A Review on Blockchain-based Access Control Models in IoT Applications
Yunpeng Zhang, Ali Memariani, Nirupam Bidikar · 2020
Conventional access control models such as RBAC and ABAC have been inefficient for IoT systems due to the raised security concerns. Blockchain technology has been effective to provide decentralized solutions for maintaining data, addressing the challenges of auditability, privacy, and scalability as well as eliminating a single point of failure problem in recent years IoT access control management. This work presents a review of access control frameworks using blockchain technology for IoT devices.
