安全多方计算在解决销售量问题中的研究

Research on solving sales problem of secure multi-party computation

提出了一个销售量问题:不同的厂家有不同的商品,他们想知道相同商品在市场上的销售总量,但各自都不透露自己的私有数据。同时提出了一个解决销售量问题的协议,并且在半诚实模型下对协议的安全性和计算复杂度及通信复杂度进行了分析。

This paper introduces a sales problem：different manufacturers have different goods,and want to know the sales vol- ume of same goods in the market,but not reveal their own private datum.Meanwhile,the paper gives a protocol to solve the sales problem,and analyzes the security,computational complexity and communication complexity of the protocol in semi-honest model.
