PMAC (cryptography)
From Wikipedia, the free encyclopedia
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.
