论文摘要
在本文中，构建了一种新型的多方量子私人比较（MQPC）方案，用于与N级单粒子状态进行平等比较，并以圆形方式传输编码的粒子。在这里，n方采用Qudit转换操作来编码其私人秘密，并可以在一次性执行协议中比较其私人秘密的平等。提出的MQPC协议可以克服外部攻击和参与者攻击。特别是，其他各方和第三方（TP）可能不知道各方的秘密。
In this paper, a novel multi-party quantum private comparison (MQPC) protocol for equality comparison with n-level single-particle states is constructed, where the encoded particles are transmitted in a circular way. Here, n parties employ the qudit shifting operation to encode their private secrets and can compare the equality of their private secrets within one time execution of protocol. The proposed MQPC protocol can overcome both the outside attack and the participant attack. Specially, each party's secret can be kept unknown to other parties and the third party (TP).
