In cryptography, a message authentication code (MAC), sometimes known as a tag, is a short piece of information used to authenticate a message—in other words, to confirm that the message came from the stated sender (its authenticity) and has not been changed. As defined in RFC 6238, TOTP is an extension of the OTP algorithm, namely the Hashed Message Authentication Code (HMAC)–based one-time password (HOTP) algorithm, to support a time-based moving factor. A message authentication code function is evaluated based on the secret key to produce an output value. An HMAC is a digest used to verify the authenticity of a message. A MAC takes a variable-length message and a secret key as input and produces an authentication code. If you could change the message the authentication tag should become invalid. It is hard to have message authenticity without integrity. A recipient in possession of the secret key can generate an authentication code to verify the integrity of the message. 108 synonyms for board: blackboard, noticeboard, chalkboard, flip chart, whiteboard, plank, panel, timber, piece of wood, slat, piece of timber, lath....
