Full details: http://www.shef.ac.uk/~sfl/meetings/itconf.html PLEASE DISTRIBUTE AND LINK TO YOUR WEB-SITE: Scientists for Labour - IT & Communications Group Conference on Information Superhighway Policy --------------------------------------------------------------------- "Liberty on the Line : Opportunities and Dangers of the Superhighway" --------------------------------------------------------------------- Chaired by Geoff Hoon MP, Shadow Minister for IT Thursday 14th November 1996, 9am - 5:30pm MSF Centre, 33-37 Moreland Street, London EC1 (Angel tube) --------------------------------------------------------------------- For further details or to reserve a place contact: Caspar Bowden, SfL IT & Comms co-ordinator (qualia(a)dircon.co.uk) The debate over Internet regulation in the UK has focused mainly on censorship, but the standards for control of "encryption keys", currently being formulated nationally and internationally, will lay the permanent foundations on which the Information Society is built. The long-term implications for civil liberties have received little public attention outside the Internet community. Scientists for Labour is hosting a conference to look at the data protection and economic issues arising from the integration of digital signatures, electronic copyright management, and digital cash. What kind of regulatory apparatus will allow rapid growth of an information economy, but prevent misuse of personal data ? *) New government proposals on "Trusted Third Parties", which aim to preserve law enforcement and national security capabilities for warranted interception of communications (to fight crime and terrorism), place only procedural not technical limits on the scope of Superhighway surveillance. *) Super-computers have the potential to conduct random electronic "fishing expeditions" against the whole population. Telephone and letter interception cannot be automated : digital monitoring can. Will legal safeguards against abuse offer adequate protection in perpetuity, or can cryptographic protocols be designed which make Superhighway mass- surveillance impossible, while still allowing criminals to be targeted ? Computer and legal policy experts will explain the principles of the different technologies, and the international and commercial context, in a search for interdisciplinary solutions.

10-27-96. WaPo: "Heightened Tensions Over Digital Taps. Telecommunications Industry, FBI at Odds Over High-Tech Tools" Telco officials say that the FBI aims to force phone companies to build extensive surveillance systems into their telephone networks that will likely open new avenues of surveillance for government wiretappers. Freeh has testified that his agency is "simply trying to catch up with technology." In recent interviews, however, his senior aides insisted there are virtually no limits to the types and amount of information they can intercept once a judge signs a court order. "It would be stupid of us, as a police agency, not to take advantage of information in the system to solve crime," said James Kallstrom. "That shouldn't shock you. The technology offers a lot more." ----- http://jya.com/bye4th.txt (10 kb) ftp://jya.com/pub/incoming/bye4th.txt BYE_4th

some RSA questions
by Jüri Kaljundi 17 Dec '03

17 Dec '03

Some questions about writing a program that uses RSA. Let's assume we have 3 participants (Alice, Bob, Carol). The idea is for Bob to send an encrypted and signed message to Alice. Although Bob constructs the message, signs it and encrypts it, it is Carol who can decide some parts of the message. The message is small, 200-400 bytes in length. Some of the contents of the message are always the same (field names) and the message looks much like mail headers: Field1Name: field1contents Field2Name: field2contents Field3Name: field3contents Carol can decide, what goes into the field contents. Now the easiest way would be to sign the message using Bob's private key and encrypt is using Alice's public key. What Carol wants to do is forge similar messages without help from Bob and send the messages to Alice. Let's say that Bob is a bank, Alice a merchant and Carol a buyer. Usually Bob has to take some money from Carols account and after the he signals Alice, that she can give the goods to Carol. Now Carol wants to get the goods without paying and give a false signal to Alice (which Alice thinks is a signal from Bob). Both the public keys of Alice and Bob are well-known. One of the fields will be unique for every message, so that Carol can not use the same message to pay once and recieve the goods many times. The question is easy: how should I sign and encrypt the message? 1) calculate a digest (MD5, SHA) from the message, sign the digest (or should I sign the message contents + digest) with Bob's private key and encrypt it with Alice's public key? 2) is there any idea to generate a DES key, encrypt the message with the DES key, calculate a digest on (enc. message + DES key), sign the digest and encrypt it with Alice's public key? The message is small, so the time it takes to encrypt the message is not so important compared to higher speed of DES. 3) may be it would be good to encrypt the message with Alice's public key, then generate a digest, sign the digest and then once more encrypt the whole thing with Alice's public key? Using a DES session key helps in case someone would find out Alice's private key she uses to decrypt the message, but actually in this case it is not so important to hide the message contents (what is important are message integrity and sender authentication). What are the suggestions what crypto package might I use: RSAref, crypto++, SSLeay or some other? -- Juri Kaljundi jk(a)stallion.ee

