A Blockchain Based Access Authentication Scheme of Energy Internet

Energy Internet provides important support to power transmission and substation distribution links, security is particularly significant. However, access authentication centralized to the certification center has brought great pressure on computing and communications. In this paper, a distributed authentication scheme for the energy Internet is proposed based on the blockchain technology, which is decentralized and undeniable. A PBFT consensus mechanism is implemented with the Shamir threshold secret sharing mechanism. Experiments show that the scheme can effectively improve the concurrent access efficiency of Energy Internet terminals.
