Im Universellen Schlüssel UnivKeyl und/oder Mobilfunkendgerät MSI kann z.B. das (dort beim Anlernen und/oder später erhaltene) gespeicherte weitere Geheimnis Geheimn-anlern-Kfzl z.B. sofort oder nach einer vorgegebenen (z.B. mit einem Timer TimUKl im Universellen Schlüssel UnivKey 1 und/oder einem Timer im Mobilfunkendgerät MSI und/oder Kfzl und/oder Server Serv etc. kontrollierten) Zeit automatisch gelöscht werden. In the universal key UnivKeyl and / or mobile terminal MSI, for example, the (there when learning and / or received later) stored further secret secret learning Kfzl eg immediately or after a predetermined (eg with a timer TimUKl in the universal key UnivKey 1 and / or a timer in the portable radio terminal MSI and / or Kfzl and / or server Serv etc. controlled) time automatically be deleted ,
Ein solcher Anlernvorgang des Universellen Schlüssel UnivKeyl an das Kraftfahrzeug Kfzl kann beispielsweise mit diesem selben (UnivKeyl) oder einem (oder mehreren) anderen (UnivKey2) Universellen Schlüssel für mehrere nicht dargestellte Kraft¬ fahrzeuge Kfz2 usw. erfolgen, z.B. auch für eine Fahrzeugflotte. Damit ist bzw. sind (nach Löschung im zum Anlernen la-lf verwendeten Universellen Schlüssel) ein oder mehrere Kraftfahrzeuge Kfzl, Kfz2 usw. (nur noch) an einen Server Serv angelernt, also mit einem (z.B. nur) dort (Serv) gespeicherten weiteren Geheimnis Geheimn-anlern-Kfzl startbar und/oder offenbar und/oder verschließbar und/oder nur am Kofferraum verschließbar etc. Nun kann also, wie Fig. 2 zeigt, ein beliebiger der universellen Schlüssel Univkeyl, UnivKey2 (z.B. auch von einem beliebigen Benutzer Benl , Ben2) vom Server Serv (mit z.B. (Funk) -Übertragung eines zu einem Kraftfahrzeug Kfzl (z.B. mit dessen Identität ID-Kfz-1) und/oder Mobilfunkendgerät und/oder Benutzer Benl und/oder Code Pinl jeweils gespeicherten weiteren Geheimnisses Geheimn-anlern-Kfzl an den Universellen Schlüssel) autorisiert werden, eines (Kfzl) oder mehrere der Kraftfahrzeuge mit einem weiteren Geheimnis Geheimn-anlern-Kfzl zu starten und/oder öffnen und/oder verschließen und/oder nur am Kofferraum zu verschließen etc. Such a learning process of the universal key UnivKeyl to the motor vehicle Kfzl can be done, for example, with this same (UnivKeyl) or one (or more) other (UnivKey2) Universal key for several not shown Kraft ¬ vehicles Kfz2, etc., for example, for a vehicle fleet. Thus, one or more vehicles Kfzl, Kfz2 etc. (after deletion in the used for learning la-lf Universal Key) (only) trained to a server Serv, so with a (eg only) there (Serv) stored further Secret Seek-learning-Kfzl bootable and / or apparent and / or closed and / or lockable only at the trunk etc. Now, as shown in FIG. 2, any of the universal key Univkeyl, UnivKey2 (eg, also by any user Benl , Ben2) from the server Serv (with eg (radio) transmission of a further secret secret stored on a motor vehicle Kfzl (eg with its identity ID-Kfz-1) and / or mobile terminal and / or user Benl and / or Code Pinl Anlern-Kfzl to the universal key) are authorized to start one (car) or more of the cars with another secret secret learning carl and / or open and / or close and / or only on the trunk to verse close etc.
Fig. 2 zeigt ein Autorisieren eines universellen Schlüssels UnivKeyl durch einen Server Serv dazu, dass dieser universelle Schlüssel UnivKeyl nach diesem Autorisieren ein Kraftfahrzeug Kfzl mit einem (z.B. für dieses in Form von dessen Identität ID-Kfz-1 etc. auffindbaren) im Server Serv gespeicherten weiteren Geheimnisses Geheimn-anlern-Kfzl starten und/oder öffnen und/oder verschließen und/oder nur am Kofferraum verschließen etc. kann. Fig. 2 shows an authorization of a universal key UnivKeyl by a server Serv that this universal key UnivKeyl after this authorizing a motor vehicle Kfzl with a (eg for this in the form of its identity ID-Kfz-1 etc. findable) in the server Serv stored secrets secret-learning Kfzl start and / or open and / or close and / or close only at the trunk, etc. can.

