摘　　要：前向安全的椭圆曲线代理签名方案有效地解决了由于签名者泄露私钥对签名带来的危害,但是攻击者可能利用其他非技术性手段,比如说骗取、偷盗等来获得代理签名,这时就会对代理签名产生一个致命的危害。在此基础上,利用强前向安全的原理结合椭圆曲线的优点有效解决了这个问题。Forward secure proxy signature scheme based on elliptic curve effectively solves the harm because of the leakage of the private key, But an attacker could exploit other non-technical means such as fraud, theft to get proxy signature, then it will produce a fatal harm to proxy signature, This paper effectively solved this problem based on strong forward security and the advantages of elliptic curve.
