Definitions
- the invention relates to a method and a device for access control to a secure location, in particular to a motor vehicle, in which these devices exchange authentication data wirelessly between an electronic key and a base station in an active or a passive communication mode, the base station being activated at the beginning of this authentication process the electronic key sends a call signal and this responds to the call signal with a response signal, and in the active communication mode a security procedure is carried out against a radio link extension, and a device for performing this method.
- the intercepted signal via a radio link change to another attacker who is in the vicinity of the electronic key is located, forwarded and the other attacker then the response signal of the electronic key to the call signal of the base station over the radio link extension back to first attacker and sends back to the base station via this
- the known method provides that the electronic key transmits a signal to the base station, which is converted into spectral data by the base station. The base station then only grants access to the secure location if the Transmission of the authentication data, these spectral data correspond to a spectral signature of the electronic key stored in the base station.
- the signal transmitted by the electronic key has at least two tones with different frequencies f-
- the base station examines the response signal it received from the electronic key in which communication mode this response signal was received, and in that the base station in the event that the response signal of the electronic key was received in the active communication mode , sends a first selection command to the electronic key, which causes the electronic key to carry out the subsequent communication in the active communication mode and, in the event that the response signal of the electronic key was received in the passive communication mode, unites the base station to the electronic key sends a second selection command, which causes the electronic key to carry out the subsequent communication in passive communication mode
- the inventive method advantageously ensures that even in passive communication mode between the electronic key and the base station, a corresponding attack by an unauthorized person can be warded off by the base station being active in the type of communication in which it receives the response signal from the electronic Key receives, reacts If the response signal occurs in the active communication mode, the further authentication procedure is carried out in the active communication mode and a radio link extension can be excluded by the known security procedure.
- the base station receives the response signal of the electronic key in passive communication mode, it prevents until the completion of the Access procedure in an advantageous manner, a communication between the base station and the key via the first, active communication mode. It is therefore not possible for an on gripper performs a radio link extension over a frequency of the active communication mode
- Figure 1 is a schematic diagram of an embodiment of the method.
- FIG. 1 is the starting point of the method described below for access control to a secure location, here to a motor vehicle F.
- a base station 10 is arranged in the motor vehicle F, which wirelessly exchanges authentication data with an electronic key 20 in order to ensure that only the owner of the electronic key 20 can gain access to the secure location.
- the base station 10 sends out a call signal WA for the electronic key 20 in an active, first communication mode when an actuator B, e.g. B. a door handle on the motor vehicle F is operated.
- the electronic key 20 then responds in the active communication mode with a corresponding response signal R, whereby a communication connection running in the active communication mode is established between the electronic key 20 and the base station 10.
- the data transmitted between the electronic key 20 and the base station 10 are determined by a communication protocol which is known per se and is therefore no longer described, which the electronic key 20 and the base station 10 follow and the transmission of authentication data from the electronic key 20 to the Base station 10 includes.
- Access to the secured motor vehicle F is only permitted by the base station 10 if the authentication data transmitted by the electronic key 20 match the authentications stored by the base station 10. It is provided here that the signals emitted by the electronic key 20 and / or by the base station 10 have only a limited range, in order to prevent the base station 10 from granting access to the secured motor vehicle F even when the electronic key is located 20 is not within a defined environment - typically a few meters - of the motor vehicle F.
- Radio link extension V forwards to a second attacker B, who then passes the call signal WA of the base station 10 to the electronic key 20 which is out of the range of the base station 10, forwards the response signal R of the electronic key 20 via the radio link extension V to the first attacker A and forwards it then forwards the response signal R of the electronic key 20 to the base station 10, it is provided that the communication taking place between the electronic key 20 and the base station 10 in the first, active communication mode also has a security procedure which allows such a radio link extension V of the corresponding one To recognize signals WA, R and, if necessary, then to terminate the communication.
- the electronic key 20 transmits an identification signal within the framework of its response signal R generated in response to the call signal WA of the base station 10
- Base station 10 converts into spectral data and only continues the communication with the electronic key 20 if the spectral data received by it matches the spectral signature of the electronic key 20, which is stored in the base station 10, in particular it is provided here that the electronic keys 20 two tones with the frequency f-
- the base station 10 not only evaluates the information content of the signals supplied to it, in particular the response signal R of the key 20, but also examines whether the signals supplied to it by the electronic key 20 are in the first, active communication mode or are received in the second, passive communication mode.
- the base station 10 If the base station 10 receives the response signal R generated by the electronic key 20 in response to a call command WA sent by it in the first, active communication mode, it sends in response to the response signal R of the electronic signal received in the active communication mode Final ice 20 to this a first selection signal S1, which - in addition to the usual functions of a selection signal - causes at least the security-relevant and preferably all further communication between the electronic key 20 and the base station 10 can be carried out in the first, active communication mode and the implementation of the remaining authentication process in the passive communication mode is prevented.
- This has the advantage that a radio link extension V can be detected by the security procedure of the active communication mode and, if necessary, appropriate measures are taken against an attack by a non-authorized person can
- the base station 10 of the motor vehicle F receives the response signal R of the electronic key 20 in the second, passive communication mode, it sends a second selection signal S2 in response to the electronic key 20, which in a corresponding manner causes the communication of the further authentication process is carried out in the second, passive communication mode, and the implementation of the remaining authentication process in the first communication mode is prevented. It is therefore a working in the active communication mode Attackers using radio link extension V are no longer able to use it successfully.
