Description
Die Erfindung bezieht sich auf ein Fahrzeug mit einem Schlüssel, der zur Identifizierung des berechtigten Benutzers eine auslesbare individuelle Kennung enthält.The The invention relates to a vehicle with a key that to identify the authorized user a readable individual identifier contains.
Ein
derartiger Schlüssel
ist im Rahmen der elektronischen Wegfahrsicherung seit einiger Zeit üblich und
auch aus der
Diese Daten sollen aber nicht ohne weiteres zugänglich sein. Wird der Schlüssel verloren, so hätte dies möglicherweise unangenehme Konsequenzen für den Fahrzeugbenutzer, da dann beispielsweise das Fahrzeugkennzeichen und insbesondere seine Anschrift ohne weiteres feststellbar sind. Bringt man die Daten andererseits in dem Bereich unter, der im Rahmen der elektronischen Wegfahrsperre mit Hilfe der individuellen Kennung zugänglich ist bzw. durch diese vor einem unberechtigten Zugriff geschützt ist, so entsteht dadurch eine Sicherheitslücke im System der elektronischen Wegfahrsperre. Bei einem Werkstattaufenthalt würde dann unter Umständen das Kennwort nachvollziehbar sein und damit im ungünstigsten Fall auch einem Unberechtigten bekannt werden können. Auch das Ändern der Daten, beispielsweise bei einem Besitzerwechsel wäre dann nur nach Eingabe der im Rahmen der elektronischen Wegfahrsperre eine zentrale Bedeutung besitzenden individuellen Kennung möglich. Auch hier bestünde die Gefahr einer ungewollten Kenntnisnahme durch Dritte.These But data should not be readily available. If the key is lost, so would have this may be unpleasant consequences for the vehicle user, since then, for example, the vehicle registration and in particular his address can be readily ascertained. On the other hand, if you put the data in the area under the electronic immobilizer using the individual identifier accessible is or is protected by this from unauthorized access, this creates a security hole in the electronic system Immobilizer. In a workshop visit would then possibly the Password be traceable and thus in the worst case, even an unauthorized person can be known. Also changing the data, such as a change of ownership would then only after entering the as part of the electronic immobilizer one central meaning possessed individual identifier possible. Also here would be the Danger of unwanted notice by third parties.
Der Erfindung liegt die Aufgabe zugrunde, ein Fahrzeug der eingangs genannten Art zu schaffen, bei dem die Daten vor einem mißbräuchlichen Zugriff geschützt und dennoch ohne Benutzung der individuellen Kennung änderbar und insbesondere auslesbar sind.Of the Invention is based on the object, a vehicle of the beginning in which the data is protected against misuse protected and yet changeable without using the individual identifier and in particular are readable.
Die Erfindung löst diese Aufgabe durch die Merkmale des Patentanspruchs 1.The Invention solves This object is achieved by the features of patent claim 1.
Die Daten können nunmehr nur gelesen und beschrieben werden, wenn zuvor das Paßwort manuell eingegeben wurde. Dieses Paßwort ist in der Regel lediglich dem Fahrzeugbenutzer bekannt. Es kann sich dabei um eine vierstellige Kenn-Nummer handeln, die bei Codekarten üblich ist.The Data can Now only read and written, if previously the password manually was entered. This password is usually known only to the vehicle user. It can This is a four-digit identification number, which is common in code cards.
Eine verbesserte Sicherheit läßt sich erreichen, wenn es sich bei dem Paßwort um die Fahrgestellnummer des Fahrzeuges handelt. Im Rahmen des Werkstattaufenthalts legt der Kunde in der Regel ohnehin die Fahrzeugzulassungspapiere vor. Diese enthalten die Fahrgestellnummer. Für den Kunden bedeutet es keinerlei Schwierigkeit, die Fahrgestellnummer einzugeben. Gleichzeitig ist der Fahrzeugbenutzer davor geschützt, das Paßwort vergessen oder verwechseln zu können und damit den Zugriff auf die Daten nicht ermöglichen zu können.A improved safety can be reach if the password is the chassis number of the vehicle. As part of the workshop stay lays the customer usually already the vehicle registration papers before. These contain the chassis number. For the customer, it means nothing Difficulty to enter the VIN. At the same time protects the vehicle user from the password forget or confuse and thus not be able to access the data.
