摘要： 在MR到签名方案和ELGamal型签名方案上，他们提出了3个具有特殊次序的多重签名方案。利用这些方案，验证者可以验证签名者的次序，只有遵循特殊次序的签名才会被接受。文章首先介绍了3个最基本的签名方案，其次3个新方案被建立起来并讨论了它们的安全性.

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.
