摘要
盲性是代理盲签名的一个重要特性。通过分析文献[1],发现其不具有盲性,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 Chen Ling- ling et al's one efficient id - based proxy blind signature shows that it doesn' t meet blindness. In this paper, an improvement is proposed, which not only mends the security risk but also retains the merits of the original id - based proxy blind signature scheme.
