中文摘要：

针对闫东升提出的一个基于身份的部分盲签名方案和荣维坚提出的一个无证书部分盲签名方案,首先分析了这两个部分盲签名方案的不可伪造性,分析结果表明这两个方案都不能抵抗窜改协商信息攻击;然后分析了这两个部分盲签名方案的部分盲性,分析结果表明有关文献给出的对这两个方案的连接攻击都是无效的;最后指出Chow等人定义的安全模型和Zhang等人定义的安全模型都是不完善的。

英文摘要：

Recently,Yan proposed an identity-based partially blind signature scheme,and Rong proposed a certificateless partially blind signature scheme.At first,analyzed the unforgeability of the two proposed partially blind signature schemes.The analysis results show that the two schemes don＇t resist the changing agreed information attack.Secondly,researched the partial blindness of the two proposed partially blind signature schemes.The research results indicate that the linkability attack against the two schemes proposed by some people is invalid.Finally,it pointed out that Chow et al＇s model and Zhang et al.＇s model were not perfect.
