This standard specifies a Data Authentication Algorithm (DAA) which may be used to detect unauthorized modifications, both intentional and accidental, to data, The standard is based on the algorithm specified in the Data Encryption Standard (DES) Federal Information Processing Standards Publication (FIPS PUB) 46, and is compatible with both the Department of the Treasury's Electronic Funds and Security Transfer Policy and the American National Standards Institute (ANSI) Standard for Financial Institution Message Authentication (see cross index). The Message Authentication Code (MAC) as specified in ANSI X9.9 is computed in the same manner as the Data Authentication Code (DAC) specified in this standard. Similarly, the Data Identifier (DID) specified in this standard is sometimes referred to as a Message Identifier (MID) in standards related to message communications.
