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。
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.
