Cryptographic experts at the Crypto 2006 conference have demonstrated a modified method of attack against a reduced variant of the SHA-1 hash algorithm. The new method is an attack which, for the first time, allows at least a part of the message to be freely selected, for example as straight text. Previous approaches, for example the collision attack by Xiaoyun Wang and her team, which attracted considerable attention, were merely able to produce almost completely different hash twins of the same length, both consisting of meaningless gibberish. .

There has been a great deal of difficulty experienced in getting research performed by cryptographers in the last decade or so (beyond basic algorithms such as SHA and AES) applied in practice. The reason for this is that cryptographers don't work on things that implementors need because it's not cool, and implementors don't use what cryptographers design because it's not useful or sufficiently aligned with real-world considerations to be practical. As a result, security standards are being created with mechanisms that have had little or no security analysis, often homebrew mechanisms or the standards editor's pet scheme. The problem is a lack of communication: Cryptographers often don't seem aware of the real-world constraints that their design will need to work within in order to be successfully deployed. The intent of this document is to cover some of those real-world constraints for cryptographers, to point out problems that their designs will run into when attempts are made to deploy them. Also included is a motivational list of extremely uncool problems that implementors have been building ad-hoc solutions for since no formal ones exist. "Looking at all of the security protocols deployed in the last 10 years, you'd be forgiven for thinking that the only developments in crypto during that time (beyond basic algorithms) were HMAC and SPEKE" The link for this article located at Peter Gutmann is no longer available. .

A computer science professor is renewing a constitutional challenge to U.S. encryption laws, arguing that the government's policy on restricting the export of domestic cryptographic research violates the First Amendment. Daniel Bernstein, the University of Illinois computer science professor who resurrected the lawsuit in a San Francisco district court on Monday, said he is only trying to help protect computer systems against terrorists and other criminals. "It's inexcusable that the government is continuing to interfere with my research in cryptography and computer security," Bernstein said. Until very recently, the U.S. government severely restricted the export of domestic information-scrambling products and know-how. To the government's way of thinking, once such leading-edge technology has made its way into the hands of terrorists, the bad guys could then effectively keep American intelligence agencies in the dark.
