Sounds like a market niche to me...people at the border could sell the plate numbers (and even full DMV searches) of cars they see....maybe with a higher price paid for "real-time quotes," and a lower price paid for "15-minute-delayed quotes." Just like the stock market. By the way, I'm watching MSNBC and they're engaging in a fretfest about this Oregon situation, with calls for "regulating the Internet." "There is no good reason for this to be on the Internet." is one line I heard. (If the stuff is legal to own, and is "public information," just what exception to the First Amendment could be used to bar publishing?) BTW, this latest issue is similar to the flap several years ago over Lotus' plan to sell to the public a CD-ROM of zipcodes and whatnot. (I think it was called "Lotus Neighborhoods.") So-called "privacy activists" raised a hue and cry and the plan was cancelled. Of course, corporations and other such interest groups can get the data, so not much was accomplished. Many of us thought it was a blow to real privacy issues. The Ostrich Security Principle: "It is more important to have the _illusion_ of privacy than to have real privacy." --Tim May Boycott "Big Brother Inside" software!

secret sharing protocol - new or reinvented ?
by peter.allan＠aeat.co.uk 17 Dec '03

17 Dec '03

Schneier in That Book 2nd Ed p73 refers to "secret sharing with disenrollment", but without giving details of such a scheme. He gives a reference [1004] I think, by K Martin, which has about 10 pages on the subject. But I have not got it. I planned a "secret sharing with disenrollment" scheme last night. Here is a brief description and if somebody with the book tells me it's new (unlikely I think) I'll write it up in more formally. It has a resemblance to S/Key, but in the other direction and using a keyed hash function. If you see snags with this, I'd like to know. Peter Allan peter.allan(a)aeat.co.uk Trent chooses his shareholders, a block cypher (or keyed hash), a threshold, and a number of steps. The threshold should be more than half the number of shareholders. (Say 15 shareholders for a 10 out of 15 scheme, using DES, over 20 steps.) Trent generates 15 64-bit DES keys (not caring about parity), and gives them securely one to each shareholder. He introduces all shareholders to each other so they can recognise each other later. He also tells them the number of steps (here 20). Trent (in possession of all shares) calculates the secret, which is a 64-bit number. Obviously this could just be a key for a secret not yet created at share distribution time. Secret calculation is performed by executing the required number of steps, and the result of the last step is the secret. Disenrollment (conducted by shareholders, presumably under orders from Trent) is the performance of one step, omitting those to be disenrolled. (The number of possible disenrollments is limited by the threshold.) One step is this set of actions: Using a normal threshold scheme, such as Shamir's Lagrange Polynomials a sufficient number of shareholders construct a single secret from their shares. Call this M. M is then used to update all their shares using a keyed hash function. Table 18.1 suggests H_i = E H_i-1 (M) XOR M M and every H_i-1 is destroyed. Now those absent from the meeting have no M value to advance their share, and nobody (even the other shareholders following a change of heart) can reproduce it for them. Shareholders deduct 1 from the number of steps still to be performed.

What's the story with the tiger.team(a)tigerteam.org bounces? I've been getting quite a few of these from time to time, once when sending a message Sterndark.

Re: e$: Watching the MacRubble Bounce

Actually, DEC is trying to stay in business building expensive Windows boxes. The numbers I remember hearing are something like: 1,000,000 Unix machines 10,000,000 Macs 150,000,000 "PCs" (presumable not running *nix) Why should we care what platform people develop for? I use all of 'em. If a package supports more than one, all the better. As to why one should develop crypto stuff for unix, the demographics of this list are probably reason enough.. I use PCs as my main platform, but I get the distinct impression that most of the folks here use unix primarily.

