Recommendation for Block Cipher Modes of Operation: Galois/Counter Mode (GCM) and GMAC

Published

Author(s)

Morris J. Dworkin

Abstract

This Recommendation specifies the Galois/Counter Mode (GCM), an algorithm for authenticated encryption with associated data, and its specialization, GMAC, for generating a message authentication code (MAC) on data that is not encrypted. GCM and GMAC are modes of operation for an underlying approved symmetric key block cipher.
