摘要
提出了一种新型的代理盲签名方案,它解决Tan等人提出的代理盲签名方案(谭方案)中存在的2个问题:①伪造性.原始签名者或签名接受者能伪造任何文件的代理盲签名.②追踪性.代理者能够把生成代理盲签名的行为与去盲后得到的真实文件签名关联起来.因此,新方案具有更高的安全性.
A new proxy blind signature scheme is proposed to resolve two issues in the Tan＇s proxy blind signature scheme： ① Forgeability. Both original signer and signature receiver can forge a valid proxy blind signature for any file. ② Traceability. The proxy signer can relate the formation process of the proxy blind signature to the unblind signature for the file. Therefore, the new scheme is of more security.
