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中存在的2个问题:⑴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。⑵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。

关键词: 代理签名, 盲签名, 代理盲签名

Abstract:

In a proxy blind signature scheme, the proxy can blindly sign the file for the delegated signer. In the paper, we propose a new proxy blind signature scheme, which resolves two issues in the Tan’s proxy blind signature scheme: ⑴Security, both original signer and signature receiver can forge a valid proxy blind signature for any file. ⑵Traceability, the proxy signer can relate the process of the proxy blind signature to the unblind signature for the file.

Key words: Proxy signature, Blind signature, Proxy blind signature;
