Blue Midnight Wish and NIST SHA-3 contest

·         I am one of the inventors of Blue Midnight Wish and one of the contributors of EDON-R hash functions in this contest. Blue Midnight Wish passed to the second round, it is the fastest candidate.

NIST Cryptographic Hash Algorithm Competition:

·         Main page is NIST SHA-3 contest. Unofficial pages: Zoo, wiki page, list of submitters, SW performance on eBASH, HW results, Niels Ferguson comparison.

·         On Oct. 31, 2008 - deadline for sending proposals. NIST received 64 entries.

·         On Dec.10, 2008 NIST accepted 51 First Round Candidates.

·         On Feb. 25-28, 2009 The First SHA-3 Candidate Conference was held in Leuven. 

·         On July 24, 2009 NIST selected the following 14 Second Round Candidates to continue in the competition: BLAKE, Blue Midnight Wish, CubeHash, ECHO, Fugue, Grøstl, Hamsi, JH, Keccak, Luffa, Shabal, SHAvite-3, SIMD, Skein. Submitters were invited to tweak their submissions by Sept. 15, 2009.

·         On September 28, 2009 NIST has published the tweaked versions of the algorithms on their page.

·         Nice summary of the tweaks is here.

·         NIST report summarizing the first round of the competition, and the selection of the second round candidates, is here.

·         Danilo Gligoroski showed that narrow-pipe SHA-3 candidates BLAKE, Hamsi, SHAvite-3 and Skein differ significantly from ideal random functions defined over big domains.  The paper "Narrow-pipe SHA-3 candidates differ significantly from ideal random functions defined over big domains" is available here. This result is further elaborated in:

·         Danilo Gligoroski, Vlastimil Klima: Practical consequences of the aberration of narrow-pipe hash designs from ideal random functions, IACR eprint, Report 2010/384, pdf.

·         the Second SHA-3 Candidate Conference is being planned for August 23-24, 2010, after Crypto 2010.
