Abstract—A new ID-based group signature scheme, in which group managers (Membership Manager and Tracing Manager) and group members are all ID-based, is presented in this paper. Due to the nice constructive method of group signature schemes and the sound properties of bilinear pairing, it is shown that our scheme has the advantages of concurrent joining of users, immediate revocation of group members, easy tracing of signature signers and short length of signatures. Furthermore, it is trapdoor-free. The security analysis is under the formal security notion of an ID-based dynamic group signature scheme.

Index Terms—ID-Based Signature, Group Signature, Short Signature, Bilinear Pairing, Anonymity.
