This Recommendation specifies an algorithm called Galois/Counter Mode (GCM) for authenticated encryption with associated data. GCM is constructed from an approved symmetric key block cipher with a block size of 128 bits, such as the Advanced Encryption Standard (AES) algorithm that is specified in Federal Information Processing Standard (FIPS) Pub. 197 [2]. Thus, GCM is a mode of operation of the AES algorithm.
