摘要
椭圆曲线代理签名是代理签名中的研究热点。它介绍了椭圆曲线代理签名体制的基本概念及相关知识,讨论了前向安全的研究动态。创新点是在针对目前椭圆曲线研究重点之一,椭圆曲线代理签名,给出了一种结合前向安全的椭圆曲线代理签名算法,该算法利用椭圆曲线代理签名的安全性和前向安全机制来保证了代理签名的安全性,并且在算法里实现了预防人为的私钥泄露。
The Elliptic curve proxy signature is the research hot of the proxy signature.This paper prestents the basic concept and related knowledge of elliptic curve proxy signature,discusses the present situation of the forward security. Its innovation point is that gives an Elliptic curve proxy signature combines the forward security algorithm to be aimed at the Elliptic curve proxy signature which is onet of the Elliptic curve’s keys, the algorithm uses the security of Elliptic curve proxy signature and the forward security to guarantee the security of the proxy signature and achieves preventing artificial private key leak.
