Security analysis on a kind of group signatures
In 1998, Lee and Chang proposed a group signature scheme based on the discrete logarithm problem.Tseng, Jan and Ao gave respectively new improved scheme based on Lee-Chang scheme. In this paper, we show there are still some security leaks in these schemes, and give some methods of forgery attack.
