Design of Multi-dimensional Electronic Channel Unified Identity Authentication Method for Power Information System

At present, State Grid Corporation has established a wealth of electronic service channels, including 95598 website, electric E-power, hand-held power, national network mall, E-charging, WeChat, with the rich application of various electronic channels, while gradually facilitating user use. There has been a problem of poor user experience such as registration and query service sharing, lack of unified management of multiple electronic service channels, and lack of service supervision for various electronic channels. Therefore, it is urgent to start from the source to conduct specific research on unified identity authentication system among various electronic channels. So in this paper, we proposed a multi-dimensional electronic channel unified authentication method based PKI certificate for power information system. By the proposed method, users can directly access each application system and perform fast and secure switching between application systems without multiple authentication process, providing users with the convenience and security of engaging in complex business management activities.
