Quizplus · Accepted Answer

HMACs (Hash-based Message Authentication Codes) provide cryptographic protection for authentication by ensuring that a message has been sent by a genuine source and has not been altered during transmission. They do not provide nonrepudiation, as they can be generated by anyone who possesses the shared secret key, not allowing for the sender to be uniquely identified or denying the sending of the message.
