, but don't put your name on my words. 4.2. SUMMARY: Goals and Ideology -- Privacy, Freedom, New Approaches 4.2.1. Main Points 4.2.2. Connections to Other Sections - Crypto Anarchy is the logical outgrowth of strong crypto. 4.2.3. Where to Find Additional Information - Vernor Vinge's "True Names" - David Friedman's "Machinery of Freedom" 4.2.4. Miscellaneous Comments - Most of the list members are libertarians, or leaning in that direction, so the bias toward this is apparent. - (If there's a coherent _non_-libertarian ideology, that's also consistent with supporting strong crypto, I'm not sure it's been presented.) 4.3. Why a Statement of Ideology? 4.3.1. This is perhaps a controversial area. So why include it? The main reason is to provide some grounding for the later comments on many issues. 4.3.2. People should not expect a uniform ideology on this list. Some of us are anarcho-capitalist radicals (or "crypto anarchists"), others of us are staid Republicans, and still others are Wobblies and other assored leftists. 4.4. "Welcome to Cypherpunks" 4.4.1. This is the message each new subscriber to the Cypherpunks lists gets, by Eric Hughes: 4.4.2. "Cypherpunks assume privacy is a good thing and wish there were more of it. Cypherpunks acknowledge that those who want privacy must create it for themselves and not expect governments, corporations, or other large, faceless organizations to grant them privacy out of beneficence. Cypherpunks know that people have been creating their own privacy for centuries with whispers, envelopes, closed doors, and couriers. Cypherpunks do not seek to prevent other people from speaking about their experiences or their opinions. "The most important means to the defense of privacy is encryption. To encrypt is to indicate the desire for privacy. But to encrypt with weak cryptography is to indicate not too much desire for privacy. Cypherpunks hope that all people desiring privacy will learn how best to defend it. "Cypherpunks are therefore devoted to cryptography. Cypherpunks wish to learn about it, to teach it, to implement it, and to make more of it. Cypherpunks know that cryptographic protocols make social structures. Cypherpunks know how to attack a system and how to defend it. Cypherpunks know just how hard it is to make good cryptosystems. "Cypherpunks love to practice. They love to play with public key cryptography. They love to play with anonymous and pseudonymous mail forwarding and delivery. They love to play with DC-nets. They love to play with secure communications of all kinds. "Cypherpunks write code. They know that someone has to write code to defend privacy, and since it's their privacy, they're going to write it. Cypherpunks publish their code so that their fellow cypherpunks may practice and play with it. Cypherpunks realize that security is not built in a day and are patient with incremental progress. "Cypherpunks don't care if you don't like the software they write. Cypherpunks know that software can't be destroyed. Cypherpunks know that a widely dispersed system can't be shut down. "Cypherpunks will make the networks safe for privacy." [Eric Hughes, 1993-07-21 version] 4.5. "Cypherpunks Write Code" 4.5.1. "Cypherpunks write code" is almost our mantra. 4.5.2. This has come to be a defining statement. Eric Hughes used it to mean that Cypherpunks place more importance in actually changing things, in actually getting working code out, than in merely talking about how things "ought" to be. - Eric Hughes statement needed here: - Karl Kleinpaste, author of one of the early anonymous posting services (Charcoal) said this about some proposal made: "If you've got serious plans for how to implement such a thing, please implement it at least skeletally and deploy it. Proof by example, watching such a system in action, is far better than pontification about it." [Karl_Kleinpaste@cs.cmu.edu, news.admin.policy, 1994-06-30] 4.5.3. "The admonition, "Cypherpunks write code," should be taken metaphorically. I think "to write code" means to take unilateral effective action as an individual. That may mean writing actual code, but it could also mean dumpster diving at Mycrotronx and anonymously releasing the recovered information. It could also mean creating an offshore digital bank. Don't get too literal on us here. What is important is that Cypherpunks take personal responsibility for empowering themselves against threats to privacy." [Sandy Sandfort, 1994-07-08] 4.5.4. A Cypherpunks outlook: taking the abstractions of academic conferences and making them concrete - One