NIST Announces SHA-3 Finalists (Skein is One of Them)
Yesterday, NIST announced the five hash functions to advance to the third (and final) round in the SHA-3 selection process: BLAKE, Grøstl, JH, Keccak, and Skein. Not really a surprise; my predictions—which I did not publish—listed ECHO instead of JH, but correctly identified the other four. (Most of the predictions I saw guessed BLAKE, Grøstl, Keccak, and Skein, but differed on the fifth.)
NIST will publish a report that explains its rationale for selecting the five it did.
Next is the Third SHA-3 Candidate Conference, which will probably be held in March 2012 in Washington, DC, in conjunction with FSE 2012. NIST will then pick a single algorithm to become SHA-3.
More information about Skein and the SHA-3 selection process, including lots of links, is here. Version 1.3 of the Skein paper, which discusses the new constant to defeat the Khovratovich-Nikolié-Rechberger attack, is here (description of the tweak here). And there’s this new analysis of Skein.
And if you ordered a Skein polo shirt in September, they’ve been shipped.
