Information technology — Security techniques — Anonymous entity authentication — Part 2: Mechanisms based on signatures using a group public key
信息技术——安全技术——匿名实体身份验证第2部分:基于使用组公钥的签名的机制
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.
