A new identity (ID)-based dynamic group signature scheme, in which group managers and group members are all ID-based, is presented in this paper. Different from traditional construction of group signatures, we use a new and efficient method to realize the anonymity and traceability. The performance evaluation shows that the signature length in our scheme is only about one-third of that in the short group signature scheme (Boneh et al., LNCS 3152, 2004).