thing Eric Hughes and I discussed at length (for 3 days of nearly nonstop talk, in May, 1992) was the glacial rate of progress in converting the cryptographic primitive operations of the academic crypto conferences into actual, workable code. The basic RSA algorithm was by then barely available, more than 15 years after invention. (This was before PGP 2.0, and PGP 1.0 was barely available and was disappointing, with RSA Data Security's various products in limited niches.) All the neat stuff on digital cash, DC- Nets, bit commitment, olivioius transfer, digital mixes, and so on, was completely absent, in terms of avialable code or "crypto ICs" (to borrow Brad Cox's phrase). If it took 10-15 years for RSA to really appear in the real world, how long would it take some of the exciting stuff to get out? - We thought it would be a neat idea to find ways to reify these things, to get actual running code. As it happened, PGP 2.0 appeared the week of our very first meeting, and both the Kleinpaste/Julf and Cypherpunks remailers were quick, if incomplete, implementations of David Chaum's 1981 "digital mixes." (Right on schedule, 11 years later.) - Sadly, most of the abstractions of cryptology remain residents of academic space, with no (available) implementations in the real world. (To be sure, I suspect many people have cobbled-together versions of many of these things, in C code, whatever. But their work is more like building sand castles, to be lost when they graduate or move on to other projects. This is of course not a problem unique to cryptology.) - Today, various toolkits and libraries are under development. Henry Strickland (Strick) is working on a toolkit based on John Ousterhout's "TCL" system (for Unix), and of course RSADSI provides RSAREF. Pr0duct Cypher has "PGP Tools." Other projects are underway. (My own longterm interest here is in building objects which act as the cryptography papers would have them act...building block objects. For this, I'm looking at Smalltalk of some flavor.) - It is still the case that most of the modern crypto papers discuss theoretical abstractions that are _not even close_ to being implemented as reusable, robust objects or routines. Closing the gap between theoretical papers and practical realization is a major Cypherpunk emphasis. 4.5.5. Prototypes, even if fatally flawed, allow for evolutionary learning and improvement. Think of it as engineering in action. 4.6. Technological empowerment 4.6.1. (more needed here....) 4.6.2. As Sandy Sandfort notes, "The real point of Cypherpunks is that it's better to use strong crypto than weak crypto or no crypto at all. Our use of crypto doesn't have to be totally bullet proof to be of value. Let *them* worry about the technicalities while we make sure they have to work harder and pay more for our encrypted info than they would if it were in plaintext." [S.S. 1994-07-01] 4.7. Free Speech Issues 4.7.1. Speech - "Public speech is not a series of public speeches, but rather one's own words spoken openly and without shame....I desire a society where all may speak freely about whatever topic they will. I desire that all people might be able to choose to whom they wish to speak and to whom they do not wish to speak. I desire a society where all people may have an assurance that their words are directed only at those to whom they wish. Therefore I oppose all efforts by governments to eavesdrop and to become unwanted listeners." [Eric Hughes, 1994-02-22] - "The government has no right to restrict my use of cryptography in any way. They may not forbid me to use whatever ciphers I may like, nor may they require me to use any that I do not like." [Eric Hughes, 1993-06-01] 4.7.2. "Should there be _any_ limits whatsoever on a person's use of cryptography?" - No. Using the mathematics of cryptography is merely the manipulation of symbols. No crime is involved, ipso facto. - Also, as Eric Hughes has pointed out, this is another of those questions where the normative "should" or "shouldn't" invokes "the policeman inside." A better way to look at is to see what steps people can take to make any question of "should" this be allowed just moot. - The "crimes" are actual physical acts like murder and kidnapping. The fact that crypto may be used by plotters and planners, thus making detection more difficult, is in no way different from the possibility that plotters may speak in an unusual language to each other (ciphers), or meet in a private home (security), or speak in a soft voice when in public (steganography). None of these things should be illegal, and *none of them would be enforceable* except in the most rigid of police states (and probably not even there). - "Crypto is thoughtcrime" is the effect of restricting cryptography use. 4.7.3. Democracy and censorship - Does a community have the right to decide what newsgroups or magazines it allows in its community? Does a nation have the right to do the same? (Tennessee, Iraq, Iran, France. Utah?) - This is what bypasses with crypto are all about: taking these majoritarian morality decisions out of the hands of the bluenoses. Direct action to secure freedoms. 