Another quick question. Frequently when discussing a cypher the question of whether it is a group arises. In the absence of further definition, is it safe to assume that the set of elements for this group is the cyphers with each possible key and that the operation for this group is composition? Paul

As an addendum to the bibliography that Tim Cole posted, there are three good papers in the July 1993 edition of _Physical Review A_ (vol. 48 no. 1): "Information-theoretic limits to quantum cryptography" by Stephen M. Barnett and Simon J.D. Phoenix, "Quantum cryptography without conjugate coding" by Simon J.D. Phoenix, and "Quantum computers and intractable (NP-complete) computing problems" by Vladimir Cerny. - Mark - -- Mark Chen chen(a)netcom.com 415/329-6913 finger for PGP public key D4 99 54 2A 98 B1 48 0C CF 95 A5 B0 6E E0 1E 1D

re: new rules: filing electronic tax returns
by Martin Minow 17 Dec '03

17 Dec '03

In an note to Cypherpunks, LaurenN(a)wri.org notes that the IRS will require fingerprints (and other information) for people filing tax returns electronically. My understanding is that this refers to professional tax preparers. Note that individuals are currently filing "electronically" by sending their return to an agency, such as the MacInTax people. The problem the IRS faced, as I understand it from a brief report on NPR, is that there was a lot of fraud going around -- people filing bogus returns with refunds, then disappearing with the money. LaurenN also wondered why CPA's and lawyers are exempt -- I would imagine that this is because their identity is known through their professional licensing. Just my speculation.

More quantum references.
by Doug Shapter 17 Dec '03

17 Dec '03

This appeared on sci.crypt.research, so many on the list may have already seen it. For those that haven't (thanks and credit to Tim Cole) : As one reply to the thread on Quantum Cryptography, I have put together this bibliography of what I could find on the subject about 1 year ago. If there are other references that are not included here, I, and I suspect other readers of this group, would be very interested in those references. Anyway, here is the list: 1. Blow, K.J., S.J.D. Phoenix, On a fundamental theorem of quantum cryptography, Jnl. of Modern Optics, Vol. 40, No. 1 (Jan. 93),pp 33-6. 2. Brassard, G., C.H. Bennett, Quantum Cryptography, Lecture Notes in Computer Science, Vol.325, 1988, pp. 79-90. 3. Bennett, C.H., G. Brassard and N.D. Mermin, Quantum Cryptography without Bell's Theorem, Physiacl Review Letters, Vol. 68, No. 5 (3 Feb. 92), pp. 557-9. 4. Bennett, C.H., Quantum Cryptography Using Any To Nonorthogonal States, Physical Reveiew Letters, Vol. 68, No. 21 (25 May 92), pp. 3121-4. 5. Bennett, C.H., Quantum Cryptography: Uncertainty in the Service of Privacy, Science, Vol. 257, (7 August 92), pp. 752-3. 6. Ekert, A.K., J.G. Rarity, P.R. Tapster and G. M. Palma, Practical Quantum Cryptography Based on Two-Photon Interferometry,Physical Review Letters, Vol. 69, No. 9 (31 August 92), pp. 1293-5. 7. Werner, M.J. and G. J. Milburn, Eavesdropping using quantum nondemolition measurements, Physical Review A, Vol. 47, No. 1 (January 1993), pp. 639-41. 8. Stewart, I., Schrodingers Catflap, Nature, Vol. 353, (3 October 1991), pp. 384-5. 9. Bennett, C.H., G. Brassard and A. K. Ekert, Quantum Cryptography, Scientific American, October 1992, pp. 50-57. 10. Ekert, A.K.,Quantum Cryptography based on Bell's Theorem, Physical Review Letters, Vol. 67, No. 6 (5 August 91), pp. 661-3. 11. Bennett, C.H., F. Bessette, G. Brassard, L. Savalle and J. Smolin, Experimental Quantum Cryptography, Proceedings of Eurocrypt '90, also in Journal of Cryptology, Vol. 5, No. 1 (1992), pp. 3-28. 12. Bennett, C.H., G. Brassard, C. Crepeau and M-H. Skubiszewska, Practical Quantum Oblivious Transfer, Proceedings of Crypto '91. 13. Bennett, C.H., and G. Brassard, The Dawn of a new era for quantum cryptography: The experimental prototype is working !, SIGACT News, Vol. 20, No. 4 (Fall 1989), pp. 78-82. I hope this is a help to those of you just getting started. Many of the articles have their own bibliographies, but htese were the articles that I could find in my files. Again, I hope this helps.

>From Sandy Sandfort: Acapulco H.E.A.T., with dubious crypto and suspect technology, has become an inside joke for Cypherpunks. When we watch it, we see things the average person misses. This is something we share, and something that helps create the lighter side of Cypherpunk culture. ...................................................... Yeah, Rishab.

-----BEGIN PGP SIGNED MESSAGE----- FORTRESS remailers should be disguised in some way: "DBN announced solemnly that it was everyone's duty to turn in all computers and radios to the authorities for the duration of the Emergency. Not many were impressed by this pronouncement unless you counted laughter. I'd hate to be on the side trying to confiscate everything. That cactus might be a combination photovoltaic cell and radio antenna with green chlorophyll-enriched paint. Or it might just be a cactus. Maybe that flag pole is a hidden shortwave antenna. Should we tear down our own flag? That car engine, vacuum cleaner, hospital centrifuge, or those countless damned white-noise decoys might be unauthorized spread-spectrum radio transmitters. Or not. The bitter end had come, but the Feds wouldnÕt back down..." Another Little Brother problem: "Consumers wanted businesses to 'get it' concerning their preferences, without any effort on their part. But they insisted on absolute individual privacy. A method of scanning the face was devised that could evaluate and report the emotional state of the viewers, without disclosing the identity of any particular viewer, via a blind-audit protocol. This compromise was accepted by most broadcast receiver customers. It was not generally known that the biggest consumer of collective emotional data was the Department of National Security. The data was purchased under a number of marketing research company names, then transmitted directly to DNS in real time, making it the most important tool DNS had for "the manufacturing of consent." A Presidential speech was broadcast, and the sum of the viewer reactions was received. The speech program was adaptive, so statements evoking the most positive response were generated, if they fell within the policy constraints set by the Directorate of the Department."

It's easier to make an omlette out of eggs than to make eggs out of an omlette so encryption should remain well ahead of decryption. This differs from the popular view that decryption would eventually win the "war" with the encryption and devise a way of defeating *any* possible code/cipher. This "fact" was expressed in Edgar Rice Burroughs' Mars stories where he said that the Martians didn't use codes much because they were vulnerable. See also Sneakers in which we have a "black box" decyption device that can break any code. Also the guy who confronted me at the London conference last year and said "they broke the satellite movie coding system so why can't they break PGP?" I wonder where this idea comes from. DCF "Who was shocked, shocked by the end title sequence in Sneakers which features a newsreader describing how good commie liberals like the Robert Redford and Dan Ackroyd characters are using their decoding device to steal money from the Republican National Committee and transfer it to Greenpeace and all the usual suspects. Looks like those guys don't believe in democracy. That sort of thing is worse than the Watergate break in."
