Local Inversion of maps:\\Black box Cryptanalysis. (arXiv:2207.03247v1 [cs.CR])

This paper is a short summery of results announced in a previous paper on a
new universal method for Cryptanalysis which uses a Black Box linear algebra
approach to computation of local inversion of nonlinear maps in finite fields.
It is shown that one local inverse $x$ of the map equation $y=F(x)$ can be
computed by using the minimal polynomial of the sequence $y(k)$ defined by
iterates (or recursion) $y(k+1)=F(y(k))$ with $y(0)=y$ when the sequence is
periodic. This is the …
