摘　　要：针对代理签名在电子商务及电子政务中有很重要的应用背景,且一直是网络安全的难点这一情况,在一种基于身份的代理签名方案的基础上,分析利用了双线性对的良好特性,提出了一个新的身份基代理签名方案,并进行了安全性分析.分析结果证明,此方案很好地利用了身份信息,具有可区分性、可验证性、强不可伪造性、强可识别性、强不可否认性及抗滥用性,安全性很高,适合应用于电子商务、电子政务和电子货币等领域.Aiming at the difficulty in researching the scheme of proxy signature in E-business and electronic government affairs, based on an old ID-based scheme, a new identity based proxy signature is proposed employing the good characteristic of bilinear pairings. The security of the new scheme was analyzed. In the scheme, the identity message was imported into the signature key. The scheme possesses strong unforgeability, strong identifiability, strong undeniability, verifiability, distingguishability and avoids the misuse. It can be applied in the scene of E-business, electronic government affairs as well as net bank and large group.
