论文摘要
在本文中，提出了基于X型状态的Semiquantum Secret共享（SQSS）协议，该协议可以实现一个目标，只有当两个经典的交流者一起合作时，他们才能提取量子交流者的共享秘密密钥。详细的安全性分析事实证明，该协议对窃听者完全可靠。该协议具有一些优点：（1）仅需要一种量子纠缠状态作为初始量子资源； （2）它不使用量子纠缠交换或统一操作； （3）它不必事先在不同参与者之间共享私钥。
In this paper, a semiquantum secret sharing (SQSS) protocol based on x-type states is proposed, which can accomplish the goal that only when two classical communicants cooperate together can they extract the shared secret key of a quantum communicant. Detailed security analysis turns out that this protocol is completely robust against an eavesdropper. This protocol has some merits: (1) it only requires one kind of quantum entangled state as the initial quantum resource; (2) it doesn't employ quantum entanglement swapping or unitary operations; and (3) it needn't share private keys among different participants beforehand.
