| 摘 要： | 周萍等人提出了一个前向安全代理盲签名方案，对该方案进行分析，指出该方案存在信息拥有者可以否认签名的问题，即信息拥有者否认用于签名的信息是自己提供的，该信息可能是伪造的.并在此基础上提出了改进的方案.实验表明改进的方案不仅具有原方案的优良特性，还解决了信息拥有者否认签名的问题.

| Abstract: | Professor Zhou Ping, et al. has proposed a scheme of forward secure proxy blind signature. This study analyzes the scheme, and points out the problems that information owners can deny the signature scheme. That is, the owner denies that the signature information is provided by themselves, which may be fake. The improvement is put forward based on the above analysis. The experiment shows that the improved scheme not only keeps the excellent qualities of the original plan, but also solves the problem of the information owner''s denial of signature. |
