SHA-3 Standardization

Since announcing Keccak as the winning algorithm of the SHA-3 Cryptographic Hash Algorithm Competition on October 2, 2012, NIST has consulted with the Keccak design team and the cryptographic community in its effort to specify Keccak as the new SHA-3 Standard. The table below shows major events in the development of FIPS 202, SHA-3 StandardPermutation-Based Hash and Extendable-Output Functions.

Date Event
10/02/2012 SHA-3 competition ended; Keccak announced as the winner.
02/06/2013 Keccak team’s visit and presentation on SHA-3.
02/27/2013-11/01/2013 NIST shared SHA-3 standardization plans with cryptographic community at various events.
05/28/2014 Draft FIPS 202 announced in FRN 79 FR 30549. Revision to the Applicability Clause of FIPS 180-4 also proposed to allow the use of hash functions specified in either FIPS 180-4 or FIPS 202 for Federal applications that require a cryptographic hash function.
08/22/2014 SHA-3 Workshop at UCSB to obtain public feedback.
08/26/2014 Public comment period on Draft FIPS 202 ends. All comments are posted here.
