摘要
将前向安全的概念结合到代理签名体制中,利用椭圆曲线上的双线性对构造了一个基于双线性对的前向安全代理签名方案。此方案保护了原始签名者和代理签名者权益,攻击者即使在本时段入侵,也无法伪造过去时段的签名,有较高的效率和较强的安全性。
Combining the concept of forward security, an efficient proxy signature scheme based on bilinear pairings of elliptic curve is proposed. The signature scheme provides the safeguard to the rights and interests of both the original and the proxy signers. Even if an adversary can intrude and obtain the signature key at this time period, it could not forge the proxy signature of the past time. The scheme has high efficiency and strong security.
