摘　　要：为了更好地在QKD(Quantum Key Distribution)中服务多用户组播通信,在量子密钥成对产生的特殊应用背景基础上,构建了组密钥协商模型,提出了一种基于分簇结构和二进制编码的组密钥协商方案.该方案消耗少量的端端量子密钥,经过安全协商,得到一致的组密钥.当新成员加入或者旧成员离开时,密钥更新快速易行.分析发现,该方案具有较好的安全性.In QKD（quantum key distribution） networks, in order to serve the multicast communications a- mong multiple users better, based on the special application background of quantum key generation in pairs, a group key agreement model was built and a group key agreement scheme based on clustering structure and binary code was presented. This scheme consumes a small amount of end-to-end quantum keys, and then obtains a consistent set of keys via security consultation. When new members join or old members leave, the key update is fast and easy. Analysis shows that the scheme has good security.
