Abstract:

With the construction of the new power system, there are extensive interaction between source, grid, load, and storage, frequent interaction of various business data, and the integration of multiple communication methods into a network. The power system will face more network attacks, and the transmission of business data will face greater security risks. The quantum secure communication technology based on quantum mechanics principles, combined with Shannon’s one-time-pad theory, can achieve unconditional security in information theory, providing a feasible solution for improving communication security in power systems. This paper first analyzes the communication security improvement requirements for each link of “acquisition-transmission-storage-use” in the new power system. Then, it summarizes the technical principles, application situation, and domestic and foreign technological progress of quantum key distribution, quantum random numbers, and post quantum cryptography. Finally, it proposes follow-up technical research and application suggestions, aiming to improve the end-to-end security of power grid business data interaction, and help the power system to build information and communication infrastructure with anti-quantum computing capabilities.

Key words: new power system, quantum key distribution, quantum random number, post quantum cryptography
