基于椭圆曲线的前向安全代理签名方案

A Forward-Secure Proxy Signature Scheme Based on Elliptic Curve Cryptosystem

为解决普通代理签名方案因代理签名密钥泄漏对系统造成的危害,提出一个基于椭圆曲线的前向安全代理签名方案,并在推广的强假定及椭圆曲线离散对数问题(ECDLP)难解的假定下,分析该方案的安全性。

A forward - secure proxy signature scheme based on elliptic curve cryptosystem was proposed to overcome the limitation of the ordinary proxy signature schemes. We analyzed the security of the new scheme under the generalized strong RSA assumption and the difficulty of elliptic curve discrete logarithm problem.
