What is a MAC tag and how does it work?
What will be an ideal response?
Message Authentication Code (MAC), also known as Message Integrity Check (MIC), uses a shared secret key that is agreed on by the sender and receiver in the verification process to
generate a MAC tag for a message. A MAC tag is like an enhanced message digest. The shared secret key adds a measure of security to the hashing algorithm. The message and MAC tag are sent to the receiver. The key is also sent to the receiver securely; this key is usually sent separately from the message. The receiver goes through the same process of using the transmitted message and key to generate a MAC tag, and compares this tag with the one received in the message to confirm the message's integrity and authenticity. The verification process is protected by secure communication of the key, which ensures that the sender and receiver generate the same MAC tag from the message.
