摘要
给出一种新的基于身份的群成员和群管理员的群签名方案。由于新方案的构造不需要零知识证明,群签名的产生是由群成员和群管理员合作完成的,所以新方案具有结构简单、签名长度短、群成员的加入和撤销可以即时实现、群签名的跟踪快捷的优点。
A new ID-based group signature scheme, whose group managers and group members are all ID- based, is presented. Because the scheme does not require zero knowledge proof and the group signature is generated by a group member in collaboration with the group manager, the scheme has the advantages of simple structure, short signature length, concurrent join of users, immediate revocation of group mem-bers, easy tracing of group signatures.
