摘　　要：多方量子密钥分发使用分布式量子组密钥协商实现组会话密钥分发。文章所提协议将多粒子GHZ态作为量子资源,采用分布式思想,利用纠缠和泡利运算实现多方会话密钥分发。其中,群会话密钥由所有群成员共同决定,避免了单个节点导致的不可信问题。该协议减少了密钥协商次数,加快了群会话密钥的生成,具有可行的量子比特效率。Multi-party quantum key distribution uses distributed quantum group key negotiation to achieve group session key distribution.The protocol proposed in the article uses multi-particle GHZ states as quantum resources,adopts distributed thinking,and utilizes entanglement and Pauli operations to achieve multi-party session key distribution.Among them,the group session key is jointly determined by all group members,avoiding the problem of unreliability caused by a single node.This protocol reduces the number of key negotiations,accelerates the generation of group session keys,and has feasible quantum bit efficiency.
