In this paper, we propose an efficient group signature scheme whose public key and signatureshave length independent of the number of group members and which allows the group manager to add newmembers to the group without modifying the public key.Furthermore, our scheme is secure and coalitionresistantunder the RSA assumption and the decisional Diffie-Hellman assumption.
