    Abstract

    Oblivious RAM (ORAM) is a protocol to hide access pattern to an untrusted storage. ORAM prevents a curious adversary identifying what data address the user is accessing through observing the bits flows between the user and the untrusted storage system. Basically, ORAM protocols store user’s data in shuffled form on the untrusted storage and substitute the original access with multiple access to random addresses to cover the real target. Such redundancy introduce significant performance overhead.
