In August 2021, NIST's Crypto Publication Review Board initiated a review process for Federal Information Processing Standard (FIPS) 198-1 The Keyed-Hash Message Authentication Code (HMAC) and received public comments.
NIST has decided to convert FIPS 198-1 to a new Special Publication, NIST SP 800-224, and will revise the text to:
FIPS 198-1 will be withdrawn after the new SP is published. Note that the conversion of a FIPS to an SP is not expected to impact the validation process.
The effort to develop NIST SP 800-224 has not yet begun, but it will follow the typical process where a draft is first posted for public comment. Monitor progress on CSRC News and CSRC Publications, and by subscribing to email updates.
