Research on Information Security Protection Technology of Client Side System

In order to improve the security protection of the customer-side energy use control system for data collection and monitoring, demand response, and energy efficiency improvement, it is urgent to further develop and improve the research on the security of customer-side system information collection and transmission encryption technology. By analyzing the characteristics of client-side system information collection and transmission, based on the synunetrical mixed 128-bit key AES-DES algorithm, the client-side system data trusted encryption transmission technology is studied, and the data trusted encrypted transmission model is established. And use the calculation example to simulate, compare the performance of the traditional AES algorithm and the enhanced AES algorithm. Because the enhanced version has better chaos, it can effectively deal with the complexity of the data in the process of client-side system acquisition and transmission and improve the ability to resist attacks.
