Abstract

A remote function fob associated with a vehicle is disclosed, the fob for enabling secure communication between the vehicle and a device. The fob may include a transceiver configured for communication with the device. The fob may further include a controller which may be configured to enable secure communication with the device via the transceiver. The controller may be further configured for operation with a code generated using a security protocol, the code to be used in secure communication between the device and the vehicle, the code for transmission to the device via the transceiver.

Claims

1. A remote function fob associated with a vehicle for enabling secure communication between the vehicle and a device, the fob comprising:

a transceiver configured for communication with the device; and

a controller configured to enable secure communication with the device via the transceiver;

wherein the controller is further configured for operation with a code generated using a security protocol, the code to be used in secure communication between the device and the vehicle, the code for transmission to the device via the transceiver.

2. The remote function fob of claim 1 wherein the transceiver comprises a high-frequency transceiver configured for near field communication with the device.

3. The remote function fob of claim 1 wherein the transceiver is configured to enable communication with the device using Bluetooth protocol.

4. The remote function fob of claim 1 wherein the transceiver is configured for communication with the device via a wired connection to the device.

5. The remote function fob of claim 1 wherein the fob is part of a system, the system further comprising a control unit adapted to be mounted in the vehicle, the control unit configured to generate the code using the security protocol.

6. The remote function fob of claim 1 wherein the controller is configured to generate the code using the security protocol.

7. The remote function fob of claim 1 wherein the device comprises a mobile telephone, a personal digital assistant, or a personal computer.

8. The remote function fob of claim 1 wherein the controller is configured to act as an interface for secure communication between the device and the vehicle.

9. The remote function fob of claim 1 wherein the device and the vehicle are configured to communicate using a communication protocol comprising WiFi, Bluetooth, or Dedicated Short Range Communication (DSRC).

10. The remote function fob of claim 1 wherein the device and the vehicle are configured to communicate using a cellular communication protocol.

11. The remote function fob of claim 1 wherein the code to be used in secure communication between the device and the vehicle comprises a rolling code.

12. The remote function fob of claim 1 wherein the security protocol is for generating a code to be used in secure communication between the fob and the vehicle.

13. A method for enabling secure communication between a vehicle and a device using a remote function fob associated with the vehicle, the method comprising:

receiving at the fob a secure communication from the device, the communication from the device comprising a request for a code to be used in secure communication between the device and the vehicle;

generating a code using a security protocol, the code to be used in secure communication between the device and the vehicle; and

transmitting a secure communication from the fob to the device, the communication from the fob comprising the code to be used in secure communication between the device and the vehicle.

14. The method of claim 13 wherein the fob comprises a high-frequency transceiver configured for near field communication between the fob and the device.

15. The method of claim 13 wherein the fob is configured for communication with the device via a wired connection to the device.

16. The method of claim 13 wherein a control unit adapted to be mounted in the vehicle is configured for generating the code using the security protocol.

17. The method of claim 13 wherein the fob is configured for generating the code using the security protocol.

18. The method of claim 13 wherein the fob is configured to act as an interface for secure communication between the device and the vehicle.

19. The method of claim 13 wherein the code to be used in secure communication between the device and the vehicle comprises a rolling code.

20. The method of claim 13 wherein the security protocol is for generating a code to be used in secure communication between the fob and the vehicle.
