MATH: Brands' cash, Hal's post #2

Paul will choose x = 351 to be his secret key, so GX = 10^351 mod 17389 = 16987 is his public key.

Hi, I built crypt awhile back. I'm pretty sure I got the source from ghost.dsi.unimi.it. Now that site says everything has been moved to ftp.dsi.unimi.it, but there seems to be no crypt.c there, although there is plenty of other crypt stuff. In the meantime, I was cleaning up (big mistake), and lost my copy of the source. Can someone tell me where the source is for the crypt program?

Data Haven via FTP
by dfloyd＠runner.utsa.edu 17 Dec '03

17 Dec '03

-----BEGIN PGP SIGNED MESSAGE----- Here is a possible way to set up a data haven using FTP, instad of mailing your stuff. Term is a program that allow you to set up pseudo-SLIP between two boxes. It also allows one to redirect ports. If it would be possible to redirect say port 10000 on box A to the ftp port of box B, then one could FTP to box A and that would be for all intents and purposes an "anon remailer" for box B. This could be chained as well... port A on Box A to port B on box B to port C on box C to ftp on the target box. This is a very rough idea. Authication is still a problem. Possibly have the files in a directory that is readable, writable, but not "ls"-able, and the files PGP encrypted, or put them in incoming, and the server encrypts them with the owner's PGP key, and renames the file. - -- Just some rough ideas from one that is awake much too late.

Media Bias

(Fairness and Accuracy in Reporting - a New Left anti-media-bias watchdog inspired by the right-wing Accuracy In Media group), and have heard him on KPFK. I saw the movie about him and have read some of his writing, including articles in Anarchy magazine. The movie, as I remember it from a year or two ago, claims that the East Timor people suffered the same magnitude of oppression at the hands of the U.S.-supported Indonesians, as did the Cambodians under the Khmer (were they Soviet or Chinese puppets? Or independent?). In a dramatic scene in the Chomsky film, the press reports about the Cambodian killing fields, convenient for the U.S. anti-Communist fascist imperialist running-dog empire, *ahem*, rolled across the floor of a warehouse, with lights flicking on as the spool of printouts passed under them, covering a great length of the floor. The reports of East Timor atrocities were relatively non-existent. How do you explain that, Man?! Fight the Power! Right Awn! I don't say that Chomsky isn't biased himself, or that Timor equals Cambodia, I'm just telling you what I remember. >Your claim, and Chomsky's claim, is a flagrant lie >... the Ambassador and the editors of the New York times ... >could not have clocked up as many as Amin did in real life, >let alone in Amin's "wildest fantasies".

When I saw him live and on stage, Chomsky said he thought the genocide stories about Cambodia were as bogus as the other 99% lies told by the lapdog "adversarial" press (like Yellow Rain "chemical warfare" actually caused by bee droppings). Or the Gulf of Tonkin incident. Or Terrorists, Pedophiles, Money-Launderers, and Dope Dealers that will surely get us all if Digital Telephony and Clipper aren't adopted. Can we really blame him for doubting the unreliable media? He stopped defending Khmer Rouge (sp?) when he became convinced that the killing fields were real. In other words, he would never support genocide. That's the Party Line anyway, comrade. >But Chomsky defines peoples free choice to say one thing rather >than another thing, to listen to one source rather than another >source, to be "extreme coercion and control". What is the source of this accusation? Chomsky is an extreme free-speech anarchist, from what I've read about and by him. He even defended the right of Holocaust-revisionist Robert Faurisson to speak about his historical beliefs against the French state's claim that it has the right to determine what is "historical fact." Chomsky himself does not deny the Holocaust. >...when Chomsky argues that speech is coercion, and choice is submission, >I know that he and his pals in the government are planning to enhance our >civil liberties by protecting us from that speech, and to enhance our >lives by rescuing us from that submission. Fine. Death to P.C. government-imposed "sensitivity." But, what does Chomsky have to do with this? According to the S.F. Weekly in 1989, Noam Chomsky was once described in a college newspaper as both "a Nazi sympathiser" and "a Soviet apologist." That's a neat trick, maybe possible during the Hitler-Stalin pact. However, the Soviets wouldn't let him enter the worker's paradise because he called it "The Dungeon State" in one of his many books. And his support for free speech, even for those with controversial non-P.C. positions, makes his Nazi qualifications, and your "speech is coercion" accusation, suspect.

