Message Authentication Code Definition: A Message Authentication Code (MAC) is a cryptographic checksum used to authenticate the integrity and origin of a message, ensuring that it has not been altered during transmission.
Message Authentication Code (MAC) is a cryptographic checksum that is generated by applying a secret key to a message. It is used to verify the integrity and authenticity of transmitted data. A MAC ensures that a message has not been altered or tampered with during transmission and provides a way to authenticate the sender of the message.
Message Authentication Code is one of the topics you'll master in the Security+ Boot Camp.
