Silph: A Framework for Scalable and Accurate Generation of Hybrid MPC Protocols
Authors: Edward Chen, Jinhao Zhu, Alex Ozdemir, Riad S. Wahby, Fraser Brown, Wenting Zheng
Abstract:Many applications in finance and healthcare need access to data from multiple organizations. While these organizations can benefit from computing on their joint datasets, they often cannot share data with each other due to regulatory constraints and business competition. One way mutually distrusting parties can collaborate without sharing their data in the clear is to use secure multiparty computation (MPC). However, MPC’s performance presents a serious obstacle for adoption as it is difficult for users who lack expertise in advanced cryptography to optimize. In this paper, we present Silph, a framework that can automatically compile a program written in a high-level language to an optimized, hybrid MPC protocol that mixes multiple MPC primitives securely and
efficiently. Compared to prior works, our compilation speed is improved by up to 30000×. On various database analytics
and machine learning workloads, the MPC protocols generated by Silph match or outperform prior work by up to 3.6×.
