Scope

This document specifies entity authentication mechanisms using a cryptographic check
function, including unilateral authentication and bidirectional authentication mechanisms.
This document is applicable to the design, development, implementation and testing, etc. of
entity authentication using a cryptographic check function.
The mechanisms specified in this document use time variant parameters, such as time stamps,
sequence numbers or random numbers to prevent the problem that previously valid
authentication information is accepted again after it has expired.
If time stamps or sequence numbers are used, unilateral authentication requires only one
transfer, while bidirectional authentication requires two transfers. If the challenge-response
method of random numbers is used, unilateral authentication requires two transfers, and
bidirectional authentication requires three transfers.
For examples of cryptographic check function, see GB/T 15852 (all parts).
