The method can calculate the quantum key update frequency and distribution strategy of each power business by itself. The system performs the key self-evolution of the synchronization between the sender and the receiver by transmitting the random quantity of short length generated in the communication in the quantum channel. It replaces the traditional update method where a new full key must be sent and received after each update must be renegotiated. Finally, this paper proposes the key reading mode between the service terminal and the quantum key mobile storage device, the interface protocol between the service terminal device and the quantum key mobile storage device, and the key management method suitable for the power distribution service terminal.

This paper proposes an information encryption transmission method for power system communication network based on quantum security communication technology, which can effectively encrypt the information in power system and ensure the security of information transmission. Based on quantum secure communication technology, the communication network architecture of power system is constructed. Quantum-layer quantum key distribution Network (QKD) uses BB84 protocol to realize quantum information exchange and optical synchronization, provide quantum key to control layer, and encrypt network information of power system. The control layer is responsible for monitoring QKD status, reasonably managing keys, and issuing communication commands to the communication layer. The communication layer switch encrypts and transmits the power system communication network data generated by the application layer through the minimum attenuation routing algorithm according to the controller instruction. Experiments show that this method can realize the information encryption of power system communication network, and the quantum key encryption function, key source exchange function and the number of encryption services meet the requirements. The application of this method can improve the throughput and communication connectivity of power system communication network.
