In July 2023, NIST's Crypto Publication Review Board initiated a review of the following publications:
In September 2024, NIST proposed updating FIPS 202 and revising SP 800-185, in response to the public comments received on the decision proposal.
NIST has decided to update FIPS 202 to improve its editorial quality. Additionally, the text regarding SHA-1 and Triple DES will be updated to reflect the withdrawal of those techniques, as suggested in the public comments.
NIST has decided to revise SP 800-185 to provide “streaming” specifications of the two extendable output functions (XOFs) SHAKE128 and SHAKE256, to support implementations where the length of the data output and the complete input data may not be available before the XOF is called.
NIST will also consider other technical changes proposed in the public comments, in addition to editorial improvements.
The update of FIPS 202 and the revision of SP 800-185 will follow the standard process, including the release of a draft for public comment. Monitor progress on CSRC News and CSRC Publications, and by subscribing to email updates.
More details of this review are available at NIST’s Crypto Publication Review Project site.
