Authentication and Encryption System for User Information Security in Power Grid System

The power-related information used in the power consumption information collection system is an important secret of a country’s power industry, and its illegal use and loss may bring unthinkable consequences. The purpose of this paper is to study the user-oriented information encryption and encryption system in the power grid system. This article first analyzes the problems that may exist in the power grid system in detail, and mainly evaluates the safety level of the system in the store from the aspect of the system master station risk. Then studied the authentication encryption module. The experimental part designs an authentication key agreement protocol based on the State Grid certificate. By analyzing the performance of EAP-TLS, WAPI and the protocol designed in this paper, the communication times of the three protocols are 9, 6 and 3 respectively. It can be seen that the encryption protocol designed in this paper has better performance than other protocols. Aiming at the problems of the power grid system, in order to improve the security of the power grid system, this article also puts forward related suggestions.
