结合前向安全的椭圆曲线代理签名

An Elliptic curve proxy signature combines the forward security

椭圆曲线代理签名是代理签名中的研究热点。通过对椭圆曲线代理签名体制及前向安全技术进行了研究,提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代理签名的安全性,并且还可预防人为私钥泄露对系统安全造成的威胁。

The Elliptic curve proxy signature is the research hot of the proxy signature. This paper presents the basic concept and related knowledge of elliptic curve proxy signature,discusses the present situation of the forward security. It gives an Elliptic curve proxy signature combines the forward security algorithm to be aimed at the Elliptic curve proxy signature which is one 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.
