A Blockchain Based Terminal Security of IoT

With the rapid development of the IoTs, the distributed access of a large number of terminals poses a serious challenge to the credibility of the system. To solve the above problems, based on the decentralized block chain technology, a terminal authentication scheme suitable for the IoT is proposed. The scheme uses block chain node to record information of terminals, the consensus mechanism is improved through key sharing algorithm, and efficient distributed authentication is realized. The simulation results show that the proposed scheme is feasible.
