Message Authentication Code - Data associated with an authenticated message allowing a receiver to verify the integrity of the message.

FIPS 201-1

Message Authentication Code (MAC) - A cryptographic checksum on data that uses a symmetric key to detect both accidental and intentional modifications of the data.

NIST IR 7298

Message Authentication Code (MAC) - A cryptographic checksum that results from passing data through a message authentication algorithm. SOURCE: FIPS 198

NIST SP 800-107

Message Authentication Code (MAC) - A fixed length bit string, computed by a MAC algorithm, that is used to establish the authenticity and, hence, the integrity of a message.

NIST SP 800-108

Message Authentication Code - A family of cryptographic algorithms that is parameterized by a symmetric key. Each of the algorithms can act on input data of arbitrary length to produce an output value of a specified length (called the MAC of the input data). A MAC algorithm can be used to provide data origin authentication and data integrity.

NIST SP 800-38B

Message Authentication Code (MAC) - A bit string of fixed length, computed by a MAC generation algorithm, that is used to establish the authenticity and, hence, the integrity of a message.

NIST SP 800-38C

Message Authentication Code (MAC) - A cryptographic checksum on data that is designed to reveal both accidental errors and intentional modifications of the data.

NIST SP 800-57P1

Message Authentication Code (MAC) - A cryptographic checksum on data that uses a symmetric key to detect both accidental and intentional modifications of data.

NIST SP 800-63v1.0.2

Message Authentication Code (MAC) - A cryptographic checksum on data that uses a symmetric key to detect both accidental and intentional modifications of the data.
