Full title and description

ISO/IEC 18370-1:2016 — Information technology — Security techniques — Blind digital signatures — Part 1: General. This part defines the general principles, terminology, models and high-level requirements for blind digital signature mechanisms and their variants (partial disclosure, selective disclosure and traceable blind signatures) used in privacy-preserving authentication and related applications.

Abstract

Part 1 of ISO/IEC 18370 specifies principles, a general model, a set of entities, processes and general requirements for blind digital signature mechanisms. It describes variants including blind signature mechanisms with partial disclosure, with selective disclosure and traceable blind signature mechanisms. It also contains the terms, definitions, abbreviated terms and figure elements used across the ISO/IEC 18370 series and includes an annex comparing the variants.

Scope

This part establishes the general framework and foundational requirements for blind digital signature mechanisms. It defines the actors, data objects and processes relevant to issuing, presenting and verifying blind signatures and sets out general security and functional requirements that apply to the mechanisms and their variants. It is intended to be referenced by the normative parts that specify concrete algorithms and mechanism families.

Key topics and requirements

• Terminology and definitions for blind digital signatures and related concepts.
• General model describing entities (requestor, signer, verifier, trusted parties), data elements and process flows.
• General security and functional requirements for blind signature mechanisms (privacy, unforgeability, non-repudiation and optional traceability controls).
• Variants specification: partial disclosure (partially blind signatures), selective disclosure, and traceable blind signatures.
• Requirements for presentation and verification processes where selective disclosure is supported.
• Guidance on optional tracing and related evidence evaluation for traceable mechanisms.
• Annex with comparison of the blind signature mechanism variants.

Typical use and users

Used by standards developers, cryptographic protocol designers, security engineers and implementers creating privacy-preserving systems (for example e‑cash, anonymous credentials, privacy-preserving authentication and certain e‑voting schemes). Also relevant to researchers, evaluators, certification bodies and organizations specifying higher-level application protocols that rely on blind signature primitives.

Related standards

Primary related work includes ISO/IEC 18370-2 (Discrete logarithm based mechanisms) which specifies concrete mechanisms; other related ISO/IEC standards on digital signatures and anonymous signatures (for example ISO/IEC standards on digital signatures with appendix and anonymous signature families), and standards on key management and cryptographic primitives used by signature mechanisms. Work from ISO/IEC JTC 1/SC 27 (IT security techniques) is the technical context for this series.

FAQ

Q: What is this standard?

A: ISO/IEC 18370-1:2016 is the general, introductory part of the ISO/IEC 18370 series that defines the principles, models, terminology and high-level requirements for blind digital signature mechanisms.

Q: What does it cover?

A: It covers the conceptual model, entities, processes and general security/functional requirements for blind digital signatures and their variants (partial disclosure, selective disclosure and traceable blind signatures), plus common terms and figure elements used across the series.

Q: Who typically uses it?

A: Cryptographers, protocol designers, security engineers, implementers of privacy-preserving systems (e‑cash, anonymous credentials, selective-disclosure credentials), standards developers, evaluators and certification bodies.

Q: Is it current or superseded?

A: It was published in November 2016 (Edition 1) and was subject to ISO systematic review and confirmed in 2022; it remains the current Part 1 of the ISO/IEC 18370 series unless a later revision is published.

Q: Is it part of a series?

A: Yes — ISO/IEC 18370 is a multi-part series. Part 1 is the general framework; other parts (for example Part 2) specify concrete mechanism families (discrete-logarithm based mechanisms) and implementation details.

Q: What are the key keywords?

A: Blind digital signature, partially blind signature, selective disclosure, traceability, anonymity, unlinkability, privacy, digital signature mechanisms.
