摘要

不经意传输协议是安全多方计算中的基础协议

在保护用户隐私方面有着非常重要的应用.已有的不经意传输协议缺少统计分析能力.对此

引入多方安全求和及同态加密技术

并借助一种巧妙的编码方法

提出了一种具有统计特性的不经意传输协议.在保证协议原有正确性与安全性的基础上

增加了发送者的统计特性.即在一个执行周期后发送者能够统计出各个秘密消息发送出的总次数.理论分析表明该协议安全有效

在电子商务

医疗卫生等领域有着很好的应用前景.

Abstract

Oblivious Transfer (OT) protocol is a fundamental building block for Secure Multiparty Computation and finds critically important applications in protecting privacy in various settings.Nevertheless

existing OT protocols do not include the procedure to conduct the statistical analysis in a cooperative environment.Here

a new OT protocol is proposed with a cooperative statistical analysis by pursuing secure multiparty computation of the sum

adopting the homomorphic encryption scheme

and using a clever coding method.Specifically

the sender can calculate the total number of each message sent privately within a given period.Theoretical analysis indicates that the new protocol allows for secure and efficient transfer of private messages in an oblivious way and shows great promise for practical applications in Electronic Commerce

Healthcare Management and other secure systems as well.
