| 摘 要： | 文献4]、5]设计出各自的代理盲签名方案,旨在克服伪造攻击。通过对这两个方案进行分析,提出了一个伪造攻击方法。任何人都可以用该攻击方式欺骗代理签名者并让其产生有效的签名,从而表明该方案不安全。该伪造攻击的提出,为设计新的代理盲签名方案提供有效的参考。

Security Analysis of Two Proxy Blind Signature Schemes |
| |
| Abstract: | Two proxy blind signatures were designed in literature 4],5], in which was introduced to overcome forgery attacks. In this paper, we present a forgery attack approach against their vulnerabilities after analyzing these two schemes, the approach can be used by anyone to deceive the attack the proxy signer and let its produce a valid signature, so that it demonstrates these two schemes are not secure. What we done provides some references to the researchers on designing new proxy blind signatures. |
