Research on Cybersecurity in Power Systems.

The power system network is gradually developing to the Internet open mode. The informatization of industry and infrastructure has expanded the occurrence scope and transmission path of the traditional internal power system network risks. Its openness has brought more network security problems, and the convenience and security risks of the power system coexist. As an important part of key infrastructure, the electric power industry not only involves people's daily life, but also has a profound impact on the field of industrial control, and even on national security. We present the current investigation and analysis of the power system network security situation, including the current power grid attack means, classify and summarize the power grid network security risks, and elaborate on the traditional power system network security architecture. At present, the common network security protection technology of the power system includes encryption and digital signature technology, XML security technology, VPN technology applied in the power system, intrusion detection system, etc. We introduce a series of power grid network security solutions and measures in detail, including the research progress of power grid security at home and abroad. It is particularly important to strengthen the safe construction of power grid facilities and the safety protection of electric power enterprises. Opportunities and challenges coexist, the power industry should improve the awareness of network security, establish a security management platform, strengthen the security technical support, and take measures to prevent security risks.
