CSA ISO/IEC 20008-2:21

1 Scope This part of ISO/IEC 20008 specifies anonymous digital signature mechanisms, in which a verifier makes use of a group public key to verify a digital signature. It provides — a general description of an anonymous digital signature mechanism using a group public key, and — a variety of mechanisms that provide such anonymous digital signatures. For each mechanism, this part of ISO/IEC 20008 specifies — the process for generating group member signature keys and a group public key, — the process for producing signatures, — the process for verifying signatures, — the process for opening signatures (if the mechanism supports opening), — the process for linking signatures (if the mechanism supports linking), and — the process for revoking group members.
