Query: CrypTFlow: Secure TensorFlow Inference   We present CrypTFlow, a first of its kind system that converts TensorFlow
inference code into Secure Multi-party Computation (MPC) protocols at the push
of a button. To do this, we build three components. Our first component, Athos,
is an end-to-end compiler from TensorFlow to a variety of semi-honest MPC
protocols. The second component, Porthos, is an improved semi-honest 3-party
protocol that provides significant speedups for TensorFlow like applications.
Finally, to provide malicious secure MPC protocols, our third component,
Aramis, is a novel technique that uses hardware with integrity guarantees to
convert any semi-honest MPC protocol into an MPC protocol that provides
malicious security. The malicious security of the protocols output by Aramis
relies on integrity of the hardware and semi-honest security of MPC. Moreover,
our system matches the inference accuracy of plaintext TensorFlow.
  We experimentally demonstrate the power of our system by showing the secure
inference of real-world neural networks such as ResNet50 and DenseNet121 over
the ImageNet dataset with running times of about 30 seconds for semi-honest
security and under two minutes for malicious security. Prior work in the area
of secure inference has been limited to semi-honest security of small networks
over tiny datasets such as MNIST or CIFAR. Even on MNIST/CIFAR, CrypTFlow
outperforms prior work.
