Abstract. In this paper, we present a new construction of expressive attribute-based signature scheme which is proven existentially unforgeable in the standard model for the selective adversary. In addition, this scheme can also achieve perfect privacy, which means the signature reveals nothing about the identity or attribute information about the real signer. Compared with other existing attribute-based signature schemes that can support the general access structure, the new construction provides better efficiency in terms of the computation cost and signature size.
