Abstract

Es wird eine programmgesteuerte Einheit beschrieben, mit einer Speichereinrichtung, auf welche von verschiedenen anderen Komponenten der programmgesteuerten Einheit lesend oder schreibend zugegriffen werden kann. Die beschriebene programmgesteuerte Einheit zeichnet sich dadurch aus, dass bei Zugriffen auf die Speichereinrichtung überprüft wird, ob der jeweilige Zugriff durch eine dazu nicht autorisierte Person veranlasst wurde oder veranlasst worden sein könnte, und dass die Speichereinrichtung angeforderte Daten nur ausgibt, und/oder ihr zugeführte Daten nur speichert, wenn die Überprüfung ergeben hat, dass davon ausgegangen werden kann, dass der betreffende Zugriff nicht durch eine dazu nicht autorisierte Person veranlasst wurde oder veranlasst worden sein könnte.
