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..

Project need:

To align Canadian requirements with those of the respective international standards being proposed for adoption and to maintain alignment between Canadian information and communication technology standards and each respective international standard. This proposed New Standard is being developed at the request of P123 – Technical Committee on Information Technology. It will provide the industry with the latest standards available in the ICT field.
