摘要: 为使量子秘密共享易于实现,提出了一种基于Bell态纠缠交换的协议. 参与方的量子信道构成一个环,通过在环上添加或删除节点可以构造任意多方协议,并且对其他参与方没有任何影响. 分析表明,上述协议不仅能抵抗外部窃听者的窃听,而且能抵抗内部参与方的欺骗,具有无条件安全性.

Abstract: To simplify the implementation of quantum secret sharing, a protocol based on Bell states entanglement swapping was proposed. The quantum channels among all players constituted a ring. Through adding or deleting nodes in the ring, protocols for any number of players could be designed. Investigation shows that the protocol is secure against the eavesdropping not only by eavesdroppers but also by the players.
