Sécurité de l’information — Signatures numériques anonymes — Partie 3: Mécanismes utilisant plusieurs clés publiques

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.
