摘要

提出了一个新的基于椭圆曲线的可转换的指定证实人签名方案.该方案不仅能抵抗一切伪造攻击

而且具有可转换和可收回的特性.可转换特性就是在需要的时候可以将指定证实人签名变为普通数字签名

任何人都可以验证它的有效性.可收回特性是指签名者根据需要可以收回委托给指定证实人的签名验证权.新方案是基于椭圆曲线构造的

所以具有安全性高

速度快

密钥最小

简单等优点.

Abstract

A new convertible designated confirmer signature based on elliptic curve is presented.The new scheme not only can resist all forgery attacks

but also has the properties of convertibility and retraction.The convertibility is that the designated confirmer signature can be converted into general signature if needed.The retraction is that the original signer can retract the right of the designated confirmer's signature verification if needed.The new scheme is constructed based on elliptic curve

therefore the scheme is possessed of the merits of higher security

higher efficiency

smaller key

and very simplicity etc.
