ENHANCE SECURED ACCESS POLICIES TO INTERNET OF THINGS RESOURCES USING THE BLOCKCHAIN ALGORITHM

Abstract

Internet of Things (IoT) is an emerging technology that has attracted considerable attention in recent years due to its wide range of applications. The development of IoT devices has brought new challenges to the field of security and privacy protection. This paper presents a novel approach to enhancing the access control mechanism for Internet of things, leveraging blockchain technology and inner product encryption to establish a robust and secure information service platform. The proposed approach is based on a blockchain-based access control scheme that combines blockchain technology with hashing to provide a greater level of threat mitigation via the suggested approach, all without the need for complex encryption. To validate the proposed solution, a practical test-bed comprising four prototypes of Network Operating Systems (NOSs) has been employed. Performance indices such as computing effort, storage overhead, and latency have undergone evaluation, affirming the viability and effectiveness of the designed solution.
