SIMON/SPECK cryptanalysis code

Cryptanalysis code for the SIMON and SPECK families of block ciphers

Authors

This SIMON implementation and all cryptanalytic routines found in "simon.h" and "simon.cpp" were written by

• Martin M. Lauridsen (mmeh@dtu.dk) and
• Hoda A. Alkhzaimi (hoalk@dtu.dk)

Compilation

To compile the code, use the attached Makefile. You will see, that compilation flags include the C++11 standard and the OpenMP library ("omp.h"), so make sure you are using a version of gcc that supports C++11, and that you have the OpenMP library installed (or alternatively remove the parts of the code that uses OpenMP).

Documentation

We have not been very good at documenting the code, but in "simon.h", the different methods are categorized by their role in the different cryptanalytic approaches (differential, impossible differential, etc.).
