In recent work published at ACM CCS 2013 [5], we introduced Phantom, a new secure processor that obfuscates its memory access trace. To an adversary who can observe the processor’s output pins, all memory access traces are computationally indistinguishable (a property known as obliviousness). We achieve obliviousness through a cryptographic construct known as Oblivious RAM or ORAM. Existing ORAM algorithms introduce a fundamental overhead by having to access signicantly more data per mem
