Abstract

Die Erfindung betrifft ein nichtlinear rückgekoppeltes Schieberegister (1; 22; 23; 24) zur Erstellung einer Signatur für kryptografische Anwendungen, mit einer Folge von in Reihe geschalteter Flipflops (2...6; x0...xn-1), die zur Bildung zumindest eines Polynoms mittels zumindest einer wenigstens einen Operator (9, 10, 12) aufweisenden Signalrückführung (7) miteinander verschaltet sind. Es ist vorgesehen, dass die Flipflops (2...6; x0...xn-1) zur Bildung von mindestens zwei unterschiedlichen Polynomen mit mindestens einem Umschaltoperator (13) verschaltet sind, der in Abhängigkeit eines Eingangssignals zwischen den Polynomen umschaltet. Ferner betrifft die Erfindung ein Verfahren zur nicht linearen Signaturbildung.
