Abstract (in Japanese) (See Japanese page) 
(in English) We first propose a hierarchical structured multisignature scheme based on the Gap Diffie-Hellman(GDH) problem. We have expanded a standard GDH multisignature into a tree structured multisignature which can verify all signers' connection if footings of all signers over a tree structure can be shown [3]. In this paper, we explain the followings: if we consider signers on the same layer to be members in one group and have only to
distinguish a group from other groups, we can construct a hierarchical structured multisignature scheme which has more effective in performance than our tree structured signature scheme.
