| 摘 要： | 提出一种基于云服务器外包的安全两方集合计算协议，采用多项式的点值计算和Boneh加密体制相结合的思想，解决两方集合交集问题，并且实现了对用户私有集合的隐私保护.协议执行过程中各参与者的计算完全独立，没有任何数据的交互形式.协议允许参与者独立将各自的私有数据存储到云服务器，因此不需要多次上传副本.证明了协议的正确性和安全性，并对协议性能进行了分析.分析结果表明，新协议具有较低的计算成本. |
| 关 键 词： | 安全多方计算 隐私集合交集 云外包 |

| Abstract: | A secure two-party set computation protocol based on cloud server outsourcing was proposed. The protocol solved the problem of the intersection of two sets and realizes the privacy protection of privacy sets of participants with the combination of the point value calculations of polynomial and Boneh encryption system. During protocol execution, the calculation of each participant was completely independent without any form of data interaction. It allows multiple participants to storage their private data to the cloud server independently without having to upload copies multiple times. The correctness, security and performance of protocol was proved, and the result of experimental analysis show that the calculation cost of the protocol is lower. |
