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
The document contains a corrected version of Appendix D of Special Publication 800-38B, which specifies examples for the CMAC authentication mode. In particular, the values of the MAC, T, for Examples 14, 15, 18, and 19 have been corrected
