摘　　要：提出了在多路径、多用户QKD网络环境中利用密钥位协商技术在任意两个QKD节点之间进行量子密钥协商的安全机制。采用基于密钥位协商的多路径量子密钥协商技术,入侵者如果要获取两个QKD节点之间的最终会话密钥,将不得不侵入网络中的所有中继设备并截获所有可能路径上的信息。分析结果表明,该方法使得网络中任意两个QKD节点之间的密钥协商安全性均得到较大提高。A secure mechanism of establishing aquantum key between any two end users on a multipath,multiuser network is proposed with the key bit-negotiation technique in an asynchronous QKD network environment.With an adoption of multi-path quantum key-negotiation technique based on the key bit-negotiation,an attacker have to intrude all the relays and possible path on the QKD network to get the final quantum key.The analysis result shows that this method makes much progress in the security of establishing aquantum key between any two nodes.