Der Server Serv prüft ggf. die Mobilfunkendgerät MSI identi¬ fizierende Angabe MS1-ID (wie z.B. eine MSISDN etc . ) und/oderdie den Benutzer Ben 1 des Mobilfunkendgeräts MSI identifizierende Angabe PINl und/oder die das Kraftfahrzeug Kfzl identifizierende Angabe ID-Kfz-1 anhand in einem angedeuteten Speicher Spei-Serv gespeicherte Werte, In FIG. 2, as a first step 2a, a mobile terminal MSI (such as a mobile phone, tablet, computer, etc.) transmits, eg under the control of a software or application app, via a mobile radio interface Mobi (such as 2G, 3G, 3.5G, 4G etc.) one the mobile station MSI identifying indication MS1 ID (such as an MSISDN, etc.) and / or the user Ben 1 of the mobile station MSI identifying indication pinl (such as a user Benl before the mobile station by Tasta ¬ ture / language etc. entered input) and / or one and / or a the motor vehicle Kfzl identifying information ID-Kfz-1 and / or a request Anf-Key (for another secret secret-learning serv-1 as a virtual key to open / Closing / starting / etc. Of a specific motor vehicle) to a server Serv connected to the mobile radio network Mobi. The server SERV verifies if necessary, the mobile station MSI identi ¬ fizierende indication MS1 ID (such as etc a MSISDN.) And / or the user Ben 1 of the mobile station MSI identifies indication Pinl and / or the motor vehicle Kfzl identifying indication ID automotive 1 using values stored in an indicated memory Spei-Serv,
und/oder identifiziert z.B. nach erfolgreichem Prüfen (z.B. anhand erhaltener MS1-ID und/oder Ben 1 und/oder ID-Kfz-1) das weitere Geheimnis Geheimn-anlern-serv-1 zum Öffnen/Schließen/Starten etc. eines bestimmten Kraftfahrzeugs Kfzl in seinem Speicher Spei-Serv. and / or identifies e.g. after successful testing (eg based on obtained MS1-ID and / or Ben 1 and / or ID-Kfz-1) the further secret secret-learning-serv-1 for opening / closing / starting etc. of a certain motor vehicle Kfzl in its memory Spei -serv.
In Fig. 2 überträgt im Schritt 2b der Server Serv ein (z.B. anhand erhaltener MS1-ID und/oder Ben 1 und/oder ID-Kfz-1) identifiziertes weiteres Geheimnis Geheimn-anlern-Kfz-1 zum Öffnen etc. eines bestimmten Kraftfahrzeugs Kfzl an das (hiernach anfragende) Mobilfunkendgerät MSI z.B. über eine Mobilfunk¬ schnittstelle Mobi. In Fig. 2 überträgt im Schritt 2c das Mobilfunkendgerät MSI über eine (z.B. Bluetooth) Schnittstelle Bluet-MSK->UnivKeyl an den (z.B. mit dem Mobilfunkendgerät gerade per Bluetooth verbundenen) universellen Schlüssel UnivKeyl das weitere Geheimnis Geheimn-anlern-Kfzl (für das Kfzl), welches der universelle Schlüssel UnivKeyl in einem angedeuteten Speicher Spei-UnivKeyl speichert (z.B. nur für eine ihm vorgegebene Zeit tl) . In Fig. 2, in step 2b, the server Serv transmits a secret (eg, obtained from the obtained MS1-ID and / or Ben1 and / or ID-car-1) of the secret-learning vehicle-1 for opening, etc., a particular motor vehicle Car to the (hereafter requesting) mobile terminal MSI eg via a mobile interface ¬ Mobi. In Fig. 2 transmits in step 2c, the mobile station MSI via a (eg Bluetooth) interface Bluet-MSK-> UnivKeyl to the (for example, with the mobile device just connected via Bluetooth) universal key UnivKeyl the other secret secret learning Kfzl (for the Kfzl), which stores the universal key UnivKeyl in an indicated memory Spei-UnivKeyl (eg only for a given time tl).
