Introduction

This repository has the following components:

  • EzPC: a language for secure machine learning.
  • Athos (part of CrypTFlow): an end-to-end compiler from TensorFlow to a variety of semi-honest MPC protocols. Athos leverages EzPC as a low-level intermediate language.
  • Porthos (part of CrypTFlow): a semi-honest 3 party computation protocol which is geared towards TensorFlow-like applications.
  • Aramis (part of CrypTFlow): a novel technique that uses hardware with integrity guarantees to convert any semi-honest MPC protocol into an MPC protocol that provides malicious security.
  • SCI (part of CrypTFlow2): a semi-honest 2-party computation library for secure inference on deep neural networks.

Each one of the above is independent and usable in their own right and more information can be found in the readme of each of the components. But together these combine to make CrypTFlow a powerful system for end-to-end secure inference of deep neural networks written in TensorFlow.

With these components in place, we are able to run for the first time secure inference on the ImageNet dataset with the pre-trained models of the following deep neural nets: ResNet-50, DenseNet-121 and SqueezeNet for ImageNet.

For setup instructions, please refer to each of the components' readme. We plan to release a docker version of the system as well which will make the system easier to setup.
