《GB/T 15843.3-2008信息技术 安全技术 实体鉴别 第3部分: 采用数字签名技术的机制》由TC260（全国网络安全标准化技术委员会）归口，主管部门为国家标准化管理委员会。
本部分规定了采用数字签名技术的实体鉴别机制。有两种鉴别机制是单个实体的鉴别（单向鉴别），其余的是两个实体的相互鉴别机制。

Scope

This part 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 random numbers to prevent previous authentication information from being accepted later or accepted multiple times. If timestamps or sequence numbers are used, only one pass is required for single-phase authentication, while two passes are required for mutual authentication. If a stimulus-response approach using random numbers is used, two passes are required for one-way authentication, and three or four passes (depending on the mechanism used) for mutual authentication.
