Scope

This part of GB/T 15843 specifies the entity authentication mechanism using digital signature technology. Two authentication mechanisms are authentication of a single entity (one-way authentication), and the rest are mutual authentication mechanisms of two entities. The mechanisms specified in this standard use time-varying parameters such as timestamps, sequence numbers or nonces to prevent previously valid authentication information from being later accepted or accepted more than once. If timestamps or serial numbers are used, only one pass is required for one-way authentication, and two passes are required for mutual authentication. If the random number challenge-response method is used, two passes are required for one-way authentication, and three passes, two passes in parallel, or five passes (depending on the mechanism used) are required for mutual authentication. This section applies to all applications and equipment that require authentication.
