Draft FIPS 198-1 is the proposed revision of FIPS 198. The draft specifies a keyed-hash message authentication code (HMAC), a mechanism for message authentication using cryptographic hash functions and shared secret keys. Security issues related to the HMAC algorithm, and its applications and truncation technique are addressed in NIST Special Publication 800-57, Recommendation for Key Management, and draft NIST Special Publication 800-107, Recommendation for Using Approved Hash Algorithms. Draft NIST Special Publication 800-107 will be available in the near future.
