【Abstract】The dramatic rise in internet-based service provisioning has highlighted the importance of deploying scalable access control methods, facilitating service authorization for eligible users. Existing centralized methods suffer from single-point-of-failure, low scalability, and high computational overhead. In addition, in these methods, users pay for the service provider as well as the network provider independently for a specific service, imposing extra cost for the user. New business models are needed to resolve such shortcomings. The realization of these models calls for sophisticated access control methods which consider the requirements of all parties who want to: 1) access a service; 2) provide that service; and 3) provide the network connection. Blockchain is an enabling technology that provides unprecedented opportunities to novel distributed access control methods for new business models. We propose an Attribute-based access control solution by leveraging Blockchain to share network providers' and service providers' resources. Our solution offers access flexibility based on the requirements of the parties while fulfilling reliability, accountability, and immutability. Besides, it decreases the overall service cost which is beneficial for each party. Our solution makes it possible for service providers to outsource their access control procedures without requiring a trusted third party. The experiments confirm that our solution can provide a fast, comprehensive, and scalable access control mechanism.
