Dynamic Access Control Scheme for IoT Devices using Blockchain
DongYeop Hwang, Jungyong Choi, Ki‐Hyung Kim · 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.
