What serves as a message's authentication?

The property that a message has not been altered while in transit and that the receiving party can confirm the message's source is known as message authentication or data origin authentication in the field of information security.

Therefore, A message authentication code (MAC) is a cryptographic checksum on data that employs a session key to identify unintentional as well as intentional data modifications. A MAC needs two inputs: a message and a secret key that can only be known by the message's sender and intended recipient.
