Research on distributed authentication of power IoT based on Hyperledger blockchain

With the development of energy Internet and the implementation of "cloud, big, material and mobile" strategy, the traditional centralized access authentication mode of power Internet of Things terminal is difficult to meet the ubiquitous application needs. Based on the super-ledger technology of alliance blockchain, this paper studies the distributed access authentication technology of power Internet of Things terminal, combines the key sharing and distribution protocol in secure multi-party computing with the super-ledger consensus algorithm, and proposes an effective access authentication scheme for power Internet of Things terminal. The simulation results show that the proposed scheme has advantages in authentication time and resource consumption.
