摘　　要：基于信任中继的量子密钥分发(QKD)网络由于其组网效果好、扩展性强、技术容易实现成为未来保密通信组网的首选方案。文章首先介绍QKD网络的分类和现状;然后提出信任中继网络的基本网络拓扑模型,在此基础上分析了网络的信道和密钥中继方式;最后提出了影响信任中继网络组网效果和性能的决定性参量,分析比较了信任中继网络采用不同选路方式的优缺点。Because of its good network effect, expandability, and easy implementation, the trust relay Quantum Key Distribution（QKD）network becomes future secure communication net- work preferred scheme. The classification and current status of the QKD network were introduced firstly; then the basic network topology model of the trust relay network, network channel and key relay mode were presented. Finally, the decisive parameters which affect the effectiveness and performance of the trust relay QKD network were proposed. The advantages and disadvantages of the trust relay network using different routing methods were compared and analyzed.
