In this paper,a secure multi-groups signature scheme is presented based on Kim et al.'s convertible group signature schemed.The new scheme can realize the single-group and the multi-groups signature,and can withstand the attacks proposed by Li.and Wang et al.to Kim et al.'s scheme.Furthermore,the new scheme provides a solution for deleting the members from a group or multi-groups.
