A MAC algorithm is a family of cryptographic functions – parameterized by a symmetric key – that can be used to provide data origin authentication, as well as data integrity, by producing a MAC tag on arbitrary data (the message).
What algorithm does MAC use?
The algorithm used to generate and verify the MAC is based on the DES. A keyed Hash Message Authentication Code (HMAC) is an extension to the MAC function to include cryptographic hash function and a secret key in deriving the message authentication code.
How many algorithms are there in MAC?
Currently, there are three (3) approved* general purpose MAC algorithms: HMAC, KMAC and CMAC.
