Abstract: Quantum key distribution-based quantum secure communication (QSC) technology is one of the effective solutions to improve the level of information security protection. In recent years, related technology research, equipment development and demonstration applications have developed rapidly, but the standards for testing and evaluation of QSC system has not been completely established. On the basis of reviewing the progress of quantum secure communication technology and its application, the paper introduces the construction of electric power QSC demonstration network and the application of related equipment, and proposes a comprehensive evaluation scheme from different aspects such as quantum key distribution, management and application. The feasibility and technical effects of applying QSC technology in power communication networks are verified in the actual network environment. In the end, the prospect of QSC applications is given.

Key words: quantum key distribution, quantum key management, quantum secure communication, electric power communication, test and evaluation
