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.
