Plus of course some sort of assurance that skype's crypto isn't snakeoil :) It is snake oil until proven otherwise. Yup. They say they use AES, and that they use RSA to set up session keys. The main issue is that they don't document their protocols or crypto, and of course the usual failures are bad protocol design, which can break systems that do include strong crypto. The use of RSA for session key setup instead of Diffie-Hellman is a strong sign that they don't really have a clue... If you're in the SF Bay Area, Skype is having a developer get-together in Palo Alto on Thursday 9/22. http://www.skype.com/campaigns/skypenightpaloalto2005

The FBI is Having Trouble on the Line, Notebook, August 15) is in error. You claim that police can't tap into [Internet] conversations or identify the location of callers, even with court orders. That is false. Internet service providers and VoIP companies have consistently responded to such orders and turned over information in their possession. There is no evidence that law enforcement is having any trouble obtaining compliance. But more disturbingly, you omit entirely any reference to the grave threat these FBI initiatives pose to the personal privacy and security of innocent Americans. The technologies currently used to create wiretap-friendly computer networks make the people on those networks more pregnable to attackers who want to steal their data or personal information. And at a time when many of our most fundamental consititutional rights are being stripped away in the name of fighting terrorism, you implicitly endorse opening yet another channel for potential government abuse. The legislative history of the Communications Assistance for Law Enforcement Act (CALEA) shows that Congress recognized the danger of giving law enforcement this kind of surveillance power in the face of increasingly powerful and personally revealing technologies (H.R. Rep. No. 103-827, 1994 U.S.C.C.A.N. 3489, 3493 [1994] [House Report]). The law explicitly exempts so-called information services; law enforcement repeatedly assured civil libertarians that the Internet would be excluded. Yet the FBI and FCC have now betrayed that promise and stepped beyond the law, demanding that Internet software be redesigned to facilitate eavesdropping. In the coming months, we expect the federal courts to rein in these dangerously expansive legal intepretations. -- Seth Schoen Staff Technologist[EMAIL PROTECTED] Electronic Frontier Foundationhttp://www.eff.org/ 454 Shotwell Street, San Francisco, CA 94110 1 415 436 9333 x107 - You are subscribed as [EMAIL PROTECTED] To manage your subscription, go to http://v2.listbox.com/member/?listname=ip Archives at: http://www.interesting-people.org/archives/interesting-people/ - End forwarded message - -- Eugen* Leitl a href=http://leitl.org;leitl/a __ ICBM: 48.07100, 11.36820http://www.leitl.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE [demime 1.01d removed an attachment of type application/pgp-signature which had a name of signature.asc]
