REMAIL: timestamp

Well, I decided to comment out the timestamping (what a short lived feature! :-) I'm starting to work on a caching remailer, and the timestamping info could be used to map input and output mailing pairs - especially since I was going to change the stamps to read "X-Time-In:" and "X-Time-Out:". That would defeat the entire purpose of caching... <klbarrus(a)owlnet.rice.edu>

REMAIL: timestamp
by nobody＠Menudo.UH.EDU 07 Sep '93

07 Sep '93

-----BEGIN PGP SIGNED MESSAGE----- With all the talk of timestamps, I decided to implement a simple timestamp on the remailer at elee9sf(a)menudo.uh.edu. It is by no means a cryptographically secure timestamp. The remailer adds a timestamp header field to outgoing messages. It looks like this: X-Timestamp: hour:min:sec on day:month:year For instance, this message should have one. This nice thing about this is that in the process of stripping mail headers, the remailers will automatically filter the X-Timestamp as well. Thus, if a message is chained through several remailers, only the last remailer's timestamp (if any) will appear in the final message. klbarrus(a)owlnet.rice.edu -----BEGIN PGP SIGNATURE----- Version: 2.3a iQCVAgUBLIzEmIOA7OpLWtYzAQFTFwP9F84EDoIh8XmRDuY4463N5U9jAtLeXBnz WtrGuLF10Vngz3GDkGn4BQF4GQfEUgbYFcosZs3bV8/t0SP487PpnvblV7HG3/rO Fs39piJYTVETnBl14Gt8xVic8GxPvKuAatqk+J9rvKpj1eTklxFT2a/bqOCCJ1FK TuhZQHAVR5U= =U47Z -----END PGP SIGNATURE-----

Munitions class encryption
by Forrest Aldrich 07 Sep '93

07 Sep '93

I am curious about what constitutes "Munitions" class cryptography; is there really anything out there available to "us" that is of this "quality" (being unsure of where pgp stands with this). If there were, would it be feasible to have something like this that is software-only-based? If so, and it originated outside of the USA, I wonder what the officials would think of its use. On that line, I wonder if traffic-analysis isn't being performed right now to determine where the heaviest use of PGP exists. Perhaps to some, the idea of traffic-analysis (on the internet, that is) might sound a bit silly; however, I have been assured that this type of activity is none-the-less a regular one, and is used for many purposes. Anyone have more details? I had a friend who worked in the COMM center at a former air force base. He had a top secret clearance, and said that one of his duties was to separate (and deliver?) classified printouts. He said that the stuff he read in there would 'blow your mind'. He said that (this was only a few years ago) the government used encryption cards (computer cards) which were changed on a daily basis. Which makes me wonder if "Munitions" class cryptography would indeed require hardware support.

I have two pet issues: 1. Who Owns Cryptography? David Kahn's "The Codebreakers" shows that strong cryptography (as strong as that used by the military of the time) has almost always been invented by and used by private individuals, throughout history. The US Gov't (especially the NSA) has been trying to give the impression that it owns cryptography. The case needs to be made that cryptography inventions occur spontaneously in the minds of individuals and that cryptography is used to guard privacy (of both files and conversations) in a way the government: a. could not control if it tried, short of "1984" style room bugging, informants, ... b. should not control because of the 4000 year history of private ownership of cryptography. 2. Export Laws for Cryptography -- There are three classes of cryptography, logically: i. Munitions ii. Commercial iii. Public Domain Munitions cryptography would include systems using government classified algorithms or incorporated in physical hardware which has been hardened for battlefield use. Commercial would include systems which are proprietary to some company and sold by that company. Public domain would include systems which have been fully published (DES, RSA, DH, IDEA, <many older systems>, ...), have been implemented from those publications and which are effectively already in the hands of any interested high school kid. These are often available on public BBSs, worldwide. (PGP, for example) It makes sense to control munitions via ITAR and commercial systems via the commerce department, while leaving public domain systems uncontrolled c/o freedom of speech. What can be done to make these points? If these are not law review issues, what can I do as a private citizen to put these forth? - Carl

Re: Remailer Reliability

If you want reliability, you can take a page from the fault tolerance business. Replicate the remailers. (There are many papers on this topic. See, for example, ISIS from Cornell and Manetho from Rice.) Example: I send to r1 and r2. Each of r1 and r2 sends to r3 and r4. r3 and r4 each take the first message to arrive and drop the second. at the end of the chain, you have rm and rn. rm and rn each get the message (drop the second) and then decide between them who gets to post it. The one who gets to, does and tells the other that it's all done -- at which time the other drops its copy. Death detection is by time-out (but only rn and rm need to delay operation until the time-out -- to prevent multiple postings from a split-brain network.) Expensive (4x the message traffic) -- but fault tolerant. - Carl
