NIST Releases Draft Report on Blockchain for Access Control Systems for Public Comment

On December 20, 2021, The National Institute of Standards and Technology (NIST) released its draft interagency report 8403 on “Blockchain for Access Control Systems”.  As the report’s abstract states:

“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.”

This public review also includes a call for information on essential patent claims (see page iv of the draft report). For more information regarding inclusion of patents in Information Technology Laboratory (ITL) publications, click here.

The draft NISTIR discusses, among other things: (a) blockchain system component and advantages for access control systems, (b) access control functions of blockchain access control systems; (c) access control model support, and (d) other considerations.

The public comment period lasts from December 20, 2021 through February 7, 2022.
