摘　　要：针对现有群签名的匿名范围不可变且应用上有一定局限性的问题,提出一种层次匿名群签名的概念.将成员所在的单位组织成层次架构,在生成群签名时根据具体的应用自主选择匿名层次,从而灵活适应不同匿名级别的需求.基于多变量多项式、RSA假设和知识签名等方法,构建一个高效的层次匿名群签名方案,将层次组织架构与作为密匙的多项式的解空间对应起来.Aiming at the problem that the anonymous range of the existing group signature is immutable and there are some limitations in application, a concept of group signature with hierarchical anonymous is proposed. The unit of members is organized into a hierarchical structure, when generating the group signature, the anonymous level is selected independently according to the specific application, so as to flexibly meet the needs of different anonymous levels. Based on multivariable polynomial, RSA assumption and knowledge signature methods, an efficient hierarchical anonymous group signature scheme is constructed, which corresponds the hierarchical organization structure to the solution space of the polynomial as the key.