4.8. Privacy Issues 4.8.1. "Is there an agenda here beyond just ensuring privacy?" - Definitely! I think I can safely say that for nearly all political persuasions on the Cypherpunks list. Left, right, libertarian, or anarchist, there's much more to to strong crypto than simple privacy. Privacy qua privacy is fairly uninteresting. If all one wants is privacy, one can simply keep to one's self, stay off high-visibility lists like this, and generally stay out of trouble. - Many of us see strong crypto as the key enabling technology for a new economic and social system, a system which will develop as cyberspace becomes more important. A system which dispenses with national boundaries, which is based on voluntary (even if anonymous) free trade. At issue is the end of governments as we know them today. (Look at interactions on the Net--on this list, for example--and you'll see many so-called nationalities, voluntary interaction, and the almost complete absence of any "laws." Aside from their being almost no rules per se for the Cypherpunks list, there are essentially no national laws that are invokable in any way. This is a fast-growing trend.) + Motivations for Cypherpunks - Privacy. If maintaining privacy is the main goal, there's not much more to say. Keep a low profile, protect data, avoid giving out personal information, limit the number of bank loans and credit applications, pay cash often, etc. - Privacy in activism. + New Structures. Using cryptographic constructs to build new political, economic, and even social structures. - Political: Voting, polling, information access, whistleblowing - Economic: Free markets, information markets, increased liquidity, black markets - Social: Cyberspatial communities, True Names - Publically inspectable algorithms always win out over private, secret algorithms 4.8.2. "What is the American attitude toward privacy and encryption?" + There are two distinct (and perhaps simultaneously held) views that have long been found in the American psyche: - "A man's home is his castle." "Mind your own business." The frontier and Calvinist sprit of keeping one's business to one's self. - "What have you got to hide?" The nosiness of busybodies, gossiping about what others are doing, and being suspicious of those who try too hard to hide what they are doing. + The American attitude currently seems to favor privacy over police powers, as evidenced by a Time-CNN poll: - "In a Time/CNN poll of 1,000 Americans conducted last week by Yankelovich Partners, two-thirds said it was more important to protect the privacy of phone calls than to preserve the ability of police to conduct wiretaps. When informed about the Clipper Chip, 80% said they opposed it." [Philip Elmer-Dewitt, "Who Should Keep the Keys," _TIME_, 1994-03-04.] - The answer given is clearly a function of how the question is phrased. Ask folks if they favor "unbreakable encryption" or "fortress capabilities" for terrorists, pedophiles, and other malefactors, and they'll likely give a quite different answer. It is this tack now being taken by the Clipper folks. Watch out for this! - Me, I have no doubts. - As Perry Metzger puts it, "I find the recent disclosures concerning U.S. Government testing of the effects of radiation on unknowing human subjects to be yet more evidence that you simply cannot trust the government with your own personal safety. Some people, given positions of power, will naturally abuse those positions, often even if such abuse could cause severe injury or death. I see little reason, therefore, to simply "trust" the U.S. government -- and given that the U.S. government is about as good as they get, its obvious that NO government deserves the blind trust of its citizens. "Trust us, we will protect you" rings quite hollow in the face of historical evidence. Citizens must protect and preserve their own privacy -- the government and its centralized cryptographic schemes emphatically cannot be trusted." [P.M., 1994-01-01] 4.8.3. "How is 1994 