Abstract：Wang XM proposed a group signature scheme and claimed that it can resist all kinds of forgery attacks(2003). However，it was carefully analyzed, and there were defects in it: First, It cannot revoke group member effectively. Second，It cannot resist forgery attack.. In this paper, an effective attack scheme is proposed, and two factors that a secure group signature scheme should possess was given.
