However, almost all Internet protocols are TCP/IP based. The receiver of a TCP connection can choose not to accept the connection, or to drop it at any time. The window protocol keeps the sender from transmitting faster than any part of the connection can manage. (How do you think ftp transfers between sites with disparate connection speeds would work otherwise?) One could theoretically have a package that sprayed UDP packets at a particular IP address, or even have a modified TCP that ignored disconnects. I think most service providers would regard using such code as being on a par with running a program that tried to telnet sequentially to all known IP addresses, trying common passwords on each. -- Richard Parratt

Known data havens for pirates? Doubtful

I forget who wrote: > blame them. Copyrighted data on a server in a jurisdiction that > doesn't acknowledege the copyrights - a prime use for Data Havens > when they come of age. I suppose you _are_ aware that the US has threatened China with punitive duties on $100 BILLION dollars worth of trade, and that China has started holding some show trials (without shutting down its state-owned CD-piracy factories). It's not going to be easy to find a country more willing and able to ignore international copyright law (Berne Convention etc) than China; however, despite howls of protest even China is likely to knuckle down eventually. What may be likely is distributed piracy markets, such as described in Tim's BlackNet spoof.

OK, let's ponder the minimum hardware necessary, possible minimal configuration (Intel/clone based): (1) Case. (2) Power supply. (3) Motherboard/CPU and 4mb RAM. (4) Hard drive w/ controller. (5) modem card. (5) No monitor, keyboard, floppy, or video card. (a) would require some "umbilical cord" connection to initially set up from another PC. (b) need to operate on "umbilical", direct and uucp modes. I am just thinking out loud here, but the hardware could be damn cheap (sub $500). You can find old 386 boards with 4mb right on the board (no SIMMs) for next to nothing (the decreasing popularity of 30-pin SIMMs makes this a surplus store reality, as nobody wants to bother to strip out the RAM chips anymore). I have also seen an ad by the KILA company in Boulder, CO who advertise some sort of compact pc-on-a-card deal, that might be applicable.

That $10K would go a long way to getting PGP Phone finished. ... I'm not sure how encryption chages the equation if that van on the street can read the data off your screen and/or printer. Just as cryptanalysis is a necessary component of good cryptography, some sort of VanEck analysis would seem to be required in order to evaluate the utility of methods to block it. What exactly would one need to do to block Van Eck monitoring? I've seen computer rooms that were completely lined with copper sheathing. Is it really necessary to go to that extent? Will aluminum foil and power line conditioning handle it? You can't really tell how effective counter-measures are unless you have some way to see what reduction in emitted signal they provide. --Paul J. Ste.

The Remailer Crisis
by tcmay＠netcom.com 17 Dec '03

17 Dec '03

I don't think I've used "crisis" in a thread I started, so this tells you what I think. The remailers are stagnating, only very slowly adding important features, and the number is not growing...in fact, it's been shrinking. This, as the remailers are under attack. Editorialists are railing against the dangers of anonymity and remailers, and the "Church of Scientology" is threatening lawsuits against remailer operators unless they block certain newsgroups. (Lots of issues, clever workarounds proposed, etc.) Now whether or not the Church of Scientology, or RSADSI (for the RC4 code remailing), or anyone else could legally _win_ such a case is not the issue. Not many remailer operators would be able to mount a defense...they are not, frankly, folks heros as Zimmermann is--and even PRZ is struggling to raise money. Maybe the EFF (ugh) would leap into the fray, but I doubt it. Nope, I fear that the pressures that have driven several remailers to halt operation are just the tip of the iceberg. (Some remailers have quit because of words from their sysadmins, semi-threatening conversations with Brad Templeton--Hi, Brad!--, and so on. Real letters from real lawyers would have a profoundly more chilling effect.) We've debated this stuff many times, but the numbers of remailers are shrinking. Raph Levien summarized the situation nicely in a post to alt.anon-server: "We're down to fifteen remailers now, many of which are unreliable. I would say the remailer net is not in good shape right now. Fortunately, I know of a number of plans to bring new remailers up, as well as restoring old ones." (I hope Raph can share with us soon what some of the plans are, unless he fears revealing this will aid our opponents.) I could see the whole remailer system imploding. A few threatening letters, especially if sent by real lawyers, could demolish the few U.S. sites. And with the Netherlands toying with proposals to ban or limit private encryption, having Holland as the main remaining host for remailers would be rather precarious. We need lots more remailers, in many more countries. What can be done? * We need to get the number of "solid" remailers up from the current dozen or so up into the _hundreds_. * I favor separating the "account that remails" from the "owner of the site," as I have argued in vain in the past. (Example: a willing site gives out or sells many accounts...each is legally separate, and each must be legally challenged. My longer posts dealt with this.) (The owner of the site/machine can take a "hands off" attitude toward what his customers are doing in their accounts. This doesn't stop pressures from being applied, but it slows them down, and (probably) better insulates the owner from legal charges.) * Traffic needs to be increased. Remailers should probably go to constant padding traffic, to do this. Exhorting end-users to use remailers more won't be enough. * More offshore sites are needed. So far, only Canada and the Netherlands are offshore hosts (and Canada is effectively part of the U.S.). Some sites in Russia would be dramatic. Ditto for Asia, South America, etc. * The whole issue of "remailer businesses," with all the usual issues of digital postage, stamps, coupons, etc, has to be resolved. That is, we need to get some movement here. Most remailers are run as projects by students on machines they don't control, or that they can be pressured on, or with a committment to stay in business that will evaporate too easily. A business, with business responsibilities, is usually a more stable solution. I think we need to set some rough targets and brainstorm on how to get to them. For example, the Linux mavens could tell us if Linux-based remailer boxes could be hung on dedicated connections to The Little Garden network, as a specific example. A "black box remailer" such as several folks have suggested (Chaum (in 1981), me, Eric Hughes, others) might be buildable for under a grand. We could ask here for contributions, and might even raise this amount of money. Then each of us who contributed could have "accounts," maybe several of them. Imagine 100 or more "remailers" all on this one machine--I'm deliberately ignoring the security issue for now. Little Garden has stated categorically that they will not tell users what they can or can't do with their machines (though I can think of some cases where they might have to, as with spamming, etc.). Anyway, you can see where I'm headed. My big fear is that the one really major achievement of the Cypherpunks group, the remailers, are not increasing in number and could be knocked out all too easily with some legal attacks. It's time to get cracking on this crisis. --Tim May -- .......................................................................... Timothy C.

