This paper surveyed the definition and security model of group signature, main constructions which were classified as ROM based and standard model based. It discussed the different construction techniques and methods, and compared them with each other. It also surveyed the main ways to achieve member revocation for group signature, and discussed the relations between group signature and a couple of similar cryptosystems. Finally, this paper presented some further research directions for group signature.
