摘　　要：随着量子信息技术的发展,量子密钥分发网络逐步应用到现实生活中。为了提高量子密钥分发网络的安全性,文章对比分析了随机路由和多路径路由方案,并提出一种最少公共节点的多路径路由方案。该方案适用于链路分布较密的网络结构,通过找到多条互不相交的多路径,减少冗余路径,提高密钥路由的安全性,减少路由过程中量子密钥的消耗。最后文章通过实例对该路由方案进行了分析验证。With the development of quantum information technology,quantum key distribution network is gradually applied to real life.In order to improve the security of quantum key distribution network,this paper compares and analyzes the random routing and multi-path routing schemes,and proposes a multi-path scheme with the least common nodes.This scheme is suitable for network structures with densely distributed links.By finding multiple disjoint paths,the scheme reduces redundant paths,improves the security of key routing,and reduces the consumption of quantum key in the routing process.Finally,an example is given to verify the routing scheme.
