摘　　要：量子密钥分发(Quantum Key Distribution,QKD)与一次一密加密机制的结合,可以为远程通信方提供信息安全的保密通信服务。由于QKD设备固有的点对点特性研究和发展QKD设备组网技术是为更大范围、更大规模的用户群体提供保密通信服务的必须途径。针对QKD网络的仿真需求本文设计了一种基于两层架构的QKD网络仿真系统,并利用NS3平台进行了实现。实验结果及性能分析,验证了仿真系统的可行性,该系统能够为QKD网络的高效构建提供有力的支撑和保障。Quantum Key Distribution(QKD),combined with the encryption mechanism of one-time-pad,can provide information-theoretical secure communication service for remote communication parties.Due to the inherent point-to-point characteristics of QKD device,the research and development of QKD network technology is critical for providing secure communication services for large-scale of users over a large area.Aiming at the QKD network simulation requirements,a QKD network simulation system based on two-layer architecture is designed in this paper,with the implementation on NS3 platform.Experimental results and performance analysis validate the feasibility of the proposed simulation system,which can provide strong support and guarantee for the efficient construction of QKD network.
