Abstract

Eine Mikroprozessoranordnung umfaßt einen Datenbus (4) zur Datenübertragung zwischen Funktionseinheiten (1, 2, 3). Jede Einheit enthält busseitig eine Ver-/Entschlüsselungseinrichtung (11, 21, 31), die synchron von einem Zufallsgenerator (6) gesteuert werden. Die Anordnung ermöglicht eine relativ hohe Abhörsicherheit der über den Datenbus übertragenen Daten bei vertretbarem zusätzlichem Schaltungsaufwand.
