摘要

针对在线/离线签名用于待签署的信息一旦被确定

就必须用极少的时间生成签名的情况

构造了两种基于双线性对的在线/离线签名方案.在标准模型下

新方案被证明是安全的.并且

在不提高总体计算量的前提下

新方案的在线阶段计算量是文献改进前方案计算量的1/4. 更多还原

Abstract

Online/Offline signatures are used in a particular scenario where the signer must respond quickly once the message to be signed is presented.This paper presents two online/offline signature schemes from bilinear pairings.Without the random oracle assumption

these two schemes are proved secure.Furthermore

without increasing the overall computation

the new schemes’ online computation requires only about one fourth of that of the old schemes
