Crypto breakthrough shows Flame was designed by world-class scientists | Ars Technica

2012 Jun 7, 9:12

So this is another Stuxnet by Israel/US?

The analysis reinforces theories that researchers from Kaspersky Lab, CrySyS Lab, and Symantec published almost two weeks ago. Namely, Flame could only have been developed with the backing of a wealthy nation-state. … “It’s not a garden-variety collision attack, or just an implementation of previous MD5 collisions papers—which would be difficult enough,” Matthew Green, a professor specializing in cryptography in the computer science department at Johns Hopkins University, told Ars. “There were mathematicians doing new science to make Flame work.”

RFC 5843 - Additional Hash Algorithms for HTTP Instance Digests

2010 Apr 21, 6:51Adds SHA 256 & 512 to HTTP instance digest: 'The IANA registry named "Hypertext Transfer Protocol (HTTP) Digest Algorithm Values" defines values for digest algorithms used by Instance Digests in HTTP. Instance Digests in HTTP provide a digest, also known as a checksum or hash, of an entire representation of the current state of a resource. This document adds new values to the registry and updates previous values.'PermalinkCommentshash cryptography http instance-digest sha security technical ietf rfc standard

(in which a rubber hose is applied forcefully and frequently to the soles of the feet until the key to the cryptosystem is discovered, a process that can take a surprisingly short time and is quite computationally inexpensive)"PermalinkCommentshumor cryptography rubber-hose security
