摘要

本文对一种自证明签名方案实施了伪造攻击.在这种攻击下CA通过改变数字签名中的相关参数

可以对其用户的任意消息伪造自证明签名.本文提出了能抵抗该攻击的改进方案

分析表明改进方案和Schnorr签名具有相同的安全性.

Abstract

A forgery attack is presented on the self-certified signature scheme.The results show that CA can forge a valid self-certified signature of his client on an arbitrary message by tampering with some parameters of the signature.An improved scheme is proposed to resist this kind of forgery attack.Analyses show that the improved scheme has the same security features with Schnorr signature.
