【摘要】 在研究基本代理签名方案以及分析现阶段多种代理签名方案的安全性优缺点的基础上,提出了一个基于椭圆曲线离散对数问题(Elliptic Curve Discrete Logarithm Problem,ECDLP)的改进代理签名方案,该方案具有算法速度快、网络传输量小、占用资源少以及灵活性好等特点.更多还原

【Abstract】 Basic proxy signature scheme was presented,and the security advantages & flaws of some typical proxy signature schemes were analyzed in the paper.Base on the elliptic curve discrete logarithm problem(ECDLP),an improved signature scheme was proposed with faster computing speed,few network transfer amount,little resource occupying,and better flexibilities.更多还原
