Abstract

Das Verfahren zur kryptologischen Authentifizierung in einem Radiofrequenz-Identifikations-System mit einer Basisstation, die einen mit dem zu identifizierenden Objekt verbundenen Transponder über das Wechselfeld eines Abfragesignals mit Energie versorgt, weist folgende Verfahrensschritte auf. Für die im wesentlichen gesamten Kommunikationen zwischen Basisstation und Transponder erzeugt die Basisstation ein Abfragesignal. Der Transponder antwortet bei Empfang des von der Basisstation gesendeten Abfragesignals mit einer in seinem Speicher abgelegten Identifikationsnummer. Daraufhin verschlüsselt die Basisstation eine von ihr generierte erste Bitfolge anhand einer Schlüsselbitfolge, die der Identifikationsnummer des Transponders zugeordnet ist und sendet die so erhaltene zweite Bitfolge zum Transponder. Beim Empfang der zweiten Bitfolge generiert der Transponder aus der zweiten Bitfolge eine Kontrollbitfolge und sendet diese nach vollständigem Empfang der zweiten Bitfolge an die Basisstation. Diese Kontrollbitfolge dient zur Überprüfung des richtigen Empfangs der zweiten Bitfolge. Zur Kryptographischen Authentifizierung verschlüsselt der Transponder die aus der zweiten Bitfolge rekonstruierte erste Bitfolge anhand der dem Transponder zugeordneten Schlüsselbitfolge und sendet die so erhaltene dritte Bitfolge zur Basisstation. Noch während der Transponder die zweite Bitfolge zur dritten Bitfolge verschlüsselt, überprüft die Basisstation anhand der Kontrollbitfolge, ob bei der Übertragung der zweiten Bitfolge ein Fehler aufgetreten ist, unterbricht gegebenenfalls die laufende Verschlüsselung im Transponder. Dadurch kann die laufende Authentifizierung unterbrochen werden, da nicht mit einem richtigen Ergebnis gerechnet werden kann. Es wird Zeit beim Start eines erneuten Durchlaufs des Authentifizierungsverfahrens gewonnen.
