MESSAGE AUTHENTICATION CODE ALGORITHM
Data Authentication Code; FIPS PUB 113

Message authentication         
IN INFORMATION SECURITY
Data authenticity; Authenticity (information security); Data origin authentication; Data-origin authentication; Data Origin Authentication; Message Authentication; Data Authentication; Data authentication; Data origin authenticity; Message authenticity; Data-origin authenticity; Cryptographitcally authenticated; Cryptographic authentication; Cryptographically authenticated
In information security, message authentication or data origin authentication is a property that a message has not been modified while in transit (data integrity) and that the receiving party can verify the source of the message. Message authentication does not necessarily include the property of non-repudiation.

(DES) The NBS's popular, standard encryption algorithm. It is a product cipher that operates on 64-bit blocks of data, using a 56-bit key. It is defined in FIPS 46-1 (1988) (which supersedes FIPS 46 (1977)). DES is identical to the ANSI standard Data Encryption Algorithm (DEA) defined in ANSI X3.92-1981. DES has been implemented in VLSI. SunOS provides a des command which can make use of DES hardware if fitted. Neither the software nor the hardware are supposed to be distributed outside the USA. Unix manual pages: des(1), des(3), des(4). (1994-12-06)

Data Authentication Algorithm

The Data Authentication Algorithm (DAA) is a former U.S. government standard for producing cryptographic message authentication codes. DAA is defined in FIPS PUB 113, which was withdrawn on September 1, 2008. The algorithm is not considered secure by today's standards. According to the standard, a code produced by the DAA is called a Data Authentication Code (DAC). The algorithm chain encrypts the data, with the last cipher block truncated and used as the DAC.

The DAA is equivalent to ISO/IEC 9797-1 MAC algorithm 1, or CBC-MAC, with DES as the underlying cipher, truncated to between 24 and 56 bits (inclusive).
