Abstract

Properties of easily computable permutations specified in terms of a finite ring are investigated. It is established that problems of parametric identification for this class of permutations are reduced to the resolution of systems of Diophantine equations of sufficiently high degree and to the solution of systems of problems of taking discrete logarithms.
