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.关键词