Re: Abuse and Remailer Ethics

I would just hate it to have my >head on the plate of a remailer operator who takes an interest >in subtile ethical discussion of whether to sell me out or not. If you chain it through 3 or 4 remailers with PGP, then pretty much all 3 or 4 of them have got to decide to sell you out. I trust Julf a lot, but I'm not sure I trust him four times as much as much as every other remailer operator. Or something like that. You can also probably use penet as a link on your larger chain, although I've never tried this to see how it works. And I would note that the "subtle ethical discussion" seemed to consist of the operator trying to figure out what he should do in the future about this sort of thing, and he never even seemed to consider turning over the name of the anon user. Although he did acknowledge that in the future he might, or might work with other operators to try and discover a True Name. *shrug*

WHERE CAN I GET THE PGP VERSION DIRECTLY FROM PHILIP ZIMMERMANN? Get the MIT version. See http://web.mit.edu/network/pgp-form.html WHAT IS PGP 2.6.i? Stale Schumacher <staalesc(a)ifi.uio.no> released an international version of PGP built the "right way." By "right way," I mean that it uses the latest MIT code, but uses a different rsaglue.c to use the mpilib instead of RSAREF for RSA calculations, thus including all the latest bug fixes and features in the main freeware PGP code line, but frees non-USA persons from the limitations of the RSAREF license. This release has been as strongly endorsed by Philip Zimmermann as he can do without incriminating himself. Naturally, by not using the RSAREF code for RSA calculations, this version is not legal for use in the USA (other than limited research, etc.), but is fine anywhere else (like Canada) were RSA patents don't hold. Note that the latest version of Stale Schumacher's PGP is 2.6.i, 2.6i (without the second .) was a beta test version that has been superceded. WHAT IS PGP 2.6ui? The "unofficial international" versions are really just PGP 2.3a, modified just enough to make it compatible with MIT PGP 2.6, but do not include all of the fixes in MIT PGP 2.6 and MIT PGP 2.6.1. They have a "ui" somewhere in their file names. WHERE CAN I GET VIACRYPT PGP? Contact Viacrypt in Phoenix, Arizona, USA. The commecial version of PGP is fully licensed to use the patented RSA and IDEA encryption algorithms in commercial and government environments in the USA and Canada. It is fully compatible with, functionally the same as, and just as strong as the freeware version of PGP. Due to limitations on ViaCrypt's RSA distribution license, ViaCrypt only distributes executable code and documentation for it, but they are working on making PGP available for a variety of platforms. Call or write to them for the latest information. The latest version number for Viacrypt PGP is 2.7. Here is a brief summary of Viacrypt's currently-available products: 1. ViaCrypt PGP for MS-DOS. Prices start at $99.98 2. ViaCrypt PGP for UNIX. Includes executables for the following platforms: SunOS 4.1.x (SPARC) IBM RS/6000 AIX HP 9000 Series 700/800 UX SCO 386/486 UNIX SGI IRIX AViiON DG-UX(88/OPEN) Prices start at $149.98 Executables for the following additional platforms are available upon request for an additional $30.00 charge. BSD 386 Ultrix MIPS DECstation 4.x 3. ViaCrypt PGP for WinCIM/CSNav. A special package for users of CompuServe. Prices start at $119.98 Please contact ViaCrypt for quantity discount pricing. Orders may be placed by calling 800-536-2664 during the hours of 8:30am to 5:00pm MST, Monday - Friday. They accept VISA, MasterCard, AMEX and Discover credit cards.

