CMAC (Cipher-based Message Authentication Code): A cryptographic technique for message authentication using a symmetric key block cipher algorithm such as AES. It provides integrity and authenticity for messages or data by producing a fixed-size output, known as a tag or MAC, which is sent along with the message. The receiver then computes the CMAC using the same secret key to verify the integrity of the message. CMAC is resistant to forgery and is widely used in various security protocols and applications.