like 1984?" - The television ad for Clipper: "Clipper--why 1994 _will_ be like 1984" + As Mike Ingle puts it: - 1994: Wiretapping is privacy Secrecy is openness Obscurity is security 4.8.4. "We anticipate that computer networks will play a more and more important role in many parts of our lives. But this increased computerization brings tremendous dangers for infringing privacy. Cypherpunks seek to put into place structures which will allow people to preserve their privacy if they choose. No one will be forced to use pseudonyms or post anonymously. But it should be a matter of choice how much information a person chooses to reveal about himself when he communicates. Right now, the nets don't give you that much choice. We are trying to give this power to people." [Hal Finney, 1993-02-23] 4.8.5. "If cypherpunks contribute nothing else we can create a real privacy advocacy group, advocating means of real self- empowerment, from crypto to nom de guerre credit cards, instead of advocating further invasions of our privacy as the so-called privacy advocates are now doing!" [Jim Hart, 1994- 09-08] 4.9. Education Issues 4.9.1. "How can we get more people to use crypto?" - telling them about the themes of Cypherpunks - surveillance, wiretapping, Digital Telephony, Clipper, NSA, FinCEN, etc....these things tend to scare a lot of folks - making PGP easier to use, better integration with mailers, etc. - (To be frank, convincing others to protect themselves is not one of my highest priorities. Then why have I written this megabyte-plus FAQ? Good question. Getting more users is a general win, for obvious reasons.) 4.9.2. "Who needs to encrypt?" + Corporations - competitors...fax transmissions + foreign governments - Chobetsu, GCHQ, SDECE, Mossad, KGB + their own government - NSA intercepts of plans, investments + Activist Groups - Aryan Nation needs to encrypt, as FBI has announced their intent to infiltrate and subvert this group - RU-486 networks - Amnesty International + Terrorists and Drug Dealers - clearly are clueless at times (Pablo Escobar using a cellphone!) - Triads, Russian Mafia, many are becoming crypto-literate - (I've been appoached-'nuff said) + Doctors, lawyers, psychiatrists, etc. - to preserve records against theft, snooping, casual examination, etc. - in many cases, a legal obligation has been attached to this (notably, medical records) - the curious situation that many people are essentially _required_ to encrypt (no other way to ensure standards are met) and yet various laws exists to limit encryption...ITAR, Clipper, EES - (Clipper is a partial answer, if unsatisfactory) 4.9.3. "When should crypto be used?" - It's an economic matter. Each person has to decide when to use it, and how. Me, I dislike having to download messages to my home machine before I can read them. Others use it routinely. 4.10. Libertarian Issues 4.10.1. A technological approach to freedom and privacy: - "Freedom is, practically, given as much (or more) by the tools we can build to protect it, as it is by our ability to convince others who violently disagree with us not to attack us. On the Internet we have tools like anon remailers and PGP that give us a great deal of freedom from coercion even in the midst of censors. Thus, these tools piss off fans of centralized information control, the defenders of the status quo, like nothing else on the Internet." [<an50@desert.hacktic.nl> (Nobody), libtech- l@netcom.com, 1994-06-08] + Duncan Frissell, as usual, put it cogently: - "If I withhold my capital from some country or enterprise I am not threatening to kill anyone. When a "Democratic State" decides to do something, it does so with armed men. If you don't obey, they tend to shoot....[I]f technological change enhances the powers of individuals, their power is enhanced no matter what the government does. "If the collective is weakened and the individual strengthened by the fact that I have the power of cheap guns, cars, computers, telecoms, and crypto then the collective has been weakened and we should ease the transition to a society based on voluntary rather than coerced interaction. "Unless you can figure out a new, improved way of controlling others; you have no choice." [D.F., Decline and Fall, 1994-06-19] 4.10.2. "They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety." [Benjamin Franklin] 4.10.3. a typical view of government - "As I see it, it's always a home for bullies masquerading as a collective defense. Sometimes it actually it actually has to perform its advertised defense function. Like naked quarks, purely