Side-Channel Analysis Library

The Side-Channel Analysis Library (SCALib) is a Python library that contains state-of-the-art tools for side-channel security evaluation.

• Documentation: https://scalib.readthedocs.io/

• Examples: examples/

• Chat: https://matrix.to/#/#scalib:matrix.org <https://matrix.to/#/#scalib:matrix.org>

• Source code: https://github.com/simple-crypto/SCALib

• Bug reports/feature requests: https://github.com/simple-crypto/SCALib/issues/new/choose

• Contributing: https://scalib.readthedocs.io/en/stable/source/contributing.html

SCALib focuses on

• simple interface,

• state-of-the art algorithms,

• excellent performance (see benchmarks).

SCALib should be useful for any side-channel practitioner who wants to evaluate, but not necessarily attack, protected or non-protected implementations. See the documentation for the list of implemented tools.

Install

SCALib is on PyPi! Simple install:

pip install scalib

We provide pre-built wheels for any recent python on Linux and Windows (x86). Be sure to use a recent pip. For other plateforms, this will build SCALib (see below for dependencies).

Local build

To get best performance, you want to build locally (this will optimize SCALib for your CPU).

Depdendencies:

• python >= 3.8,

• the python build module (available on PyPI),

• a C/C++ compiler for your platform,

• clang (version 5.0 or later),

• the latest stable release of the rust toolchain.

To install from source:

git clone https://github.com/simple-crypto/SCALib
cd SCALib
pip install .

See CONTRIBUTING.rst for advanced build configuration.

Usage

See API documentation, example and real-world usages.
