AI Technical Summary
In the existing power system edge computing environment, the reliability and security of the access authentication process are poor, which affects the safe and stable operation of the system.
Elliptic curve cryptography is used to generate keys, and pseudo-identities are generated through edge node devices and terminal devices. Authentication is performed using the system signature master key and the information encryption master key, realizing two-way identity authentication between edge node devices and the cloud center, as well as authentication between edge node devices. A trust list is established to complete the access authentication for edge computing in digital substations.
It improves the reliability and security of access authentication in the edge computing environment of power systems, solves the problems of key management and distribution difficulties, realizes anonymous, fast and simple user identity authentication, and protects user privacy.
