- The work is to build a data shuffling capability on Intel SGX platform in a unique way that is both strongly secure (or oblivious memory access) and efficient. The key idea to lower performance overhead without sacrificing strong security is the notion of cache-miss obliviousness. Upon implementation, the cache-miss obliviousness is realized by leveraging Intel TSX features.

- The work is to build a database system on top of multiple private-data sources. A user can submit a regular SQL query to our database which evaluates the query among data sources while preserving the privacy of each data source. Comparing existing work on applied multi-party computations (MPC), our work is distinct in building real MPC-based systems.
