Blockchain for access control systems

Abstract

The rapid development and wide application of distributed network systems have made network security especially access control and data privacy ever more important. Blockchain technology offers features such as decentralization, high confidence, and tamper-resistance, which are advantages to solving auditability, resource consumption, scalability, central authority, and trust issues all of which are challenges for network access control by traditional mechanisms. This document presents general information for blockchain access control systems from the views of blockchain system properties, components, functions, and supports for access control policy models. Considerations for implementing blockchain access control systems are also included.
