WebJan 1, 2024 · A CMAC is a message authentication code similar to an hmac but it uses a block cipher instead of a message digest function. The secret key (K) is the same key that you use to encrypt the message. This adds n+1 blocks to the cipher text. In my scenario this prevents both attacks 1 and 2. WebIntroduction The National Institute of Standards and Technology (NIST) has recently specified the Cipher-based Message Authentication Code (CMAC).
