Abstract

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.
