Abstract—A new ID-based group signature scheme, in which group managers and group members are all ID-based, is presented in this paper. Our scheme is obtained by using a new way to the construction of group signature schemes and based on an ID-based signature scheme from bilinear pairing. Due to the nice and simple constructive method and the sound properties of bilinear pairing, it is shown that the proposed scheme is very simple and practical and has the advantages of concurrent join, immediate revocation, easy tracing and short signature length. The security analysis is also under the formal security notion of an ID-based group signature scheme.
