Private substitution (PS) is a problem for replacing one party’s binary string with the other party’s binary string in a privacy preserving manner. It is a new application of secure multi-party computation. In this paper, a protocol for PS using Pauli gates XZ and SWAP gate is put forward. A quantum secure direct communication protocol is also used to transmit some classic information. Correctness analysis shows that parties can get the correct substitution results. The security of the proposed protocol is also analyzed, which shows that the protocol can resist attacks from outside and participants. The quantum private substitution protocol can be used to solve quantum private set intersection problem and quantum private set union problem.

私人替代问题的量子协议

私有替换(PS)是一个以隐私保护方式将另一方的二进制字符串替换为另一方的二进制字符串的问题。它是安全的多方计算的新应用。本文提出了一种使用泡利门X,  Z和SWAP门的PS协议。量子安全直接通信协议也用于传输一些经典信息。正确性分析表明,各方可以得到正确的替代结果。对该协议的安全性也进行了分析,表明该协议可以抵御外界和参与者的攻击。量子私有替换协议可以用来解决量子私有集相交问题和量子私有集联合问题。
