Recommendation for Block Cipher Modes of Operation: The CMAC Mode for Authentication

Author(s)
Abstract
This Recommendation specifies a message authentication code (MAC) algorithm based on a symmetric key block cipher. This block cipher-based MAC algorithm, called CMAC, may be used to provide assurance of the authenticity and, hence, the integrity of binary data.
