Abstract
- Laden eines Codewortes, eines Zeigers oder MAC's, welcher einem Codewortes zugeordnet ist, in einen ersten nichtflüchtigen Speicher (20 bzw. 25), der gegen Herausnahme und Manipulation abgesichert ist,
- Laden eines Codewortes oder eines mittels des Codewortes gebildeten MAC's in zweite die Postregisterdaten enthaltende zu schützende nichtflüchtige Speicher (NVM 5a, 5b), wobei das Codewort dem letzten Betriebszustand der Frankiermaschine zugeordnet ist,
- Gültigkeitsprüfung des Codewortes oder des mittels des Codewortes gebildeten MAC's mindestens zum Zeitpunkt des Einschaltens der Frankiermaschine und nachfolgend mindestens aufgrund einer Pseudozufallsfolge in Abständen,
- Ersetzen des alten Codewortes durch ein vorbestimmtes neues Codewort, wenn der Prozessor, nach Gültigkeitsprüfung die Gültigkeit des alten Codewortes oder oder die Gültigkeit des mittels des Codewortes gebildeten MAC's anerkennt oder
- Blockierung der Frankiermaschine nach dem Zeitpunkt des Einschaltens der Frankiermaschine, wenn der Prozessor nach Gültigkeitsprüfung die Gültigkeit des alten Codewortes oder die Gültigkeit des mittels des Codewortes gebildeten MAC's aberkennt.
