适用范围：This part of ISO/IEC 9797 specifies six MAC algorithms that use a secret key and an n-bit block cipher to calcu- late an m-bit MAC. These mechanisms can be used as data integrity mechanisms to verify that data has not been altered in an unauthorised manner. They can also be used as message authentication mechanisms to pro- vide assurance that a message has been originated by an entity in possession of the secret key.
