Juliet

An Execution Engine for an Encrypted Processor

Prerequisites

Install TFHE
Update library path if necessary:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:<TFHE_INSTALL_DIR>/lib
export LIBRARY_PATH=$LIBRARY_PATH:<CUFHE_DIR>/cufhe/bin
export CPLUS_INCLUDE_PATH=$CPLUS_INCLUDE_PATH:<CUFHE_DIR>/cufhe/include

Overview

Juliet is a framework for general-purpose computation with Fully Homomorphic Encryption (FHE).

docker build -t juliet .

docker run --rm -i -t juliet bash

Client Setup

Run make client_scripts_cpu for the CPU-based TFHE backend or make client_scripts_gpu for the cuFHE GPU-based backend.
Navigate to the client directory and run ./keygen.out to generate an FHE keypair. The evaluation key needed for FHE operations will be placed in the cloud_enc directory.
Create a file named preAux.txt and load this with cleartext integer inputs (one per line) that represent sensitive data and will serve as sensitive program inputs for Juliet.
Run ./ppscript.sh to automatically generate a ciphertext memory directory, which will be placed in the cloud_enc directory.
Upload the entire cloud_enc directory to the cloud server.
