The SPARX source code package includes various implementation of SPARX, a family of lightweight block ciphers.

The SPARX webpage gives links to detailed specs, design rationale, security proofs, and many more.

In the repository you will find the following directories:

Run make in ref-c directory to build the executables sparx_64_128, sparx_128_128 and sparx_64_256. Run make test to verify that your build produces valid results.

The optimized assembly implementations are designed to work with the FELICS framework. See FELICS for details on how to use them.

For detailed benchmarks on embedded platforms see FELICS.
