Lattice-based Cryptanalysis Toolkit

This repository implements a toolkit for cryptanalysis using lattice reduction built for experimenting and learning. Check out the accompanying tutorial for some background.

Installing

The toolkit can be used with both Python and Sage. To get started, clone the repository:

git clone https://github.com/josephsurin/lattice-based-cryptanalysis.git

Then run

cd lattice-based-cryptanalysis
pip install .

and/or (to make it available within Sage)

cd lattice-based-cryptanalysis
sage -pip install .

The lbc_toolkit module is then available to import functions from:

from lbc_toolkit import hnp

---

The toolkit can also be used without installing via pip. Add the repository's location to the PYTHONPATH environment variable:

export PYTHONPATH="/path/to/lattice-based-cryptanalysis:$PYTHONPATH"

The lbc_toolkit module is then available to import functions from:

from lbc_toolkit import hnp

As an alternative to setting PYTHONPATH, modifying sys.path works too:

import sys
sys.path.append('path/to/lattice-based-cryptanalysis')

from lbc_toolkit import hnp

Examples

The examples/ directory contains usage examples of almost all of the available functions.

Documentation

Some documentation for the available functions can be found at docs/.
