AFF3CT Post-Quantum Cryptography Modules

AFF3CT is a simulator and a library dedicated to the Forward Error Correction (FEC or channel coding). This repository implements software modules for the support of Post-Quantum Cryptography schemes in AFF3CT. The currently supported encryption schemes are Bike, Classic McEliece and Hamming Quasi-Cyclic (HQC).

The implementation relies on the following dependences:

• The FLINT Fast Library for Number Theory (successfully tested with v3.1.3).
• AFF3CT's StreamPU task-based runtime system for streaming (successfully tested with v1.2.3)

FLINT

FLINT is detected using the pkg-config command. FLINT's installation pkgconfig/' directory and the corresponding pkgconfig/directories of its own dependencies (GMP and MPFR libs) should all be listed in thePKG_CONFIG_PATH` environment variable.

StreamPU

StreamPU should either:

• be preinstalled, with its prefix install directory listed in the CMAKE_PREFIX_PATH environment variable;
• or be extracted as a git repository in the streampu/ subdirectory of the PQC modules sources, in which case it will be built as part of the process.

Building the PQC library and examples

Example programs in subdirectory examples/ illustrate the construction of encrypting / decrypting communication chains for each of the supported schemes.

The library and examples should be compiled as follows:

export PKG_CONFIG_PATH="<FLINT and dependencies pkgconfig dirs>:${PKG_CONFIG_PATH}"
export CMAKE_PREFIX_PATH="<StreamPU install dir prefix>:${CMAKE_PREFIX_PATH}"
cmake -DCMAKE_INSTALL_PREFIX='<PQC install dir prefix>' -S '<PQC source dir>' -B '<PQC build dir>'
cmake --build '<PQC build dir>'
cmake --install '<PQC build dir>'
