摘要：

现有的代理数字签名方案大多是基于离散对数问题和大数因子分解问题的方案。本文将代理签名的思想用于椭圆曲线数字签名，提出了基于椭圆曲线的代理签名方案，除了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——代理权的滥用进行了有效的控制。在本方案中，签名人不能生成代理签名，也不能给多于一个的人以代理权，真正做到了对签名代理权的控制。本方案基于椭圆曲线，且整个过程参与方少，具有安全性高、密钥量小、便于实现等优点。

Abstract:

Up to now most of the known proxy digital signature schemes are based on discrete logarithmic problems or big number factorization problems. In this paper, I applied the idea of proxy digital signature scheme to elliptic curve digital signature algorithms by presenting a new proxy digital signature scheme based on elliptic curve discrete algorithmic problems. This scheme has not only satisfied the seven fundamental properties, but also has a special benefit, that is the signature can not produce a proxy signature, and also can not give the right of proxy to another one, which is a completely control of the right of proxy. The scheme is based on elliptic curve discrete logarithmic problems,with the merits of high security,small private key and easy to carry out.

Key words: elliptic curve discrete logarithmic problems, digital signature, proxy signature
