CRYPT module

[sarun]

Hi Good day,

       Trying to understand the CRYPTO module for MAC generation, particularly AES CBS MAC. Which algorithm mode i have to choose?, found AES CBC not AES CBC MAC.

Hi @sarun 

We name it CCM for CBC-MAC. 

Please see section 37.4.15 of RM0399.

37.4.15 CRYP AES Counter with CBC-MAC (CCM)
