摘要
提出一个新的基于椭圆曲线离散对数问题的代理签名方案。新方案除满足代理签名的七条基本性质外,还对目前已有的代理签名方案中尚未很好解决的问题—代理权滥用进行了有效的控制。在新方案中,若代理签名人签名超过证书上规定的次数,则他的私钥就会被破解,从而真正做到了对签名代理权的控制。
Based on elliptic curve discrete logarithm problem A proxy signature scheme is proposed.This scheme not only satisfies seven fundamental properties of proxy signature, but also effectively controls the problem of delegation power misuse, which has not been satisfactorily solved at present. In this scheme, the proxy signer can sign a signature N times at most. If the proxy signer violates the condition, his private key will be revealed. So, this scheme can control the delegation power of the proxy signer.
