论文摘要
为了避免在两个授权参与者（即爱丽丝和鲍勃）之间进行信息泄漏的风险，即基于任何两个钟声之间的纠缠交换和共享的秘密贝尔国家，提出了量子对话协议。所提出的协议将使用钟状态作为信息载体组合在一起的块传输，两步传输和统一操作的想法。除了任何两个钟声之间的纠缠交换之外，还使用共享的秘密钟状状态来克服信息泄漏问题，这不仅使鲍勃意识到准备的初始状态，而且还用于鲍勃的编码和纠缠交换。安全性分析表明，所提出的协议可以抵抗外部窃听前夕的一般主动攻击。此外，夏娃的最大信息量之间的关系可以增加并得出检测概率。
In order to avoid the risk of information leakage during the information mutual transmission between two authorized participants, i.e., Alice and Bob, a quantum dialogue protocol based on the entanglement swapping between any two Bell states and the shared secret Bell state is proposed. The proposed protocol integrates the ideas of block transmission, two-step transmission and unitary operation encoding together using the Bell states as the information carriers. Besides the entanglement swapping between any two Bell states, a shared secret Bell state is also used to overcome the information leakage problem, which not only makes Bob aware of the prepared initial state but also is used for Bob's encoding and entanglement swapping. Security analysis shows that the proposed protocol can resist the general active attacks from an outside eavesdropper Eve. Moreover, the relation between the maximal amount of information Eve can gain and the detection probability is derived.
