论文摘要
在本文中，我们提出了一种基于D级单粒子状态的大小关系的新型私有比较（SQPC）方案。该设计的协议可以在半honest第三方（TP）的帮助下比较来自两个古典用户的不同隐私消息的大小关系，后者被允许独自表现不佳，但不能与其他任何人勾结。正确的分析表明，该协议可以获得正确的比较结果。安全分析事实证明，该协议可以抵抗著名的外部攻击和参与者攻击。此外，该协议可以保证TP不知道准确的比较结果。与唯一现有的SQPC尺寸关系协议（量子信息过程。20：124（2021））相比，该协议在初始量子资源，TP的测量操作以及TP的知识方面利用了它。
In this paper, we propose a novel semiquantum private comparison (SQPC) protocol of size relationship based on d-level single-particle states. The designed protocol can compare the size relationship of different privacy messages from two classical users with the help of a semi-honest third party (TP), who is permitted to misbehave on her own but cannot be in collusion with anyone else. The correctness analysis shows that this protocol can gain correct comparison results. The security analysis turns out that this protocol can resist famous outside attacks and participant attacks. Moreover, this protocol can guarantee that TP does not know the accurate comparison results. Compared with the only existing SQPC protocol of size relationship (Quantum Inf. Process. 20:124 (2021)), this protocol takes advantage over it on the aspects of initial quantum resource, TP's measurement operations and TP's knowledge about the comparison results.
