The ANSI standard for a keyed hash function that is equivalent to DES cipher block chaining with IV = 0. [A9009]
The ANSI standard for a keyed hash function that is equivalent to DES cipher block chaining with IV = 0. [A9009]
Synonym for some kind of "checksum".
Deprecated Term: IDOCs SHOULD NOT use the uncapitalized form "data authentication algorithm" as a synonym for any kind of checksum, regardless of whether or not the checksum is based on a hash. Instead, use "checksum", "Data Authentication Code", "error detection code", "hash", "keyed hash", "Message Authentication Code", "protected checksum", or some other specific term, depending on what is meant.
The uncapitalized term can be confused with the Data Authentication Code and also mixes concepts in a potentially misleading way. The word "authentication" is misleading because the checksum may be used to perform a data integrity function rather than a data origin authentication function.
