Abstract

Abstract: A concept of non-disclosure contract signing protocol is given because those disadvantages of existed fair contract signing protocol.Based on the elements of designated-receiver signature scheme and giving an improved aggregate signature scheme，design a non-disclosure contract signing protocol.At last，an analysis of this protocol property is given.

Key words: bilinear pairings, fair exchange, contract signing protocol, non-disclosure

摘要： 针对目前已有的公平签约协议存在的不足，提出了签约协议非泄露性的概念，结合具有指定接受方签名方案的原理，改进双线性聚集签名方案，构建了一种具有非泄露性的公平签约协议，并对协议性质进行了分析。

关键词: 双线性对, 公平交换, 签约协议, 非泄露性
