Blockchain for Access
Control Systems: Draft NISTIR 8403 Available for Comment
NIST has released NIST Internal Report (NISTIR) 8403, Blockchain for
Access Control Systems, for public comment.
Protecting system resources against unauthorized access is the
primary objective of an access control system. As information systems rapidly
evolve, the need for advanced access control mechanisms that support
decentralization, scalability, and trust – all major challenges for traditional
mechanisms – has grown.
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.
This document presents analyses of blockchain access control systems from the
perspectives of properties, components, architectures, and model supports, as
well as discussions on considerations for implementation.
The public comment period is open through February 7, 2022.
