顾名思义,代理签名让原始签名者可以将其数字签名权力委托给代理签名者,使其能够代理原始签名者签发指定的数字消息;盲签名使用户能将给定的消息让别人签发,而又不泄漏任何有关的信息给签名者.在Schnorr盲签名的基础上,谭作文等结合代理签名和盲签名提出了一个基于离散对数的代理盲签名方案.研究表明该方案是不安全的.它既受到广泛伪造攻击,又是可连接的.我们还进一步说明,原文安全性定理的证明是不正确的. As the name implies, the proxy signature allows the original signer to delegate its digital signature authority to the proxy signer so that it can proxy the original signer to issue the specified digital message; the blind signature enables the user to issue the given message to others without Leak any relevant information to the signer.Based on the Schnorr blind signature, Tan Zuowen et al. Proposed a proxy blind signature scheme based on discrete logarithm combined with proxy signature and blind signature. Is widely attacked and connected, and we further explain that the proof of the original security theorem is not correct.