defensive governments cannot exist. They are bipolar by nature, with some poles (i.e., the bullying part) being "more equal than others." [Sandy Sandfort, 1994- 09-06] 4.10.4. Sadly, several of our speculative scenarios for various laws have come to pass. Even several of my own, such as: - "(Yet Another May Prediction Realized)...The text of a "digital stalking bill" was just sent to Cyberia-l." [L. Todd Masco, 1994-08-31] (This was a joking prediction I made that "digital stalking" would soon be a crime; there had been news articles about the horrors of such cyberspatial stalkings, regardless of there being no real physical threats, so this move is not all that surprising. Not surprising in an age when free speech gets outlawed as "assault speech.") 4.10.5. "Don't tread on me." 4.10.6. However, it's easy to get too negative on the situation, to assume that a socialist state is right around the corner. Or that a new Hitler will come to power. These are unlikely developments, and not only because of strong crypto. Financial markets are putting constraints on how fascist a government can get...the international bond markets, for example, will quickly react to signs like this. (This is the theory, at least.) 4.10.7. Locality of reference, cash, TANSTAAFL, privacy - closure, local computation, local benefits - no accounting system needed - markets clear - market distortions like rationing, coupons, quotas, all require centralized record-keeping - anything that ties economic transactions to identity (rationing, entitlements, insurance) implies identity- tracking, credentials, etc. + Nonlocality also dramatically increases the opportunities for fraud, for scams and con jobs - because something is being promised for future delivery (the essence of many scams) and is not verifiable locally - because "trust" is invoked - Locality also fixes the "policeman inside" problem: the costs of decisions are borne by the decider, not by others. 4.11. Crypto Anarchy 4.11.1. The Crypto Anarchy Principle: Strong crypto permits unbreakable encrypion, unforgeable signatures, untraceable electronic messages, and unlinkable pseudonomous identities. This ensures that some transactions and communications can be entered into only voluntarily. External force, law, and regulation cannot be applied. This is "anarchy," in the sense of no outside rulers and laws. Voluntary arrangements, back- stopped by voluntarily-arranged institutions like escrow services, will be the only form of rule. This is "crypto anarchy." 4.11.2. crypto allows a return to contracts that governments cannot breach - based on reputation, repeat business - example: ordering illegal material untraceably and anonymously,,,governments are powerless to do anything - private spaces, with the privacy enforced via cryptographic permissions (access credentials) - escrows (bonds) 4.11.3. Technological solutions over legalistic regulations + Marc Ringuette summarized things nicely: - "What we're after is some "community standards" for cyberspace, and what I'm suggesting is the fairly libertarian standard that goes like this: " Prefer technological solutions and self-protection solutions over rule-making, where they are feasible. "This is based on the notion that the more rules there are, the more people will call for the "net police" to enforce them. If we can encourage community standards which emphasize a prudent level of self-protection, then we'll be able to make do with fewer rules and a less intrusive level of policing."[Marc Ringuette, 1993-03-14] + Hal Finney has made cogent arguments as to why we should not become too complacent about the role of technology vis- a-vis politics. He warns us not to grow to confident: - "Fundamentally, I believe we will have the kind of society that most people want. If we want freedom and privacy, we must persuade others that these are worth having. There are no shortcuts. Withdrawing into technology is like pulling the blankets over your head. It feels good for a while, until reality catches up. The next Clipper or Digital Telephony proposal will provide a rude awakening." [Hal Finney, POLI: Politics vs Technology, 1994-01-02] - "The idea here is that the ultimate solution to the low signal-to-noise ratio on the nets is not a matter of forcing people to "stand behind their words". People can stand behind all kinds of idiotic ideas. Rather, there will need to be developed better systems for filtering news and mail, for developing "digital reputations" which can be stamped on one's postings to pass through these smart filters, and