Abstract

En underkonverter (330) tilveiebrakt i en dataomformingsanordning for kryptering/dekryptering av data har en dataomformingsfunksjon og en dataoverføringsfunksjon eller nøkkeloverføringsfunksjon, og omformer data og overfører data som er ikke-lineært omformet i en hovedkonverter (320) eller en nøkkel som er matet ut fra et key KL-register (240) ved å skifte mellom dataomformingsfunksjonen og data- eller nøkkeloverføringsfunksjonen
