Abstract
The invention relates to a method (100) for securing a communication between a mobile communication apparatus (10) and a vehicle (5), in particular for authentication at a passive access system of the vehicle (5), wherein the vehicle (5) comprises at least one radio unit (20).
Claims21
1-23. (canceled)
A method for securing a communication between a mobile communication apparatus and a vehicle, wherein the vehicle comprises at least one radio unit, wherein the method comprises the following steps:
- a) performing a transmission for providing at least one indicator specific challenge information from the mobile communication apparatus to the at least one radio unit of the vehicle,
- b) performing a vehicle-side processing of the indicator specific challenge information in order to determine an indicator for the radio unit,
- c) determining an addressing information by the mobile communication apparatus independently of the vehicle-side processing,
- d) initiating a communication based on the addressing information by the mobile communication apparatus,
- e) performing the communication between the mobile communication apparatus and the radio unit if the addressing information matches the determined indicator.
A radio module, comprising:
- a transceiver for receiving a transmission message specific for the indicator specific challenge information from a mobile communication apparatus via radio,
- an electronic processing unit to perform a vehicle-side processing of the indicator specific challenge information to determine an indicator for the radio module,
- wherein the processing unit is designed to set the indicator as an identifier for an addressing of the radio module when communicating with the mobile communication apparatus.
A communication apparatus for authentication at a vehicle, comprising:
- an electronic memory device which has stored at least one key information for authentication of at least one radio unit of the vehicle,
- an electronic processing device, which is electrically connected to the memory device and is designed to cryptographically determine at least one addressing information for addressing the at least one radio unit by means of the at least one key information.
