| 摘 要： | 通过对杨丽等人提出的新型代理签名方案进行分析,指出该方案的代理签名验证算法是有缺陷的,会引起真正的原始签名人伪造攻击,针对方案的这个安全缺陷,提出了一种改进的代理签名方案,改进的新方案不仅可以抵抗原始签名人的攻击,而且提高了计算的效率.

| Abstract: | In this paper,through the cryptanalysis of a new proxy digital signature scheme proposed by Yang li,we have found that this scheme has leaks in verification algorithm which may cause the original signer's forgery attack on proxy signer. To avoid these attacks,we propose a new improved scheme. The new scheme can resist the original signer's forgery attack and improve the computation efficiency. |
