Abstract

Abstract

A new forgery attack is proposed to Tseng-Jan s group signature scheme(1999), anyone can produce a valid group signature with this forgery attack. In this paper, a new modified and secure group signature scheme is presented in point of the forgery attacks proposed by this paper and Z.C. Li, et al.(2000). The new scheme can not only resist all kinds of forgery attacks, but also preserve the main merits in Tseng-Jan s scheme. Furthermore, the new scheme can revoke group member according to need.
