As the next-generation communication system, quantum security has to satisfy the security requirements. Also, it is especially important to build the fusion application of energy network quantum private communication technology and conventional network, and to form a safe and reliable quantum-level communication technology solution suitable for the power grid. In this paper, from the perspective of the multi-terminal quantum key application, combined with a mature electricity consumption information collection system, a handheld meter reading solution based on quantum private communication technology is proposed to effectively integrate the two and achieve technological upgrading. First, from the technical theory and application fields, the current situation of quantum private communication technology and its feasibility of combining with classical facilities are introduced and analyzed. Then, the hardware security module and handheld meter reading terminal equipment are taken as typical examples to design and realize quantum key shared storage, business security process application model; finally, based on the overall environment of quantum key distribution, the architecture design of multi-terminal quantum key application verification is implemented to verify the quantum key business application process.

Thirdly, this paper uses the local search algorithm to optimize the parameters of the MDI-QKD protocol under symmetric and asymmetric conditions, and gives its optimized key rate. Finally, this paper uses the actual quantum key distribution equipment, quantum VPN and network tester to build an experimental environment. The system uses a comprehensive network tester to simulate the power grid application business information to test and statistically analyze the core performance characteristics of quantum VPN, such as throughput, delay, and encryption algorithm. The experimental results can provide a reference for the popularization and application of the quantum secure communication system in the power grid production control and management information business.

Meanwhile, the quantum security communication technology, which is absolutely safe in in theory, can cope with the challenges brought by the improvement of computing. Basing on quantum security communication technology, this paper proposes a general architecture of quantum security communication system in power grid. Problems existing in the application of quantum secure communication technology in power system and key technologies that required to be developed are analyzed concretely. Eventually, several typical energy Internet functions, such as major power-securing events and Unified meter reading and charging service (UMRCS) are proposed to verify the rationality and feasibility.

Research on Key Technologies of Quantum Key Distribution in 5G Power Private Network Communication Under Smart Grid

Yun Ren, Lei An, Gang Yang +5 more

This paper proposes a distribution network application scheme based on quantum secure communication and 5G hard slicing private network. 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. The experimental results show that the described method can realize the automation and intelligence of the optimal distribution of quantum keys for accurate data protection of various power services. This method can construct a precise and secure data protection mechanism based on quantum keys.
