NIST has published NIST Internal Report (NIST IR) 8403, Blockchain for Access Control Systems, providing guidance for organizations looking to blockchain as a method of improving security.
The guide states that blockchain technology offers high confidence and tamper resistance implemented in a distributed fashion without a central authority, which means that it can be a trustable alternative for enforcing access control policies.
Blockchain for Access Control Systems presents an analysis of blockchain access control systems ‘from the perspectives of properties, components, architectures, and model supports, as well as discussions on considerations for implementation’.