Florida Supreme Court Home Page Adorned With Porn

Florida Supreme Court Home Page Adorned With Porn TALLAHASSEE, Fla (Reuter) - A Florida court's Web page was restored Friday after two days' absence following a break-in by a hacker who placed pornographic images on the site. Court officials Wednesday took the state court system home page off-line after a computer hacker apparently broke into the site and added pictures of nude men and women in various stages of sexual activity. The photos caused a stir among those who use the court page to access Florida Supreme Court and Appellate Court decisions. The home page is normally a little more staid, with a plain wood-grained background and hypertext links. Prurient, but disappointed, surfers looking for thrills on the net gave the court system home page one of its busiest days ever Friday. "We've had a significant number of hits today on our home page," said Craig Waters, executive assistant to Florida Supreme Court Chief Justice Gerald Kogan. "With all the publicity surrounding this, a lot of people are curious." No files were tampered with and court records remained intact, Waters said. The Florida Department of Law Enforcement was contacted and was investigating the break in. Court officials intend to prosecute the perpetrator, Waters said. ========================================== Blake Wehlage <jwilk(a)iglou.com> ±» RëVðLû¡ØÑ Bø+ ©ÖmP@ñ¥ «± Goto: http://members.iglou.com/jwilk *********PGP KEY On Request*********

Junkbusters: Invite the Government in!
by Ross Wright 17 Dec '03

17 Dec '03

QUOTE A direct quote from: http://www.junkbusters.com/ht/en/spam.html We think that junk email should be made illegal in the same way that junk faxes have been outlawed in the US. Unfortunately it will take lawmakers some time to get around to it, and even then spammers would probably try remailing through other jurisdictions to evade regulation. END QUOTE. I have only posted to this list RE: Internet Marketing and Spam. I have found that the general feeling runs against regulation of the internet. These Junkbuster people are crying for government intervention. The government coming into the internet is a bad idea. Therefore: Junkbusters is a bad idea.

Astrologer released after predicting death of Venezuela president By Vivian Sequera ASSOCIATED PRESS CARACAS, Venezuela - An astrologer who predicted 80 year-old President Rafael Caldera's "death" next year was released by political police Thursday after two days of questioning in detention. Jose Bernardo Gomez, 47, said he was detained "because I spoke about the possibility of the death of President Caldera." The widely feared Department of Intelligence and Prevention Services wanted to know where Gomez At his information, he said, and whether he was connected to leftist political groups. Caldera's astrological chart ,show that "Uranus is over the sun, Pluto is in ascendancy and Mars is going behind its moon" - not a good sign for the president, Gomez told police. "I've been sustaining the possibility of the death of the president of the republic for a long time," Gomez said, adding that the word "death" is "symbolic language that could be physical or something of another order." The arrest of the rotund, boarded and jovial 47-year old philosophy professor at Venezuela Central University was treated as front-page news by the mainstream daily newspaper El Nacional and other media. Government officials, perhaps a little embarrassed, played down the incident. "He's not accused of anything," Interior Minister Jose Guillermo Andueza said tersely. Political police merely wanted to know "what basis he has for making this kind of statement." Gomez, an academic with postgraduate degrees in history, education, psychology and philosophy from three Venezuela universities, said he meant Caldera no wrong and, in fact, voted for Caldera for his first term in 1968. "I wish the president good health. I'm not betting on his sicknesses, much less on his death," Gomez said in an interview in his home two hours after his release. "It's just that from an astrological point of view, 1997 looks dark for Caldera." Gomez spoke publicly on the topic at a conference of businessmen on Oct. 12.
