Blockchain based access control systems: State of the art and challenges
This is an incremental survey paper for researchers and practitioners interested in blockchain applications for access control.
The paper reviews problems in current access control systems, such as third-party reliance and inefficiency, and explores how blockchain technology can address these issues, presenting an overview of studies and platforms across domains.
Access to the system resources. The current access control systems face many problems, such as the presence of the third-party, inefficiency, and lack of privacy. These problems can be addressed by blockchain, the technology that received major attention in recent years and has many potentials. In this study, we overview the problems of the current access control systems, and then, we explain how blockchain can help to solve them. We also present an overview of access control studies and proposed platforms in different domains. This paper presents the state of the art and the challenges of blockchain-based access control systems.
