Design of cross-system identity authentication system suitable for new-type electric power system

In order to solve the flexibility boundary security access problem of new-type electric power system, this paper has designed a cross-system identity authentication system which can help power grid and systems both on the generation side and demand side to build a foundation of trust for further data sharing. This system can realize a variety of cryptograph-based unified identity authentication such as PKI-based, IBC-based, blockchain-based identity authentication, etc. This system is also designed to meet high concurrency requirements of identity authentication. In order to verify the fucntion of the CSIA system, this paper has also make the system workflow simulated. The test results showed that the system can provide a cross-system identity authentication service effectively for systems and devices based on different identity authentication technology.
