HEFactory: Homomorphic Encryption Made Easy

HEFactory is a project aiming at bridging complex Homomorphic Encryption with Python. It is made of three different components:

  • Dahut
  • Tapir
  • Boar

Using HEFactory

It works in a simple way, by using symbolic executions. For example to perform a encrypted addition and multiplication we use:

with CGManager() as cgm:
    encrypted_a = CGSym(cgm, a) # Declare encrypted a
    encrypted_b = CGSym(cgm, b) # Declare encrypted b
    res = encrypted_a + encrypted_b # Perform encrypted sum

    cgm.output(res) # We declare our result

After the compilation of the CGManager finishes, we need to perform the execution. Boar automatically makes use of the generated files in order to compute the encrypted addition.

boar = Boar(verbose=True)
boar.launch()

Please check out the examples to learn more on how to use HEFactory.

Installation

The package can be installed through wheel, docker or building your own docker image. The recommended option is through docker.

Furthermore, we provide devcontainer and gitpod.io compatibility to test the software.

Wheel Installation

For the wheel installation, the following packages are required:

numpy
tensorflow
pulp
scikit-fuzzy
matplotlib

To install HEFactory: On x86-64:

pip3 install dist/linux_amd64/HEFactory-0.0.1-cp310-cp310-linux_x86_64.whl

On ARM64:

pip3 install dist/linux_arm64/HEFactory-0.0.1-cp310-cp310-linux_aarch64.whl

Docker Image

For x86-64:

docker run -it --rm jcabrero/hefactory:amd64 bash

For ARM based processors:

docker run -it --rm jcabrero/hefactory:arm64 bash

Building Docker Image from Scratch

cd docker/
make build
