Summary:The threshold group signature is an important kind of signature. So far, many threshold group signature schemes have been proposed, but most of them suffer from conspiracy attack and are insecure. In this paper, a secure threshold group signature scheme is proposed.It can not only satisfy the properties of the threshold group signature, but also withstand the conspiracy attack.
