A E-cash scheme base on structured multi-signature

A multi-signature scheme is a digital signature scheme that allows multiple signers to generate in a collaborative and simultaneous manner. A Structured multi-signature to exchange E-cash from bilinear pairings is proposed in this paper. This scheme can set up the order of signing in advance. and it can set up on the elliptic curve group and without using blind signature scheme, this scheme has many properties such an having simple structure, security, efficiency and so on. The security analysis show that it cam resist all kind of outsider and insider attackes.
