On the key exchange and multivariate encryption with nonlinear polynomial maps of stable degree

Vasyl Ustimenko, Aneta Wroblewska

Abstract


We say that the sequence g^n, n 3, n ! 1 of polynomial transformation bijective mapsof free module K^n over commutative ring K is a sequence of stable degree if the order of g^n is growingwith n and the degree of each nonidentical polynomial map of kind g^n^k^ is an independent constant c.Transformation b = tgnk
