摘要

本文利用d维单粒子态,在两个半诚实量子第三方(TP)的协助下,同时实现了三个半量子密码学协议,即多方半量子私密比较(MSQPC)协议、多方半量子乘法(MSQM)协议和多方半量子求和(MSQS)协议。在这里,所提出的 MSQPC 方案是唯一一个专门用于判断来自两个以上半量子参与者的秘密整数的大小关系而无需预共享密钥的协议。而所提出的 MSQM 协议首次将半量子性的创新概念吸收到量子乘法中,可以计算来自两个以上半量子用户的私有输入的模乘。至于所提出的 MSQS 协议,它是唯一一个旨在完成三个以上半量子用户私有整数的模数相加的半量子相加协议。在这三个拟议的协议中,量子纠缠交换和单元操作都是不必要的。安全分析详细验证了三个拟议协议都能抵御外部攻击和内部攻击。

Hybrid protocols for multi-party semiquantum private comparison, multiplication and summation without a pre-shared key based on d-dimensional single-particle states

In this paper, by utilizing d-dimensional single-particle states, three semiquantum cryptography protocols, i.e., the multi-party semiquantum private comparison (MSQPC) protocol, the multi-party semiquantum multiplication (MSQM) protocol and the multi-party semiquantum summation (MSQS) protocol, can be achieved simultaneously under the assistance of two semi-honest quantum third parties (TPs). Here, the proposed MSQPC scheme is the only protocol which is devoted to judging the size relationship of secret integers from more than two semiquantum participants without a pre-shared key. And the proposed MSQM protocol absorbs the innovative concept of semiquantumness into quantum multiplication for the first time, which can calculate the modulo d multiplication of private inputs from more than two semiquantum users. As for the proposed MSQS protocol, it is the only semiquantum summation protocol which aims to accomplish the modulo d addition of more than three semiquantum users’ private integers. Neither quantum entanglement swapping nor unitary operations are necessary in the three proposed protocols. The security analysis verifies in detail that both the external attacks and the internal attacks can be resisted in the three proposed protocols.
