A large amount of data information will be generated during the construction and operation of the power system, and once these data are leaked, it will undoubtedly threaten the information security of power users, which will bring avoidable economic losses to power companies and users. Therefore, many electric power companies are paying more and more attention to data security, and data encryption technology solves this problem well. And this article has launched a detailed analysis on the application of data encryption technology in the construction of electric power information. At the same time, it has carried out an in-depth discussion with the practical application of the two-layer encryption method in the informationization of electric power enterprises. I hope the research results of this article It can provide a certain reference for the information security management of the power system.

In order to meet the system needs of miniaturization, real-time, high-speed data and high reliability transmission in remote sensing camera, a high-speed serial protocol based on high-speed serial/parallel converter SerDes is proposed. For the SerDes high-speed serial data transmission chip for the physical layer, FPGA for the link layer of the communication system, design high-speed serial transmission communication protocol. Through the development of a simplified protocol for the upper user to provide a simple data interface. The system completed the data rate of 12.5Gbps point to point high-speed transmission. Verification is done by sending a pseudo-random code between boards. System work 3 hours, the measured bit error rate is less than 10-12.
