We present Path ORAM, an extremely simple Oblivious RAM protocol with a small amount of
client storage. Partly due to its simplicity, Path ORAM is the most practical ORAM scheme …

A convolutional neural network (CNN) model represents a crucial piece of intellectual
property in many applications. Revealing its structure or weights would leak confidential …

Search indices are fundamental building blocks of many systems, and there is great interest
in running them on encrypted data. Unfortunately, many known schemes that enable search …

We propose a new tree-based ORAM scheme called Circuit ORAM. Circuit ORAM makes
both theoretical and practical contributions. From a theoretical perspective, Circuit ORAM …

Encrypted search algorithms (ESA) are cryptographic algorithms that support search over
encrypted data. ESAs can be designed with various primitives including …

Oblivious RAM (ORAM) is a cryptographic primitive that hides memory access patterns as
seen by untrusted storage. This paper proposes Ring ORAM, the most bandwidth-efficient …

This paper presents a new, co-designed compiler and architecture called GhostRider for
supporting privacy preserving computation in the cloud. GhostRider ensures all programs …

We present Onion ORAM, an Oblivious RAM (ORAM) with constant worst-case bandwidth
blowup that leverages poly-logarithmic server computation to circumvent the logarithmic …

Efficient, leakage-free search on encrypted data has remained an unsolved problem for the
last two decades; efficient schemes are vulnerable to leakage-abuse attacks, and schemes …

Realistic secure processors, including those built for academic and commercial purposes,
commonly realize an “attested execution” abstraction. Despite being the de facto standard …
