We present a 2-cloud oblivious storage (ORAM) system that achieves 2.6 X bandwidth cost
between the client and the cloud. Splitting an ORAM across 2 or more non-colluding clouds …

Encryption alone is not enough to protect data privacy, because access pattern leaks some
sensitive information. Oblivious RAM (ORAM), the solution to this problem, is still far from …

To understand the gap between theory and practice for oblivious cloud storage, we
experimentally evaluate four representative Oblivious RAM (ORAM) designs on Amazon S3 …

Multi-user oblivious storage allows users to access their shared data on the cloud while
retaining access pattern obliviousness and data confidentiality simultaneously. Most secure …

We consider oblivious storage systems hiding both the contents of the data as well as
access patterns from an untrusted cloud provider. We target a scenario where multiple users …

We design and build ObliviStore, a high performance, distributed ORAM-based cloud data
store secure in the malicious model. To the best of our knowledge, ObliviStore is the fastest …

Oblivious RAM (ORAM) has emerged as an enabling technology to secure cloud-based
storage services. The goal of this cryptographic primitive is to conceal not only the data but …

We present Ring ORAM, a simple and low-latency ORAM construction that can be
parameterized for either small or large client storage. Simply by tuning parameters, Ring …

Along with the popularity of outsourcing data to the cloud server, data privacy becomes a
central consideration. Because encryption alone has been proved insecure for the leakages …

Existing oblivious storage systems provide strong security by hiding access patterns, but do
not scale to sustain high throughput as they rely on a central point of coordination. To …
