ISO/IEC 20008-2:2013

ISO/IEC 20008-2:2013 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; a variety of mechanisms that provide such anonymous digital signatures. For each mechanism, ISO/IEC 20008-2:2013 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); the process for revoking group members.
