Secrecy: Secure collaborative analytics on secret-shared data

Abstract: In this talk I will present Secrecy, a new relational framework for secure collaborative analytics. Secrecy is based on replicated secret sharing and allows composing and executing end-to-end oblivious queries under secure multi-party computation (MPC). Secrecy’s core novelty is a set of logical and physical optimizations that effectively reduce query execution costs while retaining the full security guarantees of MPC. We evaluate Secrecy using real and synthetic queries from several application areas. Our experiments demonstrate that the optimizations we propose can improve query performance by orders of magnitude, enabling Secrecy to outperform state-of-the-art frameworks and scale to much larger datasets than those reported in prior works.
