| Abstract: | In this paper, we propose an efficient group signature scheme whose public key and signatures have length independent of the number of group members and which allows the group manager to add new members to the group without modifying the public key. Furthermore, our scheme is secure and coalition-resistant under the RSA assumption and the decisional Diffie-Hellman assumption. |