In Fig. 2 im Schritt 2d überträgt (z.B. zum Öffnen oder Schließen oder Starten etc.) der universelle Schlüssel UnivKeyl über eine (z.B. Bluetooth) Schnittstelle Bluet-UnivKeyl<->Kfzl an eine Funkschnittstelle BluetKfz des Kraftfahrzeugs Kfzl das weitere Geheimnis Geheimn-anlern-Kfzl , welche das Kraftfahrzeug Kfzl ggf. z.B. anhand eines in einem angedeuteten Speicher Spei-Kfzl gespeicherten weiteren Geheimnisses Geheimn-anlern-Kfzl vergleicht und/oder überprüft, worauf z.B. bei Übereinstimmung dann von einer KFz-Steuerung KfzContr über eine (CAN etc.) Schnittstelle CAN ein Türöffner Türöff oder Starter MotStart etc. des Kraftfahrzeugs Kfzl (öffnend oder schließend oder startend etc. ) betätigt wird (je nachdem was der universelle Schlüssel fordert, wie z.B. Tür-auf zum Öffnen) . Das weitere Geheimnis Geheimn-anlern-Kfzl kann also (jeweils) als ein virtueller Schlüssel für (z.B. nur genau) ein Kraftfahrzeug Kfz 1 dienen. In Fig. 2 in step 2d transmits (eg for opening or closing or starting, etc.) of the universal key UnivKeyl via a (eg Bluetooth) interface Bluet-UnivKeyl <-> Kfzl to a radio interface BluetKfz of the motor vehicle Kfz the secret secret secrets -Kfzl, which the motor vehicle Kfzl if necessary, for example comparing and / or checking secret learning vehicles with the aid of a further secret stored in an indicated memory Spei-Kfzl, whereupon e.g. in agreement then by a KfzControl KfzContr over a (CAN etc.) interface CAN a door opener door starter or MotStart etc. of the motor vehicle Kfzl (opening or closing or starting etc.) is operated (depending on what the universal key demands, such eg door-to-open). The further secret secret learning vehicle can thus serve (in each case) as a virtual key for (for example only exactly) a motor vehicle motor vehicle 1.
Die Zeitdauer, für welche ein weiteres Geheimnis Ge¬ heimn-anlern-Kfzl (z.B. genau) einen Universellen Schlüssel UnivKeyl dazu berechtigen soll, über z.B. eine Schnittstelle Bluet-UnivKeyl<->Kfzl (z.B. Bluetooth oder andere Funk- schnittsteile wie z.B. PACE, RKE etc.) ein Kraftfahrzeugs Kfzl zu einem Öffnen oder Schließen oder Starten etc. zu veranlassen, kann begrenzt sein, z.B. indem (z.B. im Schritt 2b und/oder 2c) mit dem weiteren Geheimnis Geheimn-anlern-Kfzl an einen universellen Schlüssel UnivKeyl eine Zeitangabe tl gesandt wird, die z.B. im universellen Schlüssel UnivKeyl und/oder Kraftfahrzeug Kfzl z.B. laufend mit einem Zeitgeber TimrUKl verglichen wird, wobei der Universelle Schlüssel UnivKeyl nur bis zum Zeitablauf ein Kraftfahrzeugs Kfzl zum Öffnen oder Schließen oder Starten etc. zu veranlassen bereit ist, und danach nicht mehr . Das weitere Geheimnis Geheimn-anlern-Kfzl kann im Universellen Schlüssel z.B. bei einem festgestellten Manipulationsversuch wie einem Anhalten des Zeitgebers TimerUKl (z.B. auch wenn dieser mittels des Servers und/oder Mobilfunkendgerätes überwacht wird) au¬ tomatisch gelöscht werden. The length of time for which another secret Ge ¬ to home country-anlern-Kfzl to authorize a universal key UnivKeyl to (eg exactly), for example via an interface Bluet-UnivKeyl <-> Kfzl (eg Bluetooth or other radio cut parts such as PACE, RKE etc.) to cause a motor vehicle to open or close or start etc. may be limited, eg by (eg in step 2b and / or 2c) with the further secret secret learning vehicle to a universal key UnivKeyl Time tl is sent, for example, in the universal key UnivKeyl and / or motor vehicle Kfzl eg continuously compared with a timer TimrUKl, the universal key UnivKeyl only until the time of a motor vehicle Kfzl to open or close or start etc., and then nothing more. Further secret-Geheimn anlern-Kfzl can in Universal key for example in a detected tampering attempt, such as a stopping of the timer TimerUKl (for example, even when it is monitored by the server and / or mobile radio terminal) will be deleted ¬ au tomatically.
