Dynamic Access Control Scheme for IoT Devices using Blockchain
2018
Recently, Internet of Things (IoT) and block chain technology are growing rapidly. Particularly, there is an attempt to change the centralized access control method of IoT into a distributed method using a block chain. With the access control method currently presented, data communication between physically separated IoT devices is impossible. In addition, a policy corresponding to a number of dynamic IoT scenarios must be generated in advance in order for data exchanges to be performed. In this paper, we propose a dynamic access control scheme to solve the problems of the existing access control method for direct data communication between devices and to cope with the dynamic environment of IoT.
