摘要 对文献[4]提出的椭圆曲线代理数字签名方案进行了安全性分析,发现原签名方案不能够抵抗文中提出的两种伪造攻击。利用这两种伪造攻击的任何一种,原始签名者都能够伪造出一个有效的代理数字签名。对文献[4]的椭圆曲线代理数字签名方案进行了改进,提出了一种新的代理数字签名方案,能够完全抵抗文中的伪造攻击一和伪造攻击二。此外,还对改进的新方案进行了安全性分析和复杂度分析。 The security of elliptic curve proxy digital signature scheme by reference [4] is analyzed, the original signature scheme can not resist the two forgery attacks. Using anyone of the forgery attacks, original signer can produce a valid proxy signature. On the basis, an improved elliptic curve proxy digital signature scheme concerned is presented, and this improved scheme can completely resist the two forgery attacks. In addition, the security and complexity of this new scheme is analyzed.
