1 Scope
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.
