Scope

This part of GB/T 15843 specifies an entity authentication mechanism using a symmetric encryption algorithm. Four of them are inaccessible between two entities
Trust the third-party authentication mechanism. Two of the four mechanisms are one-way authentication by one entity against another entity, and the other two are two-way authentication mechanisms.
Two entities authenticate each other. The rest of the mechanisms require a trusted third party to participate in order to establish a public secret key to achieve mutual or single
Entity identification.
The mechanisms specified in this section use time-varying parameters such as timestamps, serial numbers, or random numbers to prevent previously valid authentication information from being
Accepted or accepted multiple times.
If there is no trusted third party involved and a timestamp or serial number is used at the same time, the information only needs to be transmitted once for one-way authentication.
Mutual authentication needs to be sent twice. If there is no trusted third party involved and the challenge-response method using random numbers is used, one-way authentication
Don't need to transmit information twice, and for mutual authentication, you need to transmit three times. If there is a trusted third party involved, between an entity and the trusted third party
Any additional communication of the need to add two transfers in the communication exchange.
