We show that PRAMs can be obliviously simulated with perfect security, incurring only O(logNloglogN) blowup in parallel runtime, O(log3N) blowup in total work, and O(1) blowup in space relative to the...

Oblivious Parallel RAM (OPRAM), first proposed by Boyle, Chung, and Pass, is the natural parallel extension of Oblivious RAM (ORAM). OPRAM provides a powerful cryptographic building block for hiding t...

Oblivious RAM (ORAM) is a cryptographic primitive that allows a client to access memory locations from a server without revealing its access patterns. Oblivious Parallel RAM (OPRAM) is a PRAM counterp...

An Oblivious Parallel RAM (OPRAM) provides a general method to simulate any Parallel RAM (PRAM) program, such that the resulting memory access patterns leak nothing about secret inputs. OPRAM was orig...
We initiate the study of cryptography for parallel RAM (PRAM) programs. The PRAM
model captures modern multi-core architectures and cluster computing models, where several
processors execute in para...

In this paper, we describe efficient protocols to perform in parallel many reads and writes
in private arrays according to private indices. The protocol is implemented on top of the
Arithmetic Black...

Oblivious RAM (ORAM) garbles read/write operations by a
client (to access a remote storage server or a random-access memory) so
that an adversary observing the garbled access sequence cannot infer a...
