  1. Multi-Party Computation (MPC) is an important technique used to enable computation over confidential data from several sources. The public cloud provides a unique opportunity to enable MPC in a low latency environment. Field Programmable Gate Array (FPGA) hardware adoption allows for both MPC acceleration and utilization of low latency, high bandwidth communication networks that substantially improve the performance of MPC applications. In this work, we show how designing arithmetic and Boolean Multi-Party Computation gates for FPGAs in a cloud provide improvements to current MPC offerings and ease their use in applications such as machine learning. We focus on the usage of Secret Sharing MPC first designed by Araki et al to design our FPGA MPC while also providing a comparison with those utilizing Garbled Circuits for MPC. We show that Secret Sharing MPC provides a better usage of cloud resources, specifically FPGA acceleration, than Garbled Circuits and is able to use at least a 10x less computer resources as compared to the original design using CPUs.
  2. Multi-Party Computation (MPC) is a technique enabling data from several sources to be used in a secure computation revealing only the result while protecting the original data, facilitating shared utilization of data sets gathered by different entities. The presence of Field Programmable Gate Array (FPGA) hardware in datacenters can provide accelerated computing as well as low latency, high bandwidth communication that bolsters the performance of MPC and lowers the barrier to using MPC for many applications. In this work, we propose a Secret Sharing FPGA design based on the protocol described by Araki et al. We compare our hardware design to the original authors' software implementations of Secret Sharing and to work accelerating MPC protocols based on Garbled Circuits with FPGAs. Our conclusion is that Secret Sharing in the datacenter is competitive and when implemented on FPGA hardware was able to use at least 10x fewer computer resources than the original work using CPUs.
