Definitions
- the invention relates to a device for testing the Use authorization for access control devices, in particular closing devices for vehicles, with an access-side control device with a Memory area for a secret code, one user-side key device having a Transponder with a memory area for storing a contains secret codes, and comparison means in the Control device for determining the release the access device required authorization, such that the information emitted by the transponder with a in the control by the secret Code specified specification information is compared and that only with a match a release of the Access is made, the transponder of the Key device a a vehicle-specific Release information of the key device for the Control device having further memory area contains, wherein the control means for Check if the key device has the permission has to be taught to the controller, having.
- Such devices for testing the Use authorization for access control devices the from an access-side control device and a consist of user-side key device known practice.
- Modern key facilities get as central Element a transponder coupled to a chip, which in electromagnetic excitation a User code information, for example in the form of a Number sequence, sends out.
- control device In the control device is then compared, whether the from Transponder emitted in the key device User code information to an authorized user close or not. Only with identification of the authorized user gives the controller the Access to the downstream components of the vehicle free, while in the other case access to the operation of the Vehicle is blocked. To the owner of the respective Key device is to be designated as authorized in a so-called "learning process" of the key device a secret code transmitted by the controller. After teaching the complete vehicle key set, the user when taking over the vehicle has been passed, each key is thus characteristic for the authorized vehicle user.
- each vehicle is equipped with a vehicle identification code.
- spare keys and a transmitter within the vehicle encrypted codes are exchanged and stored in the spare key in a data matrix.
- the replacement key has at least two memory locations in which the vehicle identification code and a decryption function can be stored.
- the instruction code BC is read out and in the presence of a teach-in command with a Sharing routine continued.
- a random number generator generates a random code.
- the Random code is transmitted to the vehicle and there is the code C, which contains the VIN, overwritten. That means that of the workshop stored secret code C after learning in the Key is overwritten and no longer exists is.
- US 5,369,706 relates to a method for releasing an access control device by means of rolling Codes.
- rolling codes will look like Hash tables are taken from secret codes that are unique Activation of an access control device entitle. After that, that is after one-time Unlock, a new code is detected.
- These rolling codes are both in the lock as well as stored in the key. Therefore, when in the Key the next code is detected, this one also in the Lock detected. Since the hash tables are not from the outside is therefore a secure access control possible.
- the invention is based on the object Device of the type mentioned to that effect to develop an automatic learning of a or spare key by the user himself simultaneous protection against abuse.
- the device according to the invention offers a large Safety when teaching new key devices a control unit, there by checking a vehicle-specific release information in the additional storage area of a new one Key device is ensured that a new Key device only from the controller of a certain vehicle can be taught by the one for which it has the release information. there the authorization for teaching is checked by the already existing in the control device Comparative means used by the key facility received release information with a required Compare release information.
- the drawing gives an overview of the use of the invention provided additional Memory area in the key facility for the Storing a release information that is suitable for learning a new key device should be required.
- a Key device B of the device according to the invention shown comprises a Transponder with a transponder coil T and a first Memory area SP1 for the secret code for a usual access authorization procedure is provided.
- a second memory area SP2 available. In both memory areas SP1 and SP2 are no information stored at this time.
- a device C of a spare parts center contains, among other things, a database or has access to such.
- the database contains memory areas SC 1 -SC n , in which vehicle-specific information is stored by all vehicles for which this spare parts center is responsible.
- vehicle-specific information is stored by all vehicles for which this spare parts center is responsible.
- it is assumed that it is separate secret information.
- also publicly accessible information such as the control unit identification numbers can be stored.
- the spare part center device C also has means (not shown) for transmitting the stored secret data or, in the case of non-secret stored data, means for encrypting and transmitting the data.
- the spare parts center receives from a customer the Request for another key device for a Vehicle.
- the Device C of the spare parts center which stored Information about the vehicle belongs, for which a new one Key facility is requested.
- the device C transmits this or one of them Generated release information M2 to a Key device B, the so far no vehicle is assigned and whose two memory areas SP1 and SP2 does not contain any data yet.
- the key device B stores the received Release information M2 in its additional Memory area SP2.
- the key device B which in the second representation (2) again with the Information M2 occupied memory area SP2 is shown can now from the parts center to the customer be handed over.
- the third representation (3) turn the above described key device B shown. additionally is here indicated by a rectangle a vehicle FZ, at the control unit, the new key device B should be taught.
- This control unit is in the Vehicle FZ marked and marked A.
- the Control unit A has at least one Memory area SP3 in which the secret code for review the user authorization is stored. Furthermore it has a means of comparison V and not over recorded means for transferring data.
- a second memory area SP4 provided in which another secret information is stored. Additionally or alternatively, a Memory area for storing a PIN number to be available.
- the key device B the customer of the Spare parts center was handed out and now over has a secret release information M2 reads it Information from its additional memory area SP2 and transmits them, as indicated by an arrow, to the control unit A of the vehicle FZ.
- the key device B stores the received secret code M1 in the first memory area SP1 of the Transponders as seen in illustration (5).
- the key device B is now to the control unit A of the vehicle FZ taught and can by the user as proof of authorization to use the vehicle be used.
