Abstract :
A group signature scheme with no group manager is proposed in this paper. The proposed scheme allows that any t or more group members collectively add new members or delete group members without the group manager. Furthermore, the length of a signature and the computational effort for signing and verifying do not depend on the number of the deleted group members. The scheme has many practical applications in full decentralized and lack centralized control environments.
