摘　　要：基于信任中继的量子密钥分发(QKD)网络由于扩展性强(?)技术容易实现成为目前保密通信组网的首选方案,路由选择问题是信任中继QKD网络应用于实际要解决的一个重要方面￡文章首先提出信任中继QKD的组网结构和链路费用参量:其次建立了保证业务QoS和网络资源合理分配的路由选择数学模型;最后针对语音通信,提出一种池内密钥转化为速率的方式并仿真分析了QKD网络路由选择的效果￡仿真结果表明信任中继QKD网络路由选择的成功率较高,网络密钥的资源分配情况也较好,信任中继QKD网络用来进行保密通信是有效可行(?)Because of its good expandability and technology easy to implement, the trust relay Quantum Key Distribution（QKD） network becomes the preferred secure communication net-work scheme at present. The routing problem need to be solved if the network is actually applied. The network structure and link cost metric parameters of the QKD network were introduced firstly. The routing mathematical model was then established maintaining QoS and resource distribution well. Finally, for the speech communication, a scheme of the key in the pool change to the rate was proposed and the network routing effect was simulated. The simulation results illustrate that the trust relay QKD network routing success rate is higher and the key resources allocation is sound. The trust relay QKD network used for secure communication is effective and reliable.
