Abstract

Cloud storage services are becoming more widely used in recent decades. Lots of systems can protect stored information from being leaked by data encryption but it is difficult to protect data access pattern privacy with high efficiency compared to non-oblivious systems. Also, lots of Oblivious RAM (ORAM) systems developed by researchers are just proposed but not implemented in the real world due to high overheads in communication and storage. In this report, we implement a new Oblivious RAM (ORAM) system which dramatically decreases server storage capacity, lowers communication cost and reduces query delay. We also show that this ORAM system can protect client’s data access patterns.
