Description

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.
