标准摘要
[中文适用范围]： ISO/IEC 20009 的这一部分指定了基于使用组公钥的签名的匿名实体身份验证机制，其中验证者验证组签名方案以验证与之通信的实体，而无需知道该实体的身份。 [外文原描述]： ISO/IEC 20009-2:2013 specifies anonymous entity authentication mechanisms based on signatures using a group public key in which a verifier verifies a group signature scheme to authenticate the entity with which it is communicating, without knowing this entity's identity. ISO/IEC 20009-2:2013 provides: a general description of an anonymous entity authentication mechanism based on signatures using a group public key; a variety of mechanisms of this type. ISO/IEC 20009-2:2013 describes: the group membership issuing processes; anonymous authentication mechanisms without an online Trusted Third Party (TTP); anonymous authentication mechanisms involving an online TTP. Furthermore, ISO/IEC 20009-2:2013 also specifies: the group membership opening process (optional); the group signature linking process (optional).
