Attribute Based Multi-signature Scheme in the Standard Model

Attribute based signature scheme is an important cryptographic primitive which provides a powerful way for users to control their privacy. Due Attribute based signature scheme is an important cryptographic primitive which provides a powerful way for users to control their privacy. Due to the fact that it can reduce the bandwidth needed to transmit attribute based signatures and the time needed to verify the signature at the same time, attribute based multi-signature scheme (ABMS) is proposed in this paper. We also formalized ABMS scheme and proved the security of this scheme in the standard model. The analysis shows that our ABMS scheme has less signature length and needs less computing verification than the traditional ABS scheme. to the fact that it can reduce the bandwidth needed to transmit attribute based signatures and the time needed to verify the signature at the same time, attribute based multi-signature scheme(ABMS) is proposed in this paper.
