Abstract

A mobile device may be associated with a vehicle for verification of software updates. The mobile device may be configured to receive a message including an encryption key with which a software update for the vehicle is encrypted, provide a user interface requesting user verification of installation of the software update, and responsive to receipt of the user verification, provide the encryption key to the vehicle to allow the vehicle to decrypt the software update. An update server may be configured to send a software update encrypted using an encryption key to a vehicle, receive a request from the vehicle requesting that the encryption key used to encrypt the software update be provided to a mobile device associated with the vehicle for verification of software updates, and send the encryption key to the mobile device responsive to the request.

Claims

1. A system comprising:

a mobile device, associated with a vehicle for verification of software updates, programmed to

responsive to receipt of an encryption key with which a software update downloaded to the vehicle is encrypted and decryption of the software update by the vehicle using an additional decryption key, display a user interface requesting user verification of installation of the software update; and

responsive to receipt of the user verification, provide the encryption key to the vehicle to allow the vehicle to further decrypt the software update for installation.

2. The system of claim 1, wherein the mobile device is further configured to:

present a user interface requesting confirmation that the vehicle and the mobile device should be associated for verification of software updates, and

responsive to receipt of confirmation of the association from the user interface, provide an indication to the vehicle that the mobile device is associated with the vehicle for verification of software updates.

3. The system of claim 1, wherein the software update is received by the vehicle from an update server, and the encryption key is a symmetric key with which the update server encrypted the software update.

4. The system of claim 3, wherein the encryption key is received by short message service (SMS) message from the update server.

5. A method for a mobile device, comprising:

responsive to receiving an encryption key with which a software update downloaded to a vehicle is encrypted and decrypting the software update by the vehicle using an additional decryption key, displaying a user interface requesting user verification for installing the software update; and

responsive to receiving the user verification, providing the encryption key to the vehicle allowing the vehicle to further decrypt the software update for installation.

6. The method of claim 5, further comprising:

presenting a user interface requesting confirmation that the vehicle and the mobile device should be associated for verification of software updates; and

responsive to receipt of confirmation of the association from the user interface, providing an indication to the vehicle that the mobile device is associated with the vehicle for verification of software updates.

7. The method of claim 5, wherein the software update is received by the vehicle from an update server, and the encryption key is a symmetric key with which the update server encrypted the software update.

8. The method of claim 7, wherein the encryption key is received by short message service (SMS) message from the update server.

9. A non-transitory computer-readable medium comprising instructions that, when executed by a processor of a mobile device, cause the processor to:

responsive to receipt of an encryption key with which a software update downloaded to a vehicle is encrypted and decryption of the software update by the vehicle using an additional decryption key, display a user interface requesting user verification of installation of the software update; and

responsive to receipt of the user verification, provide the encryption key to the vehicle to allow the vehicle to further decrypt the software update for installation.

10. The medium of claim 9, further comprising instructions to cause the processor to:

present a user interface requesting confirmation that the vehicle and the mobile device should be associated for verification of software updates; and

responsive to receipt of confirmation of the association from the user interface, provide an indication to the vehicle that the mobile device is associated with the vehicle for verification of software updates.

11. The medium of claim 9, wherein the software update is received by the vehicle from an update server, and the encryption key is a symmetric key with which the update server encrypted the software update.

12. The medium of claim 11, wherein the encryption key is received by short message service (SMS) message from the update server.
