Abstract

What is described is a falsification-proof electronic lock system which consists of an electronic key and a lock control. According to the invention, a dialogue based on question-and-answer code signals is conducted between these two modules, an actuation of the bolt of the lock becoming possible only after a respective parts dialogue has been acknowledged.

Description

einen Empfänger 10, einen Fest- und Lesespeicher 11, einen Codevergleicher 12, einen Datenauswerter 13, einen Zähler- und Zeitschalter 14 und ein Verweigerungsglied 15 — und einen Zufallsgenerator 16 enthält. Sämtliche Bauteile sind in der erforderlichen funktionellen Weise miteinander verschaltet.a receiver 10, a read-only memory 11, a code comparator 12, a data evaluator 13, a counter and time switch 14 and a denial element 15 - and a random generator 16 contains. All Components are interconnected in the required functional manner.

Soll nun beispielsweise das Schloß 17 der Kraftfahrzeugtür entriegelt werden, so wird vom elektrischen Schlüssel 2 über dessen Sender 4 ein im Speicher 5 fest programmiertes Öffnungscodesignal 18, z. B. als Infra- ίο rot-, Ultraschall- oder Funksignal, an den Empfänger 10 der Schloßsteuerung 3 ausgesendet. Deren Codevergleicher 12 vergleicht das empfangene öffnungscodesignal 18 mit einem in dem Fest- und Lesespeicher 11 fest gespeicherten Codesignal. Stimmen die beiden Codesignale überein, so wird von dem Datenauswerter 13 ein Schaltsignal erzeugt, welches den Fest- und Lesespeicher 11 zur Abgabe von fest gespeicherten Fragecode 19 an den Zufallsgene'rator 16 aktiviert. Dieser mischt die Fragecode 19 willkürlich und sendet diese als Zufallscodesignal 20 zum einen an den elektronischen Schlüssel 2 und zum anderen an den elektronischen. Baustein 9 aus, wo es in den Lesespeicher 11 eingeschrieben wird. Das vom elektronischen Schlüssel 2 empfangene Zufallscodesignal 20 wird in dessen Codevergleicher 6 mit im Speicher 5 fest programmierten Antwortcode 21 verglichen — der Speicher 5 enthält zu jedem Zufallscodesignal 20 einen genau definierten Antwortcode 21 —, wobei bei Bestätigung der beiden Code über die Datensteuerung 7 und Datenausgabe 8 der Sender 4 zur Aussendung eines Antwortcodesignals 22 aktiviert wird. Das vom Empfänger 10 empfangene Antwortcodesignal 22 wird nun wiederum im Codevergleicher 12 mit dem in den Lesespeicher 11 eingeschriebenen Zufallscodesignal 20 verglichen und — da die beiden Signale 22 und 20 nicht identisch sind bzw. sein müssen — vom Datenauswerter 13 verarbeitet, welcher bei Bestätigung der beiden Codesignale 22 und 20 ein Signal 23 zur Entriegelung des Schlosses 17 abgibt.If, for example, the lock 17 of the motor vehicle door is to be unlocked, the electrical Key 2 via its transmitter 4 a permanently programmed opening code signal 18 in memory 5, e.g. B. as Infra- ίο red, ultrasonic or radio signal sent to the receiver 10 of the lock control 3. Their code comparator 12 compares the received opening code signal 18 with one in the read-only memory 11 stored code signal. If the two code signals match, the data evaluator 13 outputs a Switching signal generated, which the read-only memory 11 for the delivery of permanently stored question code 19 to the random generator 16 activated. This randomly mixes the question code 19 and sends it as a random code signal 20 on the one hand to the electronic key 2 and on the other hand to the electronic key. Block 9 from where it is written into read-only memory 11. That from the electronic key 2 The random code signal 20 received is programmed into its code comparator 6 with fixedly programmed in the memory 5 Response code 21 compared - the memory 5 contains a precisely defined one for each random code signal 20 Response code 21 -, with confirmation of the two codes via the data control 7 and data output 8 the transmitter 4 is activated to transmit a response code signal 22. The one received by the receiver 10 The response code signal 22 is now again written into the code comparator 12 with the one written into the read-only memory 11 Random code signal 20 compared and - since the two signals 22 and 20 are not or be identical must - processed by the data evaluator 13, which upon confirmation of the two code signals 22 and 20 a Signal 23 for unlocking the lock 17 emits.

