| Abstract |
Communication technology is increasingly evolving, and the new generation of 5G is characterized by three main features: high capacity, high speed, and low latency. With the vigorous promotion and application of 5G communication technology in industrial automation, smart city, smart grid, healthcare and other fields, the security transmission problem of 5G network continues to receive widespread attention, how to utilize powerful encrypted communication algorithms to ensure the secure transmission of heterogeneous information data between massive devices is an urgent problem to be solved nowadays. Based on the basic principle of quantum key distribution, this paper proposes a quasi-real-time virtual key pool construction strategy, which improves the whole process of encryption service bearing through the quasi-real-time virtual key pool, and ensures the secure transmission of horizontal and vertical quantum keys of the distribution terminal. © 2023 IEEE. |
