Abstract: A group signature scheme based on discrete logarithm is proposed .It can avoid the common forgery attack of the group member and the group manager. Compared with the existing group signature scheme, the scheme has relatively small computational complexity, and the amount of data need to be transferred is very small, so this scheme is relative efficient.
