Definitions
- the present invention relates to a keyless access authorization control device with at least two object modules, each comprising a specific object and comprising transmitting / receiving devices, and with one or more identification transmitters, each having at least one microprocessor, with data between the identification transmitter (s) in each case via a bidirectional data communication link (n) and the object modules can be transmitted, which data is encoded by means of a symmetrical encryption method using an encryption algorithm and encryption parameters assigned to the respective object module.
- the invention further relates to an identification transmitter and an object module for such a keyless access authorization control device.
- Keyless access authorization control devices are used where access control using a mechanical key is not desired.
- Such access authorization control devices are used, for example, in motor vehicles and in the home.
- the intended opening of the respective object takes place wirelessly by transmitting an appropriate command together with a coded data record (in short: code) from an identification transmitter carried by a user to a transmitting / receiving device assigned to the desired object. If the object-related transceiver receives the code associated with the object, the code applies the person carrying the identification transmitter as authorized to access, so that certain actuators are then activated to enable access, for example to unlock the motor vehicle.
- coded data record in short: code
- identification transmitters and corresponding access authorization control devices So that when using several keyless access authorization control devices, it is not necessary to carry several identification transmitters, identification transmitters and corresponding access authorization control devices have been developed in which a single identification transmitter can be used for an access authorization control query for several objects, for example the motor vehicle, the house and possibly the work place.
- the transmitted code is composed of a fixed code and an alternating code, both of which are sent together to open a motor vehicle.
- an access authorization control device who are only allowed to open the house, but not the motor vehicle, one or more additional identification transmitters are provided in the context of this access authorization control device, which send only one code - the alternating code.
- data is transmitted between the identification transmitter and the transmitting / receiving devices assigned to the objects via a bidirectional data communication link, the data being transmitted by means of a symmetrical encryption method are encoded.
- the transmitted data are encoded using an encryption algorithm used to implement the symmetrical encryption method using certain encryption parameters, these encryption parameters being assigned to the respective object as a so-called encryption secret.
- a comparison of the encryption parameters between the identification transmitter and the respective object is provided in a so-called learning mode.
- a common characteristic of these previously known devices or identification transmitters is that the use of one and the same encryption algorithm is provided for the access authorization for different objects.
- the resulting low flexibility is particularly disadvantageous for objects that have different life expectancies, such as a motor vehicle and a house.
- the newly added object works with the same encryption algorithm, so that a change of the object module belonging to the remaining object is probably also necessary.
- the conflict when changing one of the objects or when adding another object or identification transmitter is almost inevitable.
- the device according to the invention has a significantly higher flexibility for adapting to changing boundary conditions, since the use of at least two different encryption algorithms is provided from the outset, in a first embodiment in the identification transmitter and in a second embodiment in at least one of the Object modules (preferably those with the longest lifespan, such as a house). That’s it For example, in the first embodiment it is possible to select a different encryption algorithm for the new object module when changing an object in the identification transmitter or, if necessary, to replace an old encryption algorithm with a new one by reprogramming the identification transmitter without the other encryption algorithms implemented in the remaining object modules being added influence.
- the second embodiment is particularly advantageous in the event that, for example, the previous vehicle is replaced by a new one, and at the same time a new identification transmitter replaces the one associated with the old vehicle, the new one
- Identification transmitter works with a different encryption algorithm than the old one.
- the encryption algorithm used by the new identification transmitter in the other object module e.g. that of the house - if already present in the memory element of the same - activated for this identification transmitter, or otherwise stored by reprogramming in place of the old, no longer required encryption algorithm, without influencing other encryption algorithms relating to further identification transmitters.
- FIG. 1 shows a schematic illustration of a keyless access authorization control device according to the invention according to a first embodiment.
- Fig. 2 An alternative to the identification transmitter shown in Fig. 1
- An identification transmitter 10 is used in the context of a keyless access authorization control device to provide a user with access authorization for several objects.
- the identification transmitter 10 shown in FIG. 1 contains the necessary electrical transmission / reception means 13 to enable communication with transmission /
- the data are encoded both in the identification transmitter 10 and in the object modules 1, 2 by microprocessors 11, 6, 7 using a symmetrical encryption method, the identification transmitter 10 and the respective object module 1, 2 being used to encrypt the data the same Use encryption parameters P1, P2. These encryption parameters put that between each
- Identifiers 10 and one of the object modules 1, 2 represent existing encryption secrets.
- a separate set of encryption parameters P1, P2, which differ from one another, is stored in a memory element 12 for each object module 1, 2.
- Each of these sets of encryption parameters P1, P2 can be changed in a known manner in the course of a data exchange between the identification transmitter 10 and the object module 1, 2 using the respective parameter set, in order to prevent the encryption secret from being spied on.
- various encryption algorithms A1, A2,... that are suitable and suitable for carrying out a symmetrical encryption method and are also stored in the memory element 12 of the identification transmitter 10, an encryption algorithm being permanently assigned to each object module 1, 2 the one that is also from the respective object module 1, 2 itself is used.
- the fixed assignment of the encryption algorithm to be used by the identification transmitter in relation to the respective object module takes place, so to speak, when the two devices “get to know each other” through a one-time initialization process.
- the encryption algorithms used by the object modules 1, 2 do not necessarily differ from one another, so it can happen, for example, that several object modules 1, 2, 3, ... use one and the same algorithm - for example, A1 , while only a single object module N uses a different algorithm A2, or similar combinations.
- the decisive factor is that a number of common algorithms A1, A2,... are stored in the identification transmitter 10, which if necessary, for example when a new object module is added from the microprocessor 11 can be called. From the stock on
- Encryption algorithms A1, A2, ... which are located in the memory element 12 of the identification transmitter 10, can also be used to replace individual, unnecessary algorithms with newer ones via a programming interface, without influencing the algorithms still required for other object modules.
- the alternative identification transmitter 10 shown in FIG. 2 differs from that in FIG. 1 in that instead of only one microprocessor 11 the use of two independent microprocessors 11 and 11 ′ is provided, the memory elements 12 and 12 ′ assigned to the microprocessors being shown in FIG these are each directly integrated. Such an integration of a memory element 12 in the microprocessor 11 is of course also possible with the identification transmitter 10 shown in FIG. 1.
- the embodiment shown in FIG. 2 offers the advantage over this that the second microprocessor 11 'with those stored in its memory 12' If necessary, additional algorithms can also be completely exchanged in terms of hardware, so that reprogramming is not necessary even if an algorithm that was not intended to be used until then is to be used.
- the first microprocessor 11 with its memory 12, remains in the identification transmitter 10, so that its function in connection with the object module (s) still used is not influenced by the exchange.
- the first embodiment of the keyless access control device according to the invention described so far is based, so to speak, on a universal identification transmitter that can cooperate with several object modules that use different encryption algorithms
- a second embodiment it is provided that at least one universal object module is present, which in turn has several different object modules Identifiers using encryption algorithms can cooperate.
