This part of ISO/IEC 9797 specifies six MAC algorithms that use a secret key and an n-bit block cipher to calculate an m-bit MAC.
 

This part of ISO/IEC 9797 can be applied to the security services of any security architecture, process, or application.
 

Key management mechanisms are outside the scope of this part of ISO/IEC 9797.

 

This part of ISO/IEC 9797 specifies object identifiers that can be used to identify each mechanism in accordance with ISO/IEC 8825-1. Numerical examples and a security analysis of each of the six specified algorithms are provided, and the relationship of this part of ISO/IEC 9797 to previous standards is explained.
