本文结合基于身份数字签名能减少证书存储和管理开销的优点，利用椭圆曲线上的Weil 对构造了一个新的基于身份的代理签名方案。研究表明，新方案不仅具有良好的
安全性，而且具有较高的实现效率。
关键词：身份；代理签名；双线性对；椭圆曲线
Abstract: Proxy signature has quite an abroad application during our daily life. Combining with the profit of ID-based signatures with simplifying the certificates storage and manage spending, a efficient identity-based proxy signature is proposed by using the bilinear pairing defined on elliptic curves. We also make an brief analysis of its security and performance.
Keywords: Identity-based; Proxy signature; Bilinear map; Efficiency analysis
