A group signature scheme allows any group member to sign on behalf of the group in an anonymous and unlinkable fashion. In the event of a dispute, a designated trusted entity can reveal the identity of the signer. In this paper we propose a revocation method for group signatures based on the group signature scheme from C. Popescu., (2000). This method requires no time periods and offers constant length signatures.