Hat nun ein Unbefugter den gesamten Dialog zwisehen elektronischem Schlüssel 2 und Schloßsteuerung 3 aufgezeichnet, also die Signale 18,20 und 22, so führt die Benutzung dieser Aufzeichnung trotzdem nicht zur Erzeugung des Signals 23 zum Entriegeln des Schlosses 17, da bei jeder Abgabe des Öffnungscodesignals 18 ein anderes Zufallscodesignal 20 und Antwortcodesignal 22 erzeugt wird. Selbst eine mehrfache Benutzung des aufgezeichneten Dialoges durch den Unbefugten führt nicht zu einer zufälligen Erzeugung des Signals 23, da in einer weiteren Ausgestaltung des Erfindungsgegenstandes als weitere Sicherheitsvorkehrung in dem elektronischen Baustein 9 der Schloßsteuerung 3 noch ein Zähler- und Zeitschalter 14 vorgesehen sein kann, welcher zum einen bewirken kann, daß er bei fehlendem oder falschem Antwortcodesignal 22 vom Datenauswerter 13 aktiviert wird und das Schaltsignal zur erneuten Abgabe von Fragecode 19 aus dem Speicher 11 nur mit erheblicher Verzögerung weitergibt und zum anderen bewirken kann, daß er bei häufigen öffnungscodesignalempfängen innerhalb einer kurzen Zeiteinheit aktiviert wird t>o und seinerseits ein Verweigerungsglied 15 aktiviert, welches die Abgabe von Fragecode 19 verhindert. Ein aktiviertes Verweigerungsglied 15 gestattet es auch dem Eigentümer nicht mehr, über den normalen Dialog das Schloß zu entriegeln. Es ist für ihn dann ein sicheres Indiz dafür, daß von Unbefugten versucht wurde, die Tür zu öffnen. Um jedoch den Eigentümer in die Lage zu versetzen, über den normalen Dialog die Tür wieder öffnen zu können, ist in dem Speicher 5 des elektronischen Schlüssels 2 ein zusätzlicher Code gespeichert, welcher durch eine besondere Taste am Sender 4 als separates Enlsperrcodesignal 24 ausgesendet und unmittelbar am Empfänger 10 der Schloßsteuerung 3 abgegeben zu einer Inaktivierung des Verweigerungsgliedes 15 führt.An unauthorized person now has the entire dialogue between electronic key 2 and lock control 3 recorded, i.e. the signals 18, 20 and 22, the use of this recording nevertheless does not lead to Generation of the signal 23 for unlocking the lock 17, since every time the opening code signal 18 is emitted another random code signal 20 and response code signal 22 is generated. Even a multiple use of the recorded Dialogue by the unauthorized person does not lead to a random generation of the signal 23, since in a further embodiment of the subject matter of the invention as a further safety precaution in the electronic Module 9 of the lock control 3 can also be provided with a counter and timer switch 14, which On the one hand, it can have the effect that, if the response code signal 22 is missing or incorrect, from the data evaluator 13 is activated and the switching signal for the renewed delivery of question code 19 from the memory 11 only with considerable Delay passes and on the other hand can cause it with frequent opening code signal receipts activated within a short period of time t> o and in turn activates a denial element 15, which prevents the issue of question code 19. A Activated denial element 15 also no longer allows the owner to use the normal dialog to unlock the lock. For him it is a sure sign that unauthorized persons have tried to do this Door open. However, in order to enable the owner to open the door again via the normal dialog to be able to open, an additional code is stored in the memory 5 of the electronic key 2, which is sent out by a special button on the transmitter 4 as a separate unlock code signal 24 and immediately delivered to the receiver 10 of the lock control 3 to inactivate the refusal member 15 leads.
