基于椭圆曲线的可转移不可否认的数字签名方案

A Convertible Undeniable Signature Scheme Based on Elliptic Curve Cryptosystem

提出了一个新的可转移不可否认签名方案,它是将ElGamal签名方案和椭圆曲线密码体制有机的结合起来. 伪造签名的困难性等价于伪造ElGamal签名.新方案很容易转换成自验证签名.

A new convertible undeniable signature scheme is presented which combined ElGamal signature scheme with elliptic curve cryptosystem. Forging signature is equivalent to forging ElGamal signature. Its signature maybe converted into self-authentication signature very easily.