IBM-Led Consortium. Any thoughts?
by nobody＠cass156.ucsd.edu 17 Dec '03

This just in. I haven't seen it posted so I thought I would. ===========================begin forwarded message========================= IBM-Led Consortium Signs Federal Contract to Develop NII Protocol Sept. 16 CONTRACTS/VENTURES HPCwire ============================================================================= A news release from IBM Corporation -- Somers, N.Y. -- A consortium of organizations led by IBM has been awarded a contract by the U.S. government to develop open industry software protocols that will integrate computing environments across the U.S. manufacturing base. The protocols, based on object-oriented technology using Distributed System Object Model (DSOM) and System Object Model (SOM), will make it easy for organizations of any size to share the same information so they can work more cooperatively and efficiently on projects together. The Cooperative Agreement that was just signed with the U.S. Department of Defense (DoD) calls for the development of National Industrial Information Infrastructure Protocols (NIIIP) as part of the Technology Reinvestment Project (TRP). NIIIP will allow disparate systems of different manufacturers to be linked and exchange information real-time so companies can work as a single, integrated "virtual enterprise" to address a business opportunity. Much of the NIIIP work will be consolidating and "harmonizing" the many sets of existing protocols, and then doing pilot projects and demonstration work to prove the efficacy of the recommended approach. The NIIIP protocols are viewed by the DoD's Advanced Research Projects Agency (ARPA) as one of the fundamental building blocks of the National Information Infrastructure (NII). Since all U.S. manufacturing companies will be able to use the NIIIP protocols, the government expects that American industry's competitiveness will increase with their use. The TRP is designed to link the best of America's defense and commercial industries. TRP projects are intended to create "dual use" technologies that have both military and commercial applications. They help defense firms make the transition to commercial markets, prepare defense engineers and workers for the manufacturing industries of the future, and help prepare commercial firms to provide defense products in case of national emergencies. The $60 million project is made up of federal matching funds and existing and incremental development costs, as well as in-kind funds from the consortium members. The consortium members will invest more than half of the total project costs. In addition to IBM, the other members of the consortium are: STEP Tools, Inc.; Enterprise Integration Technologies; UES, Inc.; the University of Florida; Texas Instruments Incorporated; Rensselaer Polytechnic Institute; Digital Equipment Corporation; Lockheed Aeronautical Systems Company; MESC Electronic Systems, Inc.; International TechneGroup Incorporated; Taligent; CAD Framework Initiative, Inc.; General Dynamics, Electric Boat Division and the National Institute of Standards and Technology. The NIIIP proposal was sponsored by the IBM Manufacturing Industry and also includes participation by the IBM Microelectronics Division, Software Solutions Division, and the Networking Software Division. Their products include a broad array of software, hardware, and integration services to provide concurrent engineering and computer-integrated manufacturing (CIM) that help manufacturers reduce time to market, improve product quality and lower unit costs, while meeting environmental and other international standards. As overall Program Manager, IBM will manage the system design, development, and integration, as well as the establishment of commercial channels for delivery of the project's resultant software products, planned for completion in 1998. IBM also will be responsible for skills transfer through its CIM in Higher Education Alliance, a nationwide IBM-sponsored organization consisting of 97 U.S. colleges, universities and technical institutions. Selection of the IBM-led consortium's proposal from among the 2,850 proposals submitted is a significant endorsement of IBM's leadership in the field of information technology with proven experience in creating open software products, providing technical software support, and managing a broad array of distribution channels. The DoD announced earlier this year that it had selected this consortium to develop NIIIP under the TRP, but it held off formally approving the deal until the Cooperative Agreement was reached. ***************************************************************************** H P C w i r e S P O N S O R S Product specifications and company information in this section are available to both subscribers and non-subscribers. *900) Ampex 915) Genias Software 916) MasPar Computer 912) Avalon Computer *930) HNSX Supercomputers 905) Maximum Strategy 921) Cray Research Inc. 902) IBM Corp. 906) nCUBE 907) Digital Equipment 904) Intel SSD *932) Portland Group 909) Fujitsu America 928) Kendall Square Res 935) Silicon Graphics *Updated information within last 30 days ***************************************************************************** Copyright 1994 HPCwire.