Box 1684, Lake Worth, FL 33460. $12 for subscriptions and $1 for a sample copy. Dan Tenenbaum (dante(a)microsoft.com or dante(a)halcyon.com) CBS Liable for Filming Search In a landmark decision a federal court in New York has ruled that a CBS film crew and Secret Service agents are liable for filming and broadcasting a search of a private citizen's home. It is the first reported court decision to hold a television broadcaster liable for accompanying police agents on a search and filming it for the broadcast. Anyone who has watched "Cops," "Hard Copy," "America's Most Wanted," or any of the "real life" cop shows has seen the degrading and propagandistic manner in which the victims of police repression are portrayed. The broadcasters and the police can be sued and held liable for such actions. In 1992 Secret Service agents obtained a search warrant from a federal court authorizing the search of an apartment shared by Babatunde Ayeni, his wife Tawa, and small son Kayode, seeking evidence of a credit card fraud operation. At 6PM on March 5, 1992, several Secret Service (SS) agents forced their way into the Ayeni residence announcing they had a warrant to conduct a search and ask questions. Only Mrs. Ayeni and her son were home at the time. At about 8:15 four more SS agents arrived with a film crew from the CBS news program "Street Stories." The CBS film crew was never identified as CBS employees. The CBS crew followed the SS agents and taped them as they searched the apartment. They took closeup shots of the home's interior, its closets, personal letters, family photos, etc. In the apartment's foyer an SS agent was interviewed about the modus operandi of people who commit credit card frauds and the tools of their trade. During this tape sequence the SS agent implied the complicity of the other residents of the Ayeni apartment. No evidence implicating the Ayenis in any illegal activity was found during the search. One of the agents was filmed expressing his disappointment. The Ayenis filed suit against the federal agents as well as CBS, contending that the search and its filming violated their fourth amendment right to be free from unreasonable search and seizure. In his opinion Judge Weinstein agreed with the Ayenis. The defendants sought qualified immunity, which the court denied. Under the doctrine of qualified immunity government agents are entitled to be free from liability for money damages even if they violate constitutional rights as long as the right is not "well established" so that a person of reasonable intelligence would know that the right violated was recognized. In the case the court held that any reasonable police agent would have known that it is unconstitutional to have private citizens accompany them on a search to film and broadcast the search. The court relied on 18 U.S.C. sec. 3105 which requires that search warrants be served by an official authorized to serve the warrant and by no other person unless their assistance is required in conducting the search, i.e. an accountant, forensic expert, etc., depending on the nature of the offense being investigated. Thus, the SS agents should have known that having a film crew taping their activities was illegal. Courts have previously held that taking photos is a "seizure" within the meaning of the fourth amendment. CBS also claimed qualified immunity from suit. The court notes that private entities are not entitled to qualified immunity from suit, it only applies to government actors. The court used harsh language in condemning the actions by the SS and CBS. "The search warrant was issued to agent Mottola and other agents of the Unites States Secret Service for precise and limited purposes. It authorized their entry into the Ayenis' home only to search for items related to credit card fraud. Agent Mottola's act of facilitating the CBS camera crew's entry into the apartment and its filming of the search exceeded the scope of the warrant. It was allegedly in clear violation then well [sic] established fourth amendment principles. ...it is the equivalent of a rogue policeman using his official position to break into a home in order to steal objects for his own profit or that of another." For immunity purposes it would be "...grossly unreasonable for a government agent not to have known that the presence of private persons he invited in so that they could titillate and entertain others was beyond the scope of what was lawfully authorized by the warrant. "CBS had no greater right than that of a thief to be in the home, to 'capture' the scene of the search on film and to remove the photographic record. The images, though created by the camera, are a part of the household; they could not be removed without permission or official right....The television tape was a seizure of private property, information, for non-governmental purposes." It is entirely possible that litigation by the victims of this type of police and media activity may be able to halt the spread of "police TV." Findings of liability against both police and the broadcaster will see to it that police activity is not broadcast to "entertain and titillate." So if you've been filmed against your will during a police search you too can sue for an invasion of your privacy and your fourth amendment rights. The court decision is reported at: Ayeni v. CBS, Inc., 848 F. Supp 362 (ED NY 1994). rgds-- TA (tallard(a)frb.gov) I don't speak for the Federal Reserve Board, it doesn't speak for me. pgp fingerprint: 10 49 F5 24 F1 D9 A7 D6 DE 14 25 C8 C0 E2 57 9D
