论文摘要
量子私人比较（QPC）旨在完成不同用户的秘密的平等比较，而无需通过使用量子力学原理来披露其真实内容。在本文中，我们首先总结了当前QPC协议中存在的八种量子状态准备和传输模式。然后，通过使用分散的制备模式和单向收敛传输的模式，我们将构建一个新的多用户量子私人比较（MQPC）协议，该协议具有两个最大纠缠的两粒子，可以完成一个执行中的k用户之间任意对的k用户之间的平等比较。分析事实证明，其对外部攻击和参与者攻击都可以保证其输出正确性及其安全性。建议的MQPC协议可以使用当前技术实施。可以得出结论，量子状态的分散制备和单向收敛传输的模式有益于设计MQPC协议，该协议可以在一个执行中完成任意对对K用户之间的平等比较。
Quantum private comparison (QPC) aims to accomplish the equality comparison of the secrets from different users without disclosing their genuine contents by using the principles of quantum mechanics. In this paper, we summarize eight modes of quantum state preparation and transmission existing in current QPC protocols first. Then, by using the mode of scattered preparation and one-way convergent transmission, we construct a new multi-user quantum private comparison (MQPC) protocol with two-particle maximally entangled states, which can accomplish arbitrary pair's comparison of equality among K users within one execution. Analysis turns out that its output correctness and its security against both the outside attack and the participant attack are guaranteed. The proposed MQPC protocol can be implemented with current technologies. It can be concluded that the mode of scattered preparation and one-way convergent transmission of quantum states is beneficial to designing the MQPC protocol which can accomplish arbitrary pair's comparison of equality among K users within one execution.
