| 摘 要： | 在介绍椭圆曲线密码体制和代理签名基本概念的基础上。针对椭圆曲线离散对数问题的求解困难。提出了一个可以限制代理签名者的代理签名期限的代理签名方案。并讨论了这一方案的正确性和安全性。同时还介绍了本方案在嵌入式环境中的实现。

| Abstract: | First, proxy digital signature. the paper introduced the basic concept about the elliptic curve public key crypto system and Then, a new proxy digital signature scheme based on the elliptic curve is presented, which can set the time limit to the proxy signature. This scheme has been proved correct and secure is discussed. Moreover, the realization of this scheme in the embedded environment was also introduced. |
