Please be advised that a New Work Item Proposal has been loaded to the BSI Standards Development Portal for comment.
Any comments received will be submitted to the national committee “IST/33 – Information security, cybersecurity and privacy protection” for consideration when deciding the UK response to the associated Standards Development Organisation.
Proposal link: ISO/IEC NP 24843 – Information security — Attribute-Based Credentials
Comment period end date: 06/02/2025
Scope
This document specifies attribute-based credential (ABC) mechanisms. It defines the parties participating in such mechanisms and their respective roles, the set of protocols that constitute such mechanisms along with a set of additional processes that they may support to provide additional features, as well as the security properties to be satisfied by such schemes.
Purpose
Attribute-based credential (a.k.a. anonymous credential) is a major cryptographic primitive that enhances digital signatures by offering users a perfect control of their personal data. Concretely, an ABC is essentially a signature generated on potentially hidden data that can be used to attest validity of any subset of those data, with very high privacy assurances. As such, it is a natural tool to comply with ever more stringent privacy regulations as, for example, GDPR.