Eine oder mehrere oder alle Übertragungen (z.B. la-lg, 2a-2d usw.) von Daten können insbesondere kryptografisch gesichert erfolgen. One or more or all of the transmissions (e.g., la-lg, 2a-2d, etc.) of data may in particular be cryptographically secured.
In einer vorteilhaften Ausgestaltung kann ein universeller Schlüssel UnivKeyl jeweils mehrere Protokolle Anlernprot und/oder (weitere) Geheimnisse Geheimn-Anlern-Kfz-1 , Ge- heimn-Anlern-Kfz-2 etc. gleichzeitig verwalten. In einer weiteren Ausgestaltung können pro Fahrzeug mehrere Universelle Schlüssel UnivKeyl, UnivKey2 gleichzeitig angelernt werden und verwaltet werden, z.B. um mehreren Nutzern Benl, Ben2 einen gleichzeitigen Betrieb und/oder Zugang zu erlauben. In einer weiteren Ausgestaltung kann ein Universeller Schlüssel eingeschränkte Rechte verwalten, wie z.B. nur einen Fahrzeugzugang, nur einen Zugang ohne Kofferraumzugang, nur einen Kofferraumzugang etc. In einer weiteren Ausgestaltung wird ein virtueller Schlüssel wie Geheimn-Anlern-Kfz-1 , Ge- heimn-Anlern-Kfz-2 auf dem Server Serv unmittelbar an Fahrzeuge oder andere Zugangsberechtigungen angelernt und der gewöhnliche Anlernvorgang kann entfallen. In an advantageous embodiment, a universal key UnivKeyl can simultaneously manage a plurality of protocols of learning protocol and / or (further) secrets of secret learning vehicle 1, secret learning vehicle 2, etc., at the same time. In a further embodiment, several universal keys UnivKeyl, UnivKey2 can be trained and managed simultaneously per vehicle, e.g. to allow multiple users Benl, Ben2 simultaneous operation and / or access. In a further embodiment, a universal key may manage restricted rights, such as e.g. only a vehicle access, only one access without trunk access, only a trunk access, etc. In a further embodiment, a virtual key such as secret-Anlern-Kfz-1, home-Anlern-Kfz-2 on the server Serv directly to vehicles or others Access rights learned and the usual learning process can be omitted.
Indem man einem Nutzer Benl einen universellen Schlüssel UnivKeyl überlässt, der sich sowohl mit den (meisten) Fahrzeugen Kfzl, Kfz2 als auch über sein Mobilfunkendgerät wie z.B. ein Smartphone (oder direkt) mit einem Server Serv verbinden kann, und der außerdem virtuelle Schlüssel (wie Geheimn-Anlern-Kfz-1 , Geheimn-Anlern-Kfz-2 ) simulieren kann und diesen eine Verfallszeit (tl) zuordnen kann, können ggf. einige oder mehrere oder alle weiteren Zusatzelektroniken entfallen, welche sonst zudem meist noch spezifisch für Fahrzeugreihen ausgeführt werden würden. Durch erfindungsgemäße Ausgestaltungen kann es möglich sein, ein Kraftfahrzeug nicht oder wenig zu verändern bzw. Sicherheitsmechanismen eines Fahrzeugs nicht oder schwer umgehbar zu gestalten. Im weitesten Sinne können Komfortfunktionen des Fahrzeugzugangs und/oder Starts erhalten bleiben (z.B. ein Zugang über Funk, Passive-Entry (Passiver Zutritt) and Pas- sive-Go ( Passiver Start)). By leaving to a user Benl a universal key UnivKeyl, which can connect both with the (most) vehicles Kfzl, Kfz2 as well as via his mobile terminal such as a smartphone (or directly) with a server Serv, and also virtual keys (such Secret-Anlern-Kfz-1, Secret Anlern-Kfz-2) can simulate and this an expiration time (tl) can assign, may account for some or more or all other additional electronics, which are usually also usually still running specifically for vehicle series would. By embodiments according to the invention, it may be possible to modify a motor vehicle little or not or to make security mechanisms of a vehicle or difficult to bypass. In the broadest sense, comfort functions of vehicle access and / or take-off can be retained (eg access via radio, passive entry and passive go).
