Abstract
The Public Key Encryption with Conjunctive Keyword Search (PECK) scheme enables one to search a document included multiple encrypted keywords without compromising any original data information. The existing PECK schemes mostly depend on pairings and authenticated channel to achieve searchable encryption. In this paper, we propose a new PECK scheme based on pairings, where no pairing operations are involved in the encryption and trapdoor phases and no secure channel is needed between server and users. In comparison with previous schemes, our scheme can achieve high efficiencies in both computation and communication. And then we further discuss on the consistency, efficiency and security of the proposed scheme.
