ISO 8731 specifies, in individual parts, approved authentication algorithms i.e. approved as meeting the authentication requirements specified in ISO 8730. This part of ISO 8731 deals with the Message Authenticator Algorithm for use in the calculation of the Message Authentication Code (MAC).
The Message Authenticator Algorithm (MAA) is specifically designed for high speed authentication using a mainframe computer. This is a special purpose algorithm to be used where data volumes are high, and efficient implementation by Software a desirable characteristic. MAA is also suitable for use with a programmable calculator.
Test examples are given in an annex, which does not form part of this International Standard.
