论文摘要
通过使用D级单粒子状态，第一个多方Semiquantum私人比较（MSQPC）协议可以在一个协议执行中判断来自两个以上的两个经典用户的私人输入的大小关系。该协议需要一个量子第三方（TP）和一个经典的TP的帮助，他们俩都可以独自表现出来，但不能与其他任何人合谋。对于实施此协议，量子纠缠交换和统一操作既不是必需的。仅需要进行TPS进行D维单粒子测量。正确性分析验证了比较结果的准确性。安全分析验证了外部攻击和参与者攻击都可以抵抗。
By using d-level single-particle states, the first multi-party semiquantum private comparison (MSQPC) protocol which can judge the size relationship of private inputs from more than two classical users within one execution of protocol is put forward. This protocol requires the help of one quantum third party (TP) and one classical TP, both of whom are allowed to misbehave on their own but cannot conspire with anyone else. Neither quantum entanglement swapping nor unitary operations are necessary for implementing this protocol. TPs are only required to perform d-dimensional single-particle measurements. The correctness analysis validates the accuracy of the compared results. The security analysis verifies that both the outside attacks and the participant attacks can be resisted.
