CMAC Functions

The Intel IPP CMAC primitive functions use CMAC schemes based on block ciphers described in the Symmetric Cryptography Primitive Functions.

Table “Intel IPP CMAC Functions” lists the Intel IPP CMAC functions. A typical usage of the CMAC primitives is similar to the one of the Keyed Hash Functions.
