In recent years, the global data network is developing at an astonishing speed, providing efficient tools and convenient platforms for information exchange and economic development. With the rapid development of electric power construction, the electric power automation data network is also rapidly expanding, and it is moving towards covering all electric power enterprises in an all-round way. The digitalization of electric power system is the general trend. Power dispatching automation system, power distribution automation system, electricity billing system, power market technical support system and transaction system, power customer service center system, substation automation system, power plant monitoring system, MIS system, etc., all of which rely on high-speed data Transmission and exchange are built as basic means. The power automation data communication network uses tools and platforms such as the Internet and wireless networks to improve the convenience of data transmission and reduce the workload of development and maintenance. At the same time, it also brings new problems. This is the efficiency of data transmission. Leakage on the Internet, and damage by attacks, etc.

The current power automation system mainly adopts the combination of wired communication and wireless communication. Among them, the wireless communication method can not only overcome the inherent deficiency of the physical environment limitation of the wired network, enhance the adaptability of the system to the environment, but also provide good mobility and configurability. However, compared with the wired communication method, the data transmission efficiency of the wireless communication method is relatively low, and the effectiveness of information is easily affected, and because the communication channel is open, it is impossible to prevent attackers from eavesdropping, maliciously modifying and forwarding, and the information security problem of wireless communication is even more serious. for highlighting.

For the data interaction problem in the wireless communication mode of the power automation system, it is essential to carry out comprehensive, reliable, safe and multi-level backup of the data system first. In addition, various security products, no matter firewall, anti-virus, anti-virus Hackers, anti-intrusion, etc., are more or less responsible for protecting data, but overall they only play a role in physical protection of the data system from the data source, while seriously ignoring the protection of data transmission and false data requests . Although some data are encrypted and then transmitted, most of them only use a simple encryption mechanism. Moreover, once the keys of the communication parties are generated, they are often used for a long time, failing to achieve one-time encryption. In addition to the weak encryption mechanism and improper key management, it is easy to cause data to be cracked, and there are serious hidden dangers of data information security. When the amount of data transmission increases, it is easy to cause data congestion, seriously reduce the effectiveness of data, and affect Safe and stable operation of the power grid.
