Message Authentication Functions
Hash function-based MAC (HMAC) is widely used in the applications requiring message authentication and data integrity check. HMAC was initially put forward in [RFC 2401] and adopted by ANSI X9.71 and [FIPS PUB 198]. See Keyed Hash Functions for a description of the Intel® Integrated Performance Primitives (Intel® IPP) HMAC primitives.
A MAC algorithm based on a symmetric key block cipher, in other words, a cipher-based MAC (CMAC), is standardized in [NIST SP 800-38B]. CMAC may be appropriate for information systems where an approved block cipher is available rather than an approved hash function. See CMAC Functions for a description of the Intel IPP CMAC primitives.
