PMAC (cryptography)

PMAC, which stands for Parallelizable MAC, is a message authentication code algorithm. It was created by Phillip Rogaway (patent pending).

PMAC is a method of taking a block cipher and creating an efficient message authentication code that is provably reducible in security to the underlying block cipher.

PMAC is similar in functionality to the OMAC algorithm.
