As a new cryptographic tool, attribute-based signature(ABS) allows user to sign messages using his attributes. The signature could be verified to satisfy some predicate without exposing any particular attributes or identity information of the signer. These properties effectively protect user's privacy while achieving attribute-based access control. In this paper, we propose an efficient threshold attribute-based signature scheme with constant signature size and constant pairing computation during verification. The scheme has been proved to be unforgeable and unconditionally anonymous. Compared with other existing constant-size ABS schemes, our scheme is short in signature size while keeps the secret key size acceptable.
Key words： attribute-based; digital signature; efficiency
