ISO/IEC 20008-3:2024

OVERVIEW

This document specifies anonymous digital signature mechanisms in which a verifier uses multiple public keys to verify a digital signature.

This document provides:

—     a general description of an anonymous digital signature mechanism using multiple public keys;

—     a variety of mechanisms that provide such anonymous digital signatures.

For each mechanism, this document specifies the process for:

—     generating the private key and public key of each user;

—     producing signatures;

—     verifying signatures;

—     linking signatures (if the mechanism supports linking);

—     tracing signatures (if the mechanism supports tracing);

—     producing signatures with threshold capability (if the mechanism supports a threshold capability);

—     verifying signatures with threshold capability (if the mechanism supports a threshold capability).

This document does not define the implementation of a public key infrastructure (PKI) and the means for distinct entities to exchange, extract and verify their respective public key certificates.