Die Prüfung des Paßworts kann mit Hilfe einer zentralen Datenbank vorgenommen werden, in der beispielsweise die Fahrgestellnummern sowie die zugehörigen Grunddaten wie Name und Anschrift des Fahrzeugbesitzers gespeichert sind. Aufbau und Pflege einer derartigen Datenbank sind jedoch besonders aufwendig. Die se Datenbank, die zweckmäßigerweise durch den Hersteller des Fahrzeugs betrieben werden müßte, sollte die Daten sämtlicher Fahrzeuge dieses Herstellers enthalten. Daraus resultieren aber erhebliche Übertragungswege und die Gefahr von Störungen, wenn beispielsweise eine Service-Werkstätte tätig wird, die sich in großer Entfernung vom Hersteller, beispielsweise in einem anderen Kontinent befindet.The exam of the password can be done with the help of a central database in which For example, the chassis numbers and the associated basic data as the name and address of the vehicle owner are stored. construction and maintaining such a database, however, are particularly expensive. The se database, which expediently should be operated by the manufacturer of the vehicle should the data of all vehicles This manufacturer included. However, this results in considerable transmission paths and the danger of disturbances, when, for example, a service workshop becomes active, which is at a great distance from the manufacturer, for example, located in another continent.
Demgegenüber ist es wesentlich einfacher, wenn das Paßwort in dem Lesegerät selbst entsprechend einem vorgegeben Algorithmus umgeschlüsselt wird. Das Lesegerät stellt dann den Zugang zu den Daten her, wenn das umgeschlüsselte Paßwort mit einem identischen Kennwort übereinstimmt, das im Schlüssel enthalten ist. Der Verlust des Schlüssel ermöglicht dann zwar das Auslesen des umgeschlüsselten Kennworts. Um den Zugang zu den Daten zu öffnen, muß aber nicht dieses Kennwort, sondern das mit diesem über den vorgegebenen Algorithmus verbundene Paßwort an das Lesegerät übertragen werden. Da der Algorithmus in der Regel nicht bekannt ist, läßt sich somit aus der Kenntnis des Kennworts nicht das zugrundeliegende Paßwort ermitteln. Damit ist auch bei einem Verlust des Schlüssels eine Sicherheit vor einer ungewollten Bekanntgabe der benutzerindividuellen Daten gewährleistet.In contrast, is It is much easier if the password in the reader itself is recoded according to a given algorithm. The reader then establishes access to the data if the encrypted password with matches an identical password, that in the key is included. The loss of the key then allows the readout of the recast Password. However, to open access to the data, you do not have to enter this password, but with this over transfer the password associated with the given algorithm to the reader become. Since the algorithm is usually not known, can be thus from the knowledge of the password not the underlying Password determine. Thus, even with a loss of the key one Security against an unwanted announcement of the user-specific Data guaranteed.
Da aufgrund des Algorithmus eine Sicherheit vor der Bekanntgabe der Daten im Falle eines Schlüsselverlusts besteht, ist es ohne weiteres möglich, das Kennwort frei lesbar im Schlüssel zu speichern. Im Lesegerät ist es dann ohne weiteres möglich, das Kennwort auszulesen, dieses mit dem manuell eingebenen Kennwort zu vergleichen und bei Übereinstimmung der beiden Kennworte für das Lesegerät den Zugang zu den Daten zu ermöglichen.Since the algorithm provides security against the disclosure of data in the event of a key loss, it is readily possible to save the password in the key. In the reader, it is then readily possible to read the password, to compare this with the manually entered password and to allow access to the data in accordance with the two passwords for the reader.
Um einen weiteren Schutz vor einer ungewollten Bekanntgabe der Daten zu erreichen, besteht eine weitere Verbesserung darin, diese Daten erst dann zur Anzeige zu bringen, wenn vorbereitend ein weiteres Authentisierungsmerkmal manuell eingegeben wird. Dabei kann es sich um ein Datum handeln, das in diesen Daten enthalten ist. Hierfür bietet sich beispielsweise die Fahrzeugnummer an.Around further protection against unintentional disclosure of the data There is a further improvement in achieving this data only to bring to the display, if another preparatory Authentication feature is entered manually. It can be to trade a date that is contained in this data. For this offers For example, the vehicle number.
Anhand der Zeichnung ist die Erfindung weiter erläutert.Based the drawing, the invention is further explained.