Crypto irrelevant to hit men
by rishab＠dxm.ernet.in 17 Dec '03

17 Dec '03

Crypto and anon escrow are largely irrelevant to the world market in assasinations, nuclear terrorism or whatever. To put my response to the whole 'HIT MEN' thread very concisely: 1. 'crypto anarchy' does make it easier for people to _hire_ murderers. It does NOT make it any easier to _commit_ murders. 2. it may be difficult for an escrow agency to have good reputations among murderers as well as doctors. I agree with Sandy that people don't bother only about reputations for specific activities, but consider organizations as a whole. However, reputations as I defined them in my "Social punishment" posts are clearly valid within possibly independent social units. You may have a good reputation with murderers but not with Aunt Maud. 3. Sandy says (2) leads to agencies with limited clientele, therefore higher rates, therefore more fraud. Narcotic drug trafficking is a $500 BILLION annual industry (HDR 1994). Part of the high cost is the 'illegal' and possibly 'immoral' status of the trade. This does not necessarily mean an unsustainable market - indeed it's one of the world's fastest growing businesses. Nor do the high premia result in unsustainable levels of fraud. I wouldn't put my money in a bank run by the Cali cartel, no matter how unlikely they are to ever fail. But enough people in the drug business trust them. Enough people trust the shady runner in the New York alley. 4. A agency only need to have a good reputation with its _clients._ It doesn't matter that others hold the agency in poor regard. Conversely, the agency _needs_ a good reputation with its clients, it doesn't matter that others hold it in _high_ regard. To conclude, I don't believe that crypto anarchy will significantly change the _amount_ of murders and such crimes. Or even the ability of the law enforcement to solve them (even without crypto, hardly any murders are solved by tapping phones). Crypto anarchy will only make it possible to be involved in such activity from anywhere in the world, just as cyberspace will enable lots of others to interact more conveniently. ----------------------------------------------------------------------------- Rishab Aiyer Ghosh "Clean the air! clean the sky! wash the wind! rishab(a)dxm.ernet.in take stone from stone and wash them..."

Fast Modular Factorial?
by mpd＠netcom.com 17 Dec '03

17 Dec '03

A small question about large integer math... We are all familar with the fact that x^(2^n) mod p may be evaluated with only n modmults which accumulate geometrically increasing powers of x. Does a similar fast algorithm exist for computing (2^n)! mod p? The only difference here is that one is accumulating a huge product of consecutive integers instead of the same integer multiplied many times. I am interested in values of n around several hundred. I have played with this quite a bit and am unable to see any easy exploitable symmetry which would lead to an efficient algorithm. Any ideas? -- Mike Duvos $ PGP 2.6 Public Key available $ mpd(a)netcom.com $ via Finger. $

PHOTO>Electronic Imaging vol. 37 no. 6, 1994 had a couple of very comprehensive articles on copyright protection trends. The list of available products included: * Stego (Mac shareware) which can embed data in and retrieve data from PICT images w/o changing the appearance or size. They plan to add other image formats as well as audio and video for both Mac & PeeCee platforms. * Nikon is developing a method of incorporating an electronic signature into their digital cameras. This signature would include lens settings, exposure, time/date, plus the photographer's personal digital signature. They want it to be compatible with AOCE (below). * AOCE (Apple Open Collaboration Environment technology) is integrated into Mac System 7 Pro as Digital Signature Manager and, guess what, it uses RSA licensed public-key encryption. * Kodak and RSA are working on an encryption scheme for photo CDs where only the low-res images are freely viewable, the hi-res ones require a key to access. * Common Ground (Mac & PeeCee) saves text and images as a Portable Document Format(PDF) and has security built-in that can restrict the text/graphics from being copied or printed. * Kodak Pro Photo CD allows copyright information and color settings to be tagged onto any image. This information can latter be read by Kodak Photo CD Access Plus or Photo CD programmer's toolkit. * (icky toggle methods not transcribed) For futher reading they suggest, "Protecting Intellectual Property Rights on the Information Superhighways" by Joseph L. Ebersole. The paper includes discussion of laws, copyright management, encryption, standards, and glyphs-to-video steganography.

