在半诚实第三方（TP）的帮助下，我们提出了一种新的量子私有比较协议，使两个参与者能够在不暴露各自私有输入的任何信息的情况下比较其私有输入的相等性。与以往的协议不同，我们的协议利用了三粒子W-Class状态和Bell状态之间的纠缠交换特性。该协议保证了协议的正确性、公平性和安全性。同时，所有的量子粒子都是单向传输，只要求包括TP在内的所有参与者都具有贝尔态测量和异或操作的能力，这使得我们的协议更加可行和高效。最后，详细分析了该协议对各种攻击的安全性。
We propose a new quantum private comparison protocol with the help of a semi-honest third party (TP), enabling two participants to compare the equality of their private inputs without exposing any information about their respective private inputs. Different from previous protocols, our protocol utilizes the properties of entanglement swapping between three-particle W-Class state and Bell state. The presented protocol can ensure correctness, fairness and security. Meanwhile, all the quantum particles undergo a one-way transmission, and all the participants including TP are just required having the ability to perform Bell-state measurement and exclusive-or operation which make our protocol more feasible and efficient. At last, the security of this protocol with respect to various kinds of attacks is analyzed in detail.