even applying these reputations to pseudonyms. In such a system, the fact that someone is posting or mailing pseudonymously is not a problem, since nuisance posters won't be able to get through." [Hal Finney, 1993- 02-23] 4.11.4. Reputations 4.11.5. I have a moral outlook that many will find unacceptable or repugnant. To cut to the chase: I support the killing of those who break contracts, who steal in serious enough ways, and who otherwise commit what I think of as crimes. + I don't mean this abstractly. Here's an example: - Someone is carrying drugs. He knows what he's involved in. He knows that theft is punishable by death. And yet he steals some of the merchandise. - Dealers understand that they cannot tolerate this, that an example must be made, else all of their employees will steal. - Understand that I'm not talking about the state doing the killing, nor would I do the killing. I'm just saying such things are the natural enforcement mechanism for such markets. Realpolitik. - (A meta point: the drug laws makes things this way. Legalize all drugs and the businesses would be more like "ordinary" businesses.) - In my highly personal opinion, many people, including most Congressrodents, have committed crimes that earn them the death penalty; I will not be sorry to see anonymous assassination markets used to deal with them. 4.11.6. Increased espionage will help to destroy nation-state-empires like the U.S., which has gotten far too bloated and far too dependent on throwing its weight around; nuclear "terrorism" may knock out a few cities, but this may be a small price to pay to undermine totally the socialist welfare states that have launched so many wars this century. 4.12. Loose Ends 4.12.1. "Why take a "no compromise" stance?" - Compromise often ends up in the death of a thousand cuts. Better to just take a rejectionist stance. - The National Rifle Association (NRA) learned this lesson the hard way. EFF may eventually learn it; right now they appear to be in the "coopted by the power center" mode, luxuriating in their inside-the-Beltway access to the Veep, their flights on Air Force One, and their general schmoozing with the movers and shakers...getting along by going along. - Let's not compromise on basic issues. Treat censorship as a problem to be routed around (as John Gilmore suggests), not as something that needs to be compromised on. (This is directed at rumblings about how the Net needs to "police itself," by the "reasonable" censorship of offensive posts, by the "moderation" of newsgroups, etc. What should concern us is the accomodation of this view by well-meaning civil liberties groups, which are apparently willing to play a role in this "self-policing" system. No thanks.) - (And since people often misunderstand this point, I'm not saying private companies can't set whatever policies they wish, that moderated newsgroups can't be formed, etc. Private arrangements are just that. The issue is when censorship is forced on those who have no other obligations. Government usually does this, often aided and abetted by corporations and lobbying groups. This is what we need to fight. Fight by routing around, via technology.) 4.12.2. The inherent evils of democracy - To be blunt about it, I've come to despise the modern version of democracy we have. Every issue is framed in terms of popular sentiment, in terms of how the public would vote. Mob rule at its worst. - Should people be allowed to wear blue jeans? Put it to a vote. Can employers have a policy on blue jeans? Pass a law. Should health care be provided to all? Put it to a vote. And so on, whittling away basic freedoms and rights. A travesty. The tyranny of the majority. - De Toqueville warned of this when he said that the American experiment in democracy would last only until citizens discovered they could pick the pockets of their neighbors at the ballot box. - But maybe we can stop this nonsense. I support strong crypto (and its eventual form, crypto anarchy) because it undermines this form of democracy. It takes some (and perhaps many) transactions out of the realm of popularity contests, beyond the reach of will of the herd. (No, I am not arguing there will be a complete phase change. As the saying goes, "You can't eat cyberspace." But a lot of consulting, technical work, programming, etc., can in fact be done with crypto anarchic methods, with the money gained transferred in a variety of ways into the "real world." More on this elsewhere.) + Crypto anarchy effectively allows people to pick and choose which laws they support, at least in cyberspatial contexts. It empowers people to break the local bonds of their majoritarian normative systems and decide for themselves which laws are moral and which are bullshit. - I happen to have faith that most people will settle on a relatively small number of laws that they'll (mostly) support, a kind of Schelling point in legal space. 