Hi All,
ISO/IEC just published ISO/IEC 20008-3:2024 Information security - Anonymous digital signatures Part 3: Mechanisms using multiple public keys
his 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.
