Abstract

A method for external use of a device having a wireless communication interface by a program of a mobile device. External use is possible only when a key device serving as an authentication token communicates with the program. This increases the security of an entry method for a vehicle.

Claims

1. A method for external use of a device having a wireless communication interface by a program of a mobile device, the method comprising:

detecting when a key device serving as an authentication token communicates with the program of the mobile device; and

enabling the external use of the device only when the key device is communicating with the program of the mobile device.

2. The method of claim 1, wherein the key device is a vehicle key and the device is a vehicle.

3. The method of claim 1, wherein the key device communicates with the mobile device via a short-range wireless link.

4. The method of claim 1, wherein the key device communicates with the device via the program.

5. The method of claim 1, wherein the connection between the key device, the device and/or the mobile device is secured.

6. The method of claim 1, wherein the connection between the key device, the device and/or the mobile device is secured by an asymmetric encryption method.

7. The method of claim 1, further comprising checking a presence of the key device by a repeatedly performed challenge-response authentication scheme.

8. The method of claim 1, wherein the external use is not initiated and/or is interrupted if there is no communication between the key device and the device and/or between the key device and the mobile device.

9. The method of claim 1, wherein the device and the mobile device communicate with one another using a Bluetooth Low Energy protocol.

10. The method of claim 1, wherein the external use is enabled only when a dead man function of the key device is activated.

11. An apparatus for external use of a device, wherein a mobile device having a program for external use of the device is provided, wherein the device and the mobile device each have a wireless communication interface configured for communication between device and mobile device, wherein a key device serving as an authentication token is provided, wherein the key device and the mobile device each have a wireless communication interface configured for communication between key device and mobile device and wherein the mobile device and/or the device are configured so that external use is possible only when the key device communicates with the mobile device and/or the device.

12. The apparatus of claim 11, wherein the device is a vehicle.

13. The apparatus of claim 11, wherein the key device comprises a dead man function.
