There are two important directions in group signature scheme: ID-Based group signature scheme and provably secure group signature scheme. In this paper, we first analyze the advantages and flaws of these two directions, and propose a provably secure ID-Based group signature scheme basing on the ACJT group signature scheme. Compared with prior ID-Based group signature scheme, our scheme is provably secure in random oracle model. Compared with the ACJT scheme, our scheme is ID-Based and strong non-repudiation.
