摘要
盲性是代理盲签名的一个重要特性.分析杜焕强等人的基于身份代理盲签名后发现其不具有盲性,本文对其进行了改进,改进后的方案克服了原方案的安全隐患,并且保留了原方案的其它优点.
The blindness is an important property of a proxy blind signature scheme. Analysis of Du Huan-qiang et al's id-based proxy blind signature shows that it doesn't satisfy blindness. In this paper, an improvement is proposed, which not only mends the security leak but also retains the merits of the original id-based proxy blind signature scheme.
