Abstract:

Quantum key distribution (QKD) based quantum secure communication can withstand the security challenges brought by quantum computing and has now entered the stage of industrial-scale application.However, due to the limitations of the QKD network architecture and service capabilities, the current system cannot meet the development requirements of future quantum secure communication in business diversification, user scale, ubiquitous applications and so on.To address this issue, a quantum secure communication application service system architecture model and mechanism was proposed, which implemented unified management of quantum keys and supported various types of user devices and applications to obtain quantum keys in various ways flexibly and securely.This system decoupled the QKD network from the upper-layer applications by introducing a quantum security service layer and coordinated the development of the QKD network and the development of secure communication services effectively, which was conducive to promoting the large-scale application of quantum secure communication.

Key words: quantum communication, quantum secure communication, quantum key distribution, key management