4.12.3. "Is the Cypherpunks agenda _too extreme_?" - Bear in mind that most of the "Cypherpunks agenda," to the extent we can identify it, is likely to provoke ordinary citizens into _outrage_. Talk of anonymous mail, digital money, money laundering, information markets, data havens, undermining authority, transnationalism, and all the rest (insert your favorite idea) is not exactly mainstream. 4.12.4. "Crypto Anarchy sounds too wild for me." - I accept that many people will find the implications of crypto anarchy (which follows in turn from the existence of strong cryptography, via the Crypto Anarchy Principle) to be more than they can accept. - This is OK (not that you need my OK!). The house of Cypherpunks has many rooms. 5. Cryptology 5.1. copyright THE CYPHERNOMICON: Cypherpunks FAQ and More, Version 0.666, 1994-09-10, Copyright Timothy C. May. All rights reserved. See the detailed disclaimer. Use short sections under "fair use" provisions, with appropriate credit, but don't put your name on my words. 5.2. SUMMARY: Cryptology 5.2.1. Main Points - gaps still exist here...I treated this as fairly low priority, given the wealth of material on cryptography 5.2.2. Connections to Other Sections - detailed crypto knowledge is not needed to understand many of the implications, but it helps to know the basics (it heads off many of the most wrong-headed interpretations) - in particular, everyone should learn enough to at least vaguely understand how "blinding" works 5.2.3. Where to Find Additional Information + a dozen or so major books - Schneier, "Applied Cryptography"--is practically "required reading" - Denning - Brassard - Simmons - Welsh, Dominic - Salomaa - "CRYPTO" Proceedings - Other books I can take or leave - many ftp sites, detailed in various places in this doc - sci.crypt, alt.privacy.pgp, etc. - sci.crypt.research is a new group, and is moderated, so it should have some high-quality, technical posts - FAQs on sci.crypt, from RSA, etc. - Dave Banisar of EPIC (Electronic Privacy Information Center) reports: "...we have several hundred files on encryption available via ftp/wais/gopher/WWW from cpsr.org /cpsr/privacy/crypto." [D.B., sci.crypt, 1994-06-30] 5.2.4. Miscellaneous Comments - details of algorithms would fill several books...and do - hence, will not cover crypto in depth here (the main focus of this doc is the implications of crypto, the Cypherpunkian aspects, the things not covered in crypto textbooks) - beware of getting lost in the minutiae, in the details of specific algorithms...try to keep in the mind the _important_ aspects of any system 5.3. What this FAQ Section Will Not Cover 5.3.1. Why a section on crypto when so many other sources exist? - A good question. I'll be keeping this section brief, as many textbooks can afford to do a much better job here than I can. - not just for those who read number theory books with one hand 5.3.2. NOTE: This section may remain disorganized, at least as compared to some of the later sections. Many excellent sources on crypto exist, including readily available FAQs (sci.crypt, RSADSI FAQ) and books. Schneier's books is especially recommended, and should be on _every_ Cypherpunk's bookshelf. 5.4. Crypto Basics 5.4.1. "What is cryptology?" - we see crypto all around us...the keys in our pockets, the signatures on our driver's licenses and other cards, the photo IDs, the credit cards + cryptography or cryptology, the science of secret writing...but it's a lot more...consider I.D. cards, locks on doors, combinations to safes, private information...secrecy is all around us - some say this is bad--the tension between "what have you got to hide?" and "none of your business" - some exotic stuff: digital money, voting systems, advanced software protocols - of importance to protecting privacy in a world of localizers (a la Bob and Cherie), credit cards, tags on cars, etc....the dossier society + general comments on cryptography - chain is only as strong as its weakest link - assume opponnent knows everything except the secret key - - Crypto is about economics + Codes and Ciphers + Simple Codes - Code Books + Simple Ciphers + Substitution Ciphers (A=C, B=D, etc.) - Caesar Shift (blocks) + Keyword Ciphers
