论文摘要
本文提出了两种容错身份验证的量子对话（AQD）方案，该协议分别使用逻辑铃状状态作为量子资源，它们分别打击了集体淘汰噪声和集体旋转噪声。每个提出的协议每个都可以在一种集体噪声通道上同时且牢固地牢固地完成两个参与者之间的相互身份身份验证和对话。在提出的协议中的每一个中，假定通过经典通道传输的信息被认为是可窃听且可修改的。选择样本逻辑量子位的测量基础的关键是在两个参与者之间私下预共享。采用了贝尔状态测量而不是四个QUIT的关节测量值进行解码。两位参与者通过诉诸辅助逻辑铃的直接传输，共享消息逻辑钟状状态的初始状态，以避免信息泄漏问题。可以检测到的模仿攻击，中间攻击，修改攻击和特洛伊木马的攻击。
Two fault tolerant authenticated quantum dialogue (AQD) protocols are proposed in this paper by employing logical Bell states as the quantum resource, which combat the collective-dephasing noise and the collective-rotation noise, respectively. The two proposed protocols each can accomplish the mutual identity authentication and the dialogue between two participants simultaneously and securely over one kind of collective noise channels. In each of two proposed protocols, the information transmitted through the classical channel is assumed to be eavesdroppable and modifiable. The key for choosing the measurement bases of sample logical qubits is pre-shared privately between two participants. The Bell state measurements rather than the four-qubit joint measurements are adopted for decoding. The two participants share the initial states of message logical Bell states with resort to the direct transmission of auxiliary logical Bell states so that the information leakage problem is avoided. The impersonation attack, the man-in-the-middle attack, the modification attack and the Trojan horse attacks from Eve all are detectable.
