Jul 16, 2008 · This Standard describes a keyed-hash message authentication code (HMAC), a mechanism for message authentication using cryptographic hash functions. HMAC can be used with any iterative Approved cryptographic hash function, in combination with a shared secret key.

Message authentication is achieved via the construction of a message authentication code (MAC). MACs based on cryptographic hash functions are known as. HMACs. The purpose of a MAC is to authenticate both the source of a message and its integrity without the …

Jan 4, 2017 · Currently, there are three (3) approved * general purpose MAC algorithms: HMAC, KMAC and CMAC. NIST SP 800-224, Keyed-Hash Message Authentication Code (HMAC): Specification of HMAC and Recommendations for Message Authentication (Initial Public Draft) was released for public comment on June 28, 2024.

An HMAC function is used by the message sender to produce a value (the MAC) that is formed by condensing the secret key and the message input. The MAC is typically sent to the message receiver along with the message. The receiver computes the MAC on the received message using the same key and HMAC function as was used by the sender, and

Overview: The Keyed-Hash Message Authentication Code (HMAC) is specified in FIPS 198 dated March 6, 2002, Keyed-Hash Message Authentication Code (HMAC). This algorithm utilizes the Secure Hash Algorithms as an underlying primitive. Testing Requirements: CMT labs can test for conformance to the HMAC algorithm in FIPS 198.

using HMAC for message authentication, including a list of NIST-approved cryptographic 89 hash functions, requirements on the secret key, and parameters for optional truncation.
