CMAC is a Cipher-Based MAC that improves some of the security deficiencies
found in CBC-MAC. It is described in NIST SP800-38B as a mode of operation
for approved symmetric block chipers, namely AES and TDEA.
CMAC has similar use cases and security guarantees as HMAC, with the
difference that it uses a different primitive (symmetric cipher instead
of hash function).
CMAC may be appropriate for information systems in which an approved block
cipher is more readily available than an approved hash function.
Commonly it is used for symmetric key diversification (ASC X9 TR 31-2018),
data integrity assurance (ICV).
CMAC is public domain.
OP-TEE core already supports for AES CMAC, but not TDEA CMAC. This commit
adds TDEA CMAC support.
