CMAC

CMAC stands for "Cipher-based Message Authentication Code". It is a type of encryption that is used to securely store and transfer data. With CMAC, data is first encrypted with a secret code, called a cipher. This creates an encrypted version of the data which is then sent across a network. When the data is received, the receiver can use their special code to decrypt the data, ensuring it is the same as when it was originally sent. This is a very secure way of handling sensitive data, as the code is not visible to anyone except the sender and receiver.
