| Abstract: | The concept of dynamic group signature was introduced. Dynamic group signature is a group signature, which allows the group manager to add new members or delete old members freely. An efficient and secure dynamic group scheme was given. Furthermore, the length of the signature, as well as the computational effort for signing and verifying, is independent of the number of group members and the number of deleted group members. |
