A Network File Storage Model with Security and Information Retrieval Support

The rapid development of network technologies has seen the use of network as a media for file storage and sharing. Files stored on network are expected to be shared in a safe and effective manner. Most recent researches on secure network storage focus solely on security and give little concern to support for information retrieval and in turn information sharing. This paper presents a novel network storage model which integrates techniques in compression, encryption and information retrieval. It effectively satisfies the concern for both security and sharing. Its performance is also demonstrated via experiments on a prototype system.
