摘　　要：提出了一个基于GHZ态的新颖且高效的量子秘密直接共享方案。在这个方案中,Alice通过让Bob和Charlie恢复Alice自己的操作来共享密钥,并利用三方之间GHZ态的相关性来检测窃听。分析表明,方案不仅可以抵抗外部窃听者的截获—重发攻击、纠缠附加粒子攻击,还能抵抗内部参与者的截获—重发攻击,效率达到了100%。This paper proposed a new and efficient scheme for quantum secret direct sharing based on GHZ state. In this scheme, Bob and Charlie were able to share Alice＇ s secrets by recovering Alice＇ s operation. It was used to detect eavesdropping between three parties by correlation of GHZ states. The scheme was secure against not only external eavesdropper＇ s intercept-and-resend and entangle-auxiliary attack, but also intercept-and-resend attack from internal participants. The total efficiency of the scheme approaches to 100%.
