Abstract

A method and apparatus are provided for a subsidizing service provider entity to personalize a subscriber device to ensure the subscriber device cannot be used in a network of a different service provider entity. As the service provider entity subsidizes the subscriber device, it desires to ensure that subscriber device is personalized such that the subscriber device may operate only in its network and not a network of a different service provider entity. The subscriber device is pre-configured with a plurality of provider-specific and/or unassociated root certificates by the manufacturer of the subscriber device. A communication service is established between the service provider entity and the subscriber device allowing for the mutual authentication of the subscriber device and the service provider entity. After mutual authentication, the service provider entity sends a command to the subscriber device to disable/delete some/all root certificates that are unassociated with the service provider entity.

Claims

1. A method operational on a subscriber device, comprising:

establishing a communication service with a service provider entity;

receiving a command from the service provider entity to disqualify specified root certificates stored in the subscriber device, the specified root certificates unassociated with the service provider entity; and

disqualifying the specified root certificates.

2. The method of claim 1, further comprising:

authenticating the subscriber device with the service provider entity; and

authenticating the service provider entity with the subscriber device.

3. The method of claim 2, wherein the service provider entity is authenticated using a root certificate from among a plurality of pre-configured root certificates in the subscriber device.

4. The method of claim 1, wherein disqualifying the specified root certificates disables the specified root certificates on the subscriber device.

5. The method of claim 4, further comprising:

receiving a second command from the service provider entity to enable the specified root certificates previously disabled.

6. The method of claim 5, wherein a determination to send the second command to the subscriber device is made by the service provider entity.

7. The method of claim 6, wherein the determination is based upon a pre-determined event.

8. The method of claim 7, wherein the pre-determined event is the termination of a service contract between the subscriber device and the service provider entity.

9. The method of claim 1, wherein disqualifying the specified root certificates deletes the specified root certificates from the subscriber device.

10. The method of claim 9, further comprising:

receiving a second command from the service provider entity to replace the specified root certificates previously deleted.

11. The method of claim 10, wherein a determination to send the second command to the subscriber device is made by the service provider entity.

12. The method of claim 11, wherein the determination is based upon a pre-determined event.

13. The method of claim 12, wherein the pre-determined event is the termination of a service contract between the subscriber device and the service provider entity.

14. The method of claim 1, further comprising pre-configuring the subscriber device with a plurality of root certificates.

15. The method of claim 14, wherein the plurality of root certificates are installed on the subscriber device by a manufacturer of the subscriber device.

16. The method of claim 1, further comprising:

determining if the specified root certificates have been successfully disqualified; and

sending an acknowledgement to the service provider entity of success or failure of disqualifying the specified root certificates.

17. The method claim 1, wherein the subscriber device is at least one of a femtocell, a home NodeB, or a wireless device.

18. A computer-readable medium comprising instructions operational in a subscriber device, which when executed by a processor causes the processor to:

establish a communication service with a service provider entity;

receive a command from the service provider entity to disqualify specified root certificates stored in the subscriber device, the specified root certificates unassociated with the service provider entity; and

disqualify the specified root certificates.
