OasisDB: An Oblivious and Scalable System for Relational Data
Summary: OasisDB composes oblivious KV-stores (PathORAM, Waffle) into a novel multi‑tier RDBMS that enables independent tier scaling and multi‑user obliviousness. Supports point/range queries, joins, aggregations and limited updates, scales linearly, and shows low overhead vs plaintext while improving scalability over ObliDB/Obliviator.
