摘要：Security of cloud storage has drawn more and more concerns. In the searchable encryption, many previous solutions can let people retrieve the documents containing single keyword or conjunctive keywords by storing encrypted documents with data indexes. However, searching documents with a phrase or consecutive keywords is still a remained open problem. In this paper, using the relative positions, we propose an efficient scheme LPSSE with symmetric searchable encryption that can support encrypted phrase searches in cloud storage. Our scheme is based on non-adaptive security definition by R.Curtmola and with lower costs of transmission and storage than existing systems. Furthermore, we combine some components of currently efficient search engines and our functions to complete a prototype. The experiment results also show that our scheme LPSSE is available and efficient.
