GB/T 15852.2-2012 Information technology—Security techniques—Message Authentication Codes (MACs)—Part 2:Mechanisms using a dedicated hash-function

Scope

This part of GB/T 15852 specifies three message authentication code algorithms using dedicated hash functions. These message authentication code algorithms can be used for data integrity verification to check whether the data has been unauthorizedly modified. Similarly, these message authentication code algorithms can also be used for message authentication to ensure the legitimacy of the message source. The strength of data integrity and message authentication depends on the length of the key and its confidentiality, the algorithmic strength of the hash function and its output length, the length of the message authentication code, and the specific message authentication code algorithm.
This part is applicable to the security services of any security architecture, process, or application.
