Abstract

Bei einem Verfahren zur Code-Sicherung für einen elek­ tronischen Schlüssel werden im Sender (1) und im Empfänger (2) eine Anzahl von Code-Nummern 1 bis n gespeichert und nach jedem Sende- und Empfangsvorgang im Sender (1) und Empfänger (2) eine neue übereinstimmende Code-Nummer selbsttätig eingestellt. Der vom Sender (1) ausgesandte Code enthält eine Information für den Empfänger (2), welche Code-­ Nummer als nächste aus dem gespeicherten Vorrat auszuwäh­ len ist.
