ISO/IEC JTC 1/SC 27 9797-2:2011 Message Authentication Codes (MACs) - Part 2: Mechanisms using a dedicated hash-function

SCOPE

This part of ISO/IEC 9797 specifies three MAC algorithms that use a secret key and a hash-function (or its round-function) with an n-bit result to calculate an m-bit MAC. These mechanisms can be used as data integrity mechanisms to verify that data has not been altered in an unauthorized manner. They can also be used as message authentication mechanisms to provide assurance that a message has been originated by an entity in possession of the secret key.
