A conjunctive keyword searchable encryption scheme makes it possible to retrieve several keywords in encrypted data at one time. In this paper, we present a conjunctive keyword searchable encryption with constant pairing, short ciphertext and trapdoor in the standard model. We also propose two concrete constructions and give their security analysis. The first scheme is constructed in composite order groups model and the second scheme is implemented in prime order groups model. Under assumed standard model, our proposed schemes achieve higher computation efficiency and shorter ciphertext/trapdoor, which have flexible applications in multiple keywords search and filter such as email filtering, firewall and copyright protection.
