thc 0.1.1

Trustable homomorphic computation

Trustable homomorphic computation

THC is a Python package that provides a practical framework for cost-effective trustable homomorphic computation.

It leverages the modular extension technique, which was developed to protect embedded cryptographic implementations against fault injection attacks, to ensure the integrity of a computation delegated to an untrusted third-party.

Installation

You can either install THC using PyPI with the following command:

$ pip3 install thc

Or you can download its source code and run the following command in the root directory of the repository:

$ pip3 install .

You can check that the installation went well by running the included test demo:

$ python3 -m thc.demo.faults

Dependencies

THC depends on the pycrypto package to generate prime numbers.

You can probably install it using your distribution's package manager: it's the python3-crypto package on Debian and derivatives.

If you choose to let pip install pycrypto, you will need to have some Python development package installed as it needs to compile C extensions. On Debian and derivatives, the necessary packages are named python3-dev and python3-wheel.

Demo

In addition to the previously mentioned test demo of THC, an electronic voting software (server and client) is provided in the thc.demo.evoting package.

Please refer to its README for more information.
