摘要： 设计了基于多用户的量子密钥共享协议，该协议在多个用户组成的3个簇中共享多串光子和多个GHZ态。在S簇中，S1, S2, …, Sn-1利用多串光子直接编码，生成包含mN元的量子态，传输给Sn。Sn通过M簇中任选的一个用户Mj，传递给D簇中每一个用户D1, D2,…, Dn。该协议利用现有的手段可以实现。

Abstract: The paper designs a mutual quantum secure direct communication scheme, which shared a sequence of single photons and greenberger-horne-zeilinger (GHZ states) in the quantum networks. S1, S2, …, Sn-1 members in cluster S directly encode their respective keys on the states of single photons; then generalizes this situation transmit to the last one of the cluster. Sn encodes the secret message directly on a sequence of particle states and transmits them to D1, D2,…, Dn supervised via one of the cluster M. It proves that it is unconditionally secure.
