SboxU: S-box Analysis Utils

Table of Contents

Work in progress

1 Installation

1.1 Dependencies

The SboxU library was only tested on Linux (Ubuntu 16.04). To install it, you need the following packages.

libboost-python-dev
libpython-dev
sage
cmake

1.2 Download

To retrieve this library, use the following command:

git clone https://github.com/lpp-crypto/sboxU/

Then, move to the `sbox-utils/sboxU` directory and run:

cmake .
make

This compiles the C++ part of sboxU and allows it to be called from a SAGE script. To use it in your project, simply move the sboxU folder to your project's directory. You can then import sboxU like any other python module. As an example of the functions provided by sboxU, the SAGE script example.py stored alongside the folder sboxU generates random permutations and tests their affine equivalence.
