CCD

This project aims to provide OpenShift projects with a simple interface to perform secure multi-party computation (MPC) over data stored on Dataverse and Swift. Using the CCD system, analysts can compute aggregate statistics from multiple private datasets without the raw data itself being revealed during the computation. Additionally, data owners are able to provide specific policy constraints that describe exactly which kinds of computations may be performed.

At it's core, CCD is an implementation of conclave, a relational query compiler for MPC workflows. Conclave automatically transforms SQL-like queries into a series of local and secure computations such that as little actual MPC is done as possible. In doing so Conclave is able to, in certain cases, scale to realistically-sized datasets while still delivering the security guarantees of MPC.
