In this paper, we construct an Attribute-Based Signature (ABS) scheme for general circuits from multilinear maps. Our scheme is inspired by Garg et al.’s Attribute-Based Encryption (ABE) scheme at CRYPTO 2013. We prove selective unforgeability of our scheme in the standard model under the Multilinear Computational Diffie-Hellman (MCDH) assumption. The privacy security of our scheme is perfect.
