Compressed Oblivious Encoding for Homomorphically Encrypted Search
Seung Geol Choi, Dana Dachman-Soled, S. Dov Gordon +2
Fully homomorphic encryption (FHE) enables a simple, attractive framework for secure search. Compared to other secure search systems, no costly setup procedure is necessary; it is…
Deterministic, Stash-Free Write-Only ORAM
Daniel S. Roche, Adam J. Aviv, Seung Geol Choi +1
Write-Only Oblivious RAM (WoORAM) protocols provide privacy by encrypting the contents of data and also hiding the pattern of write operations over that data. WoORAMs provide bette…
POPE: Partial Order Preserving Encoding
Daniel S. Roche, Daniel Apon, Seung Geol Choi +1
Recently there has been much interest in performing search queries over encrypted data to enable functionality while protecting sensitive data. One particularly efficient mechanism…
ObliviSync: Practical Oblivious File Backup and Synchronization
Adam J. Aviv, Seung Geol Choi, Travis Mayberry +1
Oblivious RAM (ORAM) protocols are powerful techniques that hide a client's data as well as access patterns from untrusted service providers. We present an oblivious cloud storage…
A Practical Oblivious Map Data Structure with Secure Deletion and History Independence
Daniel S. Roche, Adam J. Aviv, Seung Geol Choi
We present a new oblivious RAM that supports variable-sized storage blocks (vORAM), which is the first ORAM to allow varying block sizes without trivial padding. We also present a…
