Abstract:

The quantum secure communication technology provides theoretical absolute security and has great development prospects in the fields of power and finance. Therefore, based on the research status of quantum secure communication technology at home and abroad, this paper introduces the basic composition of quantum secure communication network, explains the working principle of quantum key distribution, and applies the quantum secure communication technology from two aspects: quantum logic architecture and quantum physics architecture. In this paper, the quantum secure communication technology is applied to the electricity payment system of electric power companies. The test results of the electricity fee payment system find that the data flow of the payment system is an ESP quantum key encrypted message, and the electricity fee inquiry and payment functions are all normal. At the same time, the key rate of the quantum key distribution device is high, which can fully support the key amount of the electricity fee payment system. The application of quantum secure communication technology in the electricity fee payment system provides theoretically unbreakable data protection, which fully guarantees the security of power financial information.

Key words: quantum secure communication, electricity bill payment, security