Re: Fast Modular Factorial?

I find that for the numbers I have tried, that (p-1)! mod p = (p-1) if p is prime, else it equals 0, with one exception (p=4). So if this is true (probably a standard result; it sounds familiar) then it might actually be easier to find the factorial of a larger number mod a prime than a smaller one. Hal

CPs write Bumper Stickers
by merriman＠metronet.com 17 Dec '03

17 Dec '03

Got my samples of bumper sticker stock from Williams & Macias today, and it looks *real* good. Nice, heavy paper, feels like some kind of plastic coating on it to make it weather-resistant. The description sheet that came with it says that it can also be run through copiers and offset presses, that it can be drawn on directly, and takes color (dry-toner). W&M is calling them SlapSticks. The 2041 (3 stickers/sheet) has 3 short (but full-width) areas; the 2042 has 2 full-height areas. The stuff also comes with two different adhesives: "temporary" and "removable". The "temporary" is to allow washing off with soap and water; the "removable" is more durable. From the descriptions, it sounds like the difference between a post-it note, and adhesive tape (roughly). Each sticker is on it's own little die-cut area, and the areas are separated with perfs to make separation easier. Prices are $19.95 for 20 sheets, with Bumper Sticker Remover fluid for the "removeable" stickers at $2.75 for 11 oz. can. 2x41 is 3 stickers/sheet, 2x42 is 2 stickers/sheet. Replace x with 0 for removable adhesive, use 1 for "temporary". The number (again) is 1-800-310-0890; Williams & Macias 3707 South Godfrey Blvd. Spokane, WA 99204-5753 (509) 624-5170 Only got sampled one sheet of each kind, though :-( Dave Merriman - - - - - - - - - - - - - - - - - - - - - - - - - - Finger merriman(a)metronet.com for PGP/RIPEM public keys and fingerprints.

Any non-prime containing > more prime factors than n! doesn't satisfy this test; nor does any > non-prime containing factors > n. > Will think on this. It seems to me that if you have a even number of prime factors you can multiply them out and get an even number which you should be able to remove easily. Do you mean that the number of prime factors is greater than n! or greater than the number of prime factors of n!? Also, consider that in the case of a x>>n you might actually run out of enough factors smaller than n to remove. This is one case I didn't have time to look at earlier. Right now I am looking at behaviour where x>(n)^1/2 and also when x>(n!)^1/2. > 6! == 2 * 3 * (2*2) * 5 * (2*3) == 720 > 116 == 2 * 2 * 29 > 27 == 3 * 3 * 3 > > 720 mod 116 == 24 > 720 mod 27 == 18 > > 6!= 2 * 3 * 4 * 5 * 6 = 720 116 is > 6 so this does not disprove my assertion. The factor which is left over, ie 29, is prime. 27 is > 6 so this does not seem to disprove it either since in 6! there is a 3 * 3 which removes one of the factors and you are left with 3 which is prime. Consider x=n again, this means that n! is really n(n-1)! and the mod of (n!)modx is equivalent to n(n-1)!modx which leave us with a multiplicitive factor of (n-1)! and a remainder of 0. One other point that may be irrelevant is that n! is always an even number. The reason is that the very last multiplier is 2.

As a footnote to my previous message, (p - 1)! ~ -1 mod p whenever p is prime (Wilson's theorem). This follows immediately from the general rule that I gave. - 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
