It's easy enough for remailers to, for example, pass out free tokens to other remailer operators.

To to it exactly would > require an infinite number of coins... The minimum denomination for each currency is (sort of) configurable. For instance, for Belgian Franks the minimum is 1 (and no '.'). If a bank requested a currency capable of handling a mimimum of 0.00005 we could make that happen real easy. Note that with the maximum coin size 2^15 times minimum amount, the maximum coin would get a lot smaller, so that it would become more impractical to pay large amounts in that currency. On the longer term we can of course even change - the 2^15 maximum - maximum number of coins per message (currently 75) if the requirements were there. // Marcel van der Peijl, DigiCash bv, http://www.digicash.com/~bigmac/ // ----------------- insert subliminal message here ------------------

NIST Draft Key Escrow Paper
by jya＠pipeline.com 17 Dec '03

17 Dec '03

[Forward] From: Elaine Frye <elaine.frye(a)nist.gov> Subject: draft key escrow paper May 20, 1996 Note To: Key Escrow Distribution List From: Ed Roback, NIST Subject: Release of DRAFT Key Escrow Paper FYI, today the Interagency Working Group (IWG) on Cryptography Policy released a DRAFT paper entitled "Enabling Privacy, Commerce, Security and Public Safety in the Global Information Infrastructure." The DRAFT paper discusses a voluntary draft key management infrastructure, supported by private sector key management organizations, that would permit users and manufacturers free choice of encryption algorithms, facilitate international interoperability, preserve law enforcement access, and, most importantly, provide strong system security and integrity. FYI, the paper was released by the IWG co-chairs Ed Appel (NSC) and Bruce McConnell (OMB). Comments on the draft paper are being solicited. No deadline is specified. At present, I do not have an electronic copy of the draft (25 pp). Copies are available through the OMB publications office at 202-395-7332. I anticipate that the document will soon be available widely on the net and will forward you a web address when available. ***************************************************** Elaine Frye Computer Security Division National Institute of Standards and Technology Bldg. 820, M.S.

MixMaster fair use
by Jim Choate 17 Dec '03

17 Dec '03

Hi all, Perhaps I am confused about what MixMaster's license allows. I have joined the confusing part (for me anyway)... README.no-export : All the files in this archive contain crpytographic code which is restricted by the ITAR regulations on munitions. These files may only be retrieved by US citizens, and only on condition of agreement not to export any of this software or dats, and to extract a similar agreement from any person they may transfer it to. To access the export-controled materials on this site, you must agree to "THE AGREEMENT" below. If your email address ends in one of the following: .edu .com .edu. .gov .mil .org .net .us .ca Do this by sending "THE AGREEMENT", exactly as it appears, to mix-request(a)jpunix.com If it does not, but you qualify to retrieve Mixmaster under "THE AGREEMENT", then send mail to perry(a)alpha.jpunix.com, explaining your situation. In either case you will be sent a message containing the name of a hidden directory in which you will find the controlled software. The name of the directory changes frequently, so you must get the name each time you want to access the hidden directory. -John A. Perry 5/6/95 -------------------------------------------------- THE AGREEMENT: I am a citizen or national of the United States, or of Canada, or have been lawfully admitted for permanent residence in the United States under the Immigration and Naturalization Act. I agree not to export Mixmaster, or RSAREF or any other software in this archive, in violation of the export control laws of the United States of America as implemented by the United States Department of State Office of Defense Trade Controls. Before I download Mixmaster, I will read and agree to the terms and conditions of the RSAREF license (in ftp://ftp.jpunix.com/pub/rsalicen.txt) I will use Mixmaster solely for non-commercial purposes. ---------------------------------------------------------- Directory name last changed at: Wed May 1 09:00:01 CDT 1996 End README.no-export What confuses me is the part above that states that I agree to use Mixmaster for solely non-commercial use. This is NOT GNU or copyleft. Jim Choate

I have a partial implementation of this for Mixmaster if anyone wants to try integrating it into the main code. It works (or worked) for single packet messages but I never finished the multi-packet code. Of course, if Mixmaster is being rewritten anyway then it won't be much use. AFAIR it also relies on the 'In-Reply-To:' field in the header working correctly. Mark

Yeah, but the attack model I was assuming was lawyers rather than intelligence agencies. The NSA could probably easily link the two together, but the Church of Foobar(tm) probably couldn't. They'd only have access to the logs on the ISP and the information you gave when you signed up, not the raw packets on the Net. Mark
