5gen-c: circuit-based obfuscation

This repository contains files necessary for building and evaluating circuit-based obfuscators. It contains both a build script, build.sh, and a Dockerfile for building all the necessary dependencies. We recommend using docker to set up an appropriate environment, although build.sh works as well assuming all the dependencies are already installed.

Building with docker

We supply a Dockerfile for building the system. To build, run:

docker build -t 5gen-c .

Then, to run the docker container, run:

docker run -it 5gen-c /bin/bash

Once in the container, run the following to build the code:

git pull origin master
./build.sh

If you don't want/need to build cxs (which takes a long time), run:

docker build -t 5gen-c-no-cxs - < Dockerfile-no-cxs

And then to run the container:

docker run -it 5gen-c-no-cxs /bin/bash

Building 5gen-c is similar to above, except now we don't want to build cxs:

git pull origin master
./build.sh --no-cxs

Building with build.sh

build.sh has several options:

• --debug builds the code in debug mode
• --clean removes all executables and build files

Running build.sh with no options will build everything.

Running

Once built, there are several scripts available in the main directory for both generating and obfuscating circuits. In addition, scripts for running the obfuscator on all available circuits can be found in circ-obfuscation/scripts. In particular, circ-obfuscation/scripts/test.sh will run the obfuscator on all circuits in circ-obfuscation/circuits.
