mCrypton - does anyone know where I can find test vectors or a reference implementation?

I am currently writing an implementation of the mCrypton lightweight block cipher (as presented in this paper). Unfortunately, the authors do not provide any test vectors. I tried to contact the ...

Why commutativity gives an invariant subspace?

In A Generic Approach to Invariant Subspace Attacks the authors defined an invariant subspace as: $$F(u + A) = v + A$$ Where $F:\mathbb{F}_2^n \to \mathbb{F}_2^n$,$u, v \in \mathbb{F}_2^n$, and $A$ ...