These listings are subject to change without notice. If you find that PGP has been removed from any of these sites, please let me know so that I can update this list. Likewise, if you find PGP on a good site elsewhere (especially on any BBS that allows first time callers to access PGP for free), please let me know so that I can update this list. Because this list changes frequently, I have not attempted to keep it complete, but there should be enough pointers to let you easily find PGP. There are several ways to get the freeware PGP: ftp, WWW, BBS, CompuServe, email ftp server, and sneakernet (ask a friend for a copy). Just don't ask Philip Zimmermann directly for a copy. FTP SITES IN NORTH AMERICA There are some wierd hoops to jump through, thanks to the U. S. Department of State, at many of these sites. This is apparently because the U. S. Department of State wants to make it easier for people outside of North America to develop, distribute, use, or sell strong cryptographic software than people inside of the USA and Canada -- at least that is the effect of their rules. Telnet to net-dist.mit.edu, log in as getpgp, answer the questions, then ftp to net-dist.mit.edu and change to the hidden directory named in the telnet session to get your own copy. MIT-PGP is for U. S. and Canadian use only, but MIT is only distributing it within the USA (due to some archaic export control laws).

For a detailed rant, get ftp://ftp.csn.net/mpj/cryptusa.zip WHAT INTELLECTUAL PROPERTY RESTRICTIONS EXIST IN THE USA? MIT PGP is only for personal, noncommercial use because of restrictions on the licensing of both the RSA algorithm (attached to RSAREF) and the IDEA algorithm. PKP/RSADSI insist that we use RSAREF instead of the mpi library for reasons that make sense to them. For commercial use, use Viacrypt PGP, which is fully licensed to use both the RSA and IDEA algorithms in commercial and corporate environments (as well as personal use, of course). Another restriction is due to an exclusive marketing agreement between Philip Zimmermann and Viacrypt that applies to the USA and Canada only. Viacrypt has exclusive rights to market PGP commercialy in this area of the world. This means that if you want to market PGP commercially in competition with Viacrypt in the USA or Canada, you would have to create a new implementation of the functions of PGP containing none of Philip Zimmermann's copyrighted code. You are free to modify existing PGP code for your own use, as long as you don't sell it. Phil would also appreciate your checking with him before you distribute any modified versions of PGP as freeware. "PGP", "Pretty Good Privacy" and "Phil's Pretty Good Software" are trademarks owned by Philip Zimmermann. This means that if you modify an older version of PGP that was issued under the copyleft license and distribute it without Phil's permission, you have to call it something else. This avoids confusing all of us and protects Phil's good name. WHAT INTELLECTUAL PROPERTY RESTRICTIONS EXIST IN CANADA? MIT PGP is only for noncommercial use because of restrictions on the licensing of the IDEA algorithm. Because the RSA algorithm isn't patented in Canada, you are free to use the mpi library instead of RSAREF, if you want to, thus freeing yourself of the RSAREF license associated with the RSAREF copyright, which is valid in Canada. For commercial use, use Viacrypt PGP, which is fully licensed to use the IDEA algorithm in commercial and corporate environments. The exclusive marketing agreement with Viacrypt also applies in Canada. See the section on USA intellectual property restrictions for more details. WHAT INTELLECTUAL PROPERTY RESTRICTIONS EXIST OUTSIDE NORTH AMERICA? MIT PGP is only for noncommercial in areas where there is a patent on software implementations of the IDEA algorithm. Because the RSA algorithm isn't patented outside of the USA, you are free to use the mpi library instead of RSAREF, if you want to, thus freeing yourself of the RSAREF license restrictions. The RSAREF copyright holds outside of the USA, even though the RSA patent does not. The IDEA conventional block cipher is covered by US Patent 5,214,703 and European patent EP 0 482 154 B1. IDEA is a trademark of Ascom-Tech AG. Commercial users of IDEA (including commercial use of PGP) may obtain licensing details from Ph. Baumann, IDEA Lizenz Ascom Tech AG Postfach 151 CH-4502 Solothurn Switzerland Tel ++41 65 242828, Fax ++41 65 242847. WHAT IS COMMERCIAL USE? Use some common sense. If you are running a business and using PGP to protect credit card numbers sent to you electronically, then you are using PGP commercially. Your customers, however, need not buy the commercial version of PGP just to buy something from you, if that is the only commercial use they make of PGP (since they are spending, not making, money with PGP). If you are just encrypting love letters or other personal mail (for which you don't get paid) on your own personal computer, that is not commercial. If you are encrypting official business mail on your for-profit corporation's computer with PGP, that is commercial use. Note that there are some gray areas not covered above, and the patent owners of RSA and IDEA may differ from my interpretation in the areas not covered above, so if you are in doubt, you should consider the licensing of Viacrypt PGP (or outside of North America, direct licensing of IDEA) to be cheap legal insurance. Indeed, the license fee is probably a lot cheaper than a legal opinion from a lawyer qualified to make such a judgement. Note that I am not a lawyer and the above is not legal advise. Use it at your own risk. ARE MY KEYS COMPATIBLE WITH THE OTHER PGP VERSIONS? If your RSA key modulus length is less than or equal to 1024 bits (I don't recommend less, unless you have a really slow computer and little patience), and if your key was generated in the PKCS format, then it will work with any of the current PGP versions (MIT PGP 2.6, PGP 2.6ui, or Viacrypt PGP 2.7). If this is not the case, you really should generate a new key that qualifies. MIT PGP 2.6.2 should be able to use 2048 bit keys. Generation of 2048 bit keys was supposed to automatically be enabled in PGP 2.6.2 in December, 1994, but a bug caused the actual key limit to be 2047 bits.

