摘要

将前向安全的概念引入到代理签名体制

提出了一个前向安全的代理签名方案。新方案能实现即使代理签名人的代理签名密钥被泄露

以前所产生的代理签名依然有效。另外

新方案可以对代理签名的有效时间进行控制。

Abstract

A forward secure proxy signature scheme was proposed combining the concept of forward security with proxy signature. This means even if an adversary has gotten the current proxy signers’ key. It could not forge proxy signature pertaining to the past

that is

previous generated proxy signatures remain still valid. Furthermore

the scheme can control the proxy signature time of the proxy singer.
