Abstract: Based on MR type signature schemes and ELGamal type signature scheme, they pr0pose three multisignature schemes by which a verifier can identify the order of signing groups.In these proposed scheme, only the signatures with the specified order of groups is accepted as valid.In this Paper,three signature schenus are showed at first, next, three new signature scheme is constructed and their security is considered.
