摘要

字符串匹配是字符串操作的一个基本问题,而保持隐私的字符串匹配作为安全多方计算的一种特殊情况,在拍卖、竞价等商业领域有着广泛的应用。本文提出了一些解决这一私钥匹配问题的协议,分别分析了协议的安全性和正确性,并通过实验验证了协议的实际有效性。基于BMH算法,设计了一种更高效、更隐蔽私有信息的协议。

Privacy-Preserving Protocols for String Matching
String matching is a basic problem of string operation, and privacy-preserving string matching, as a special case of secure multi-party computation, has broad applications in auction, bidding and some other commercial areas. In this paper, some protocols are proposed to solve this private matching problem, the security and correctness are analyzed respectively, and the actual efficiency is tested by experiment. A protocol is also designed based on the BMH algorithm which is more efficient and conceals more private information.
