Information technology. Security techniques. Anonymous entity authentication. Mechanisms based on signatures using a group public key | Status: Confirmed, Current

1 Scope This part of ISO/IEC 20009 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. This part of ISO/IEC 20009 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.

This part of ISO/IEC 20009 describes

• — the group membership issuing processes;
• — anonymous authentication mechanisms without an online Trusted Third Party (TTP);
• — anonymous authentication mechanisms involving an online TTP.

Furthermore, this part of ISO/IEC 20009 also specifies

• — the group membership opening process (optional);
• — the group signature linking process (optional).