For $20/year or so, you can have your key officially certified and published in a "clean" key database that is much less susceptible to denial-of-service attacks than the other key servers. People need not pay any fees to retrieve keys so published. Send mail to info-pgp(a)Four11.com for information, or look at http://www.Four11.com/ You can also mail your key to pgp-public-keys(a)c2.org, and it will be posted to the subscribers of that mailing list, sent to the keyservers, and posted to alt.security.keydist. To subscribe to the mailing list, send a message to majordomo(a)c2.org with "subscribe pgp-public-keys" in the body of the message. Another way is to upload it to the PGP public keys area of the Colorado Catacombs BBS (303-772-1062). Another way is to just send it to your correspondents. You could add it to your .plan file so that finger returns your key. You could add it to some of your postings. No matter which way you do it, you should have your key signed by someone who verifies that your key belongs to you, so that you don't have someone else generating a key that has your name on it, but that isn't yours.

Lance Rose writes anti-cryptoanarchy in WIRED
by rishab＠dxm.ernet.in 17 Dec '03

17 Dec '03

I've missed recent traffic so forgive me if this has already come up. Lance Rose writes a particularly twisted piece in the Idees Fortes section of WIRED 3.02 (February). His basic premise is that tradritional forms of copyright law are sufficient to ensure that the Net poses only limited problems to mass content producers such as Time Warner. I agree with this, as most people feel uncomfortable about 'stealing' however impossible it is to detect. Lance Rose, though, goes on to insist that the reason for the copyright law's strength will be the power of the omnipresent Net Cops (sic). So that you don't consider him entirely ignorant, he acknowledges the increasing use of anon remailers. However, he adds (repeatedly), "Can't we all use anonymous remailers to keep the Net knee-deep in infringing copies? Nope. Net cops can swiftly clean each new infringement out of the major online markets as soon as it appears." How will they do this so efficiently? By "deploying software agents" net-wide to "search out anonymous infringements." He later admits the possibility of "friend-to-friend" markets, but rejects the possibility of such markets growing out of hand, as "few or none of the participants will know everyone else in the circle" allowing cops to join them undetected (as if the Information Liberation Front would mind giving the _cops_ pirated software). "A symbolic legal attack" every once in a while will scare would-be black-marketeers. Later, he does discuss the hidden costs of acquiring pirated versus genuine stuff - "the time and effort needed to track down pirate dealers [...] who are so deep underground even the cops can't find them." Sheesh. And here we are, post-BlackNet, discussing untraceable paid-for anon-remailers (which exist today on Sameer's c2.org blind server) and data havens. I haven't bothered to hunt for Lance's address, which is not given, but really I thought someone as prominent a SysLawyer as him would be clued in. Nor have I found the time to send WIRED a letter. OTOH maybe ignorance, for LEA-friendly legislators who read WIRED, is bliss? Let the sleeping dog lie, etc, just finish your data haven code ;-] ----------------------------------------------------------------------------- Rishab Aiyer Ghosh "In between the breaths is rishab(a)dxm.ernet.in the space where we live" rishab(a)arbornet.org - Lawrence Durrell Voice/Fax/Data +91 11 6853410 Voicemail +91 11 3760335 H 34C Saket, New Delhi 110017, INDIA
