Abstract

A method and system of enabling slave software applications from a portable device via a vehicle interface system. The vehicle includes a first communication channel for exchanging data communications between the portable device and the vehicle interface system and a second communication channel configured to transmit video to the vehicle interface system. A mutual authentication is performed between the portable device and the vehicle interface system using the first communication channel based on identifying the portable device as an entity authorized to execute approved slave software applications. The portable device is authenticated over the second communication channel for verifying that the portable device is the authorized entity to transmit video over the second communication channel. The video is transmitted to the vehicle interface system over the second communication channel conditioned upon a successful authentication of the portable device over the second communication channel.

Claims

1. A method for enabling slave software applications from a portable device via a vehicle interface system, the portable device having at least one executable slave software application, the vehicle including a first communication channel for exchanging data communications between the portable device and the vehicle interface system, the vehicle including a second communication channel configured to transmit video to the vehicle interface system, the method comprising the steps of:

performing a mutual authentication between the portable device and the vehicle interface system using the first communication channel based on the vehicle interface system identifying the portable device as an entity authorized to execute approved slave software applications via the vehicle interface device;

initiating communication over the second communication channel by one of the portable communication device or vehicle system interface for transmitting video from the portable device to the vehicle interface system, the video including a graphical user interface for controlling the slave software applications;

authenticating the portable device over the second communication channel for verifying that the portable device is authorized to transmit the video over the second communication channel; and

transmitting the video to the vehicle interface system over the second communication channel conditioned upon a successful authentication of the portable device over the second communication channel.

3. The method of claim 1 wherein after initiating video transmission over the second communication channel, the vehicle interface system transmits an authentication query at various time intervals over the second communication channel for verifying that a respective device transmitting the video is authorized to transmit video over the second communication channel.

4. The method of claim 1 wherein after an initiating video transmission over the second communication channel, the portable device repeatedly transmits authentication credentials at various time intervals for verifying that the portable device is authorized to transmit video over the second communication channel.

5. The method of claim 1 wherein mutual authentication is initiated by the portable device.

6. The method of claim 1 wherein mutual authentication is initiated by the vehicle interface system.

7. The method of claim 1 wherein authenticating the portable device to the vehicle interface system over the second communication channel comprises the steps of:

the vehicle interface system transmitting a code to the portable device over the first communication channel;

the portable device receiving the code transmitted by the vehicle interface system;

the portable device transmitting the code to the vehicle interface system over the second communication channel; and

establishing authenticity of the portable device in response to the vehicle interface system determining the code received over the second communication channel is valid.

8. The method of claim 7 wherein the code is encrypted.

9. The method of claim 1 wherein authenticating the portable device to the vehicle interface system over the second communication channel comprises the steps of:

the portable device transmitting a certificate to the vehicle interface system over the second communication channel in response to a successful mutual authentication between the portable device and the vehicle interface system;

the vehicle interface system receiving the certificate transmitted over the second communication channel; and

establishing authenticity of the portable device in response to the vehicle interface system determining the certificate transmitted over the second communication channel is valid.

10. The method of claim 1 wherein the vehicle interface system prevents video from being transmitted over the second communication channel in response to an unsuccessful mutual authentication between the portable device and the vehicle interface system over the first communication channel.

11. The method of claim 10 wherein a message is provided to a user indicating the failed authentication.

12. The method of claim 1 wherein the vehicle interface system prevents video from being transmitted over the second communication channel in response to an unsuccessful authentication of the portable device to the vehicle interface system over the second communication channel.

13. The method of claim 12 wherein a message is provided a user indicating the failed authentication.

14. The method of claim 1 wherein the second communication channel includes a LAN communication channel for transmitting video.

15. The method of claim 14 wherein the second communication channel includes a wireless communication channel for transmitting video.

2. The method of claim 2 wherein the vehicle interface device includes a human machine interface having a display screen for displaying the video, the human machine interface accepting a manual input by a user and presenting application content to the user for controlling the slave application software.

16. A portable device-to-vehicle interface system comprising:

a portable device including executable slave software applications;

a vehicle interface system including a human machine interface for displaying video having a graphical user interface for execution and control of slave software applications stored on the portable device, the video displayed on the human machine interface being transmitted from the portable device;

a first communication channel for exchanging data communications between the portable device and the vehicle interface system; and

a second communication channel configured to transmit video from the portable device to the vehicle interface system;

wherein a mutual authentication between the portable device and the vehicle interface system is performed over the first communication channel, wherein the portable device is identified as an entity authorized to execute slave software applications via the vehicle interface device, wherein communication over the second communication channel for transmitting video over the second communication channel is initiated by one of the portable communication device or vehicle system interface, wherein the portable device is authenticated over the second communication channel for verifying that the portable device is the authorized entity transmitting the video over the second communication channel, wherein the portable device transmits video of an approved slave software application to the vehicle interface system over the second communication channel conditioned upon a successful authentication of the portable device over the second communication channel.

17. The portable device-to-vehicle interface system of claim 16 wherein the human machine interface device includes a display screen for viewing the slave software applications, wherein the graphical user interface is displayed on the display screen for controlling the slave software application.

18. The portable device-to-vehicle interface system of claim 16 wherein the vehicle interface system prevents video from being transmitted over the second communication channel in response to an unsuccessful authentication of the portable device over the second communication channel.

19. The portable device-to-vehicle interface system of claim 16 wherein the second communication channel includes a LAN communication channel.

20. The portable device-to-vehicle interface system of claim 16 wherein the second communication channel includes a wireless communication channel.
