NIST is holding a competition to replace the SHA family of hash functions, which have been increasingly under attack.
…
NIST’s deadline is Friday. It seems as if everyone — including many amateurs — is working on a hash function, and I predict that NIST will receive at least 80 submissions. (Compare this to the 21 submissions NIST received — five were rejected as not being complete — for the AES competition in 1998.) I expect people to start posting their submissions over the weekend. (Ron Rivest already presented MD6 at Crypto in August.) Probably the best place to watch for new hash functions is here; I’ll try to keep a listing of the submissions myself.
"Schneier on Security: The Skein Hash Function. This could be even more fun to watch than AES was. Hmm, with all those amateur submissions, perhaps some amateur cryptanalysis is in order?
