摘要

代理签名是指当某个签名者由于某种原因不能签名时

将签名权委托给他人替自己行使签名权的一种签名

代理签名在实际应用中有着重要的作用.提出了一个基于双线性配对的代理签名方案

并证明其在随机Oracle模型下是可证安全的.分析表明该方案比Zhang等的代理签名方案有更高的效率.

Abstract

A proxy signature scheme enables a proxy signer to sign messages on behalf of an original signer.Proxy signature schemes have been shown to be useful in many applications.A Proxy Signature Scheme from Bilinear Pairings is proposed.It is proved that the scheme is secure in the random oracle model and more efficient than Zhang's scheme.
