Abstract

A device initialization method includes generating a license request for a personal media device. A timeout indicator may be obtained for a subscription associated with the personal media device. The license request and the timeout indicator may be combined to form a device license for the personal media device. The device license may be digitally-signed to form a signed device license.

Claims

1-18. -18. (canceled)

19. A method of transferring content from a source device to a target device comprising:

receiving a target device license from the target device, the target device license being digitally-signed by a licensing service;

verifying the integrity of the target device license;

establishing a secure communication channel between the source device and the target device; and

transferring at least one media data file from the source device to the target device using the secure communication channel.

20. The method of claim 19 further comprising:

obtaining, from the target device license, a timeout indicator for a subscription associated with the target device.

21. The method of claim 20 further comprising:

comparing the timeout indicator to a system clock to determine if the subscription is valid and current; and

prohibiting the transfer of the at least one media data file if it is determined that the subscription is not valid and current.

22. The method of claim 19 further comprising:

receiving a target device digital certificate from the target device; and

verifying the integrity of the target device digital certificate.

23. The method of claim 19 further comprising:

receiving a source device digital certificate from the source device; and

verifying the integrity of the source device digital certificate.

24. The method of claim 19 wherein the target device license includes a least one of:

a user ID that identifies a subscription associated with the target device;

a challenge;

a target device digital certificate;

a licensing service digital certificate;

a system time indicator;

a user encryption key; and

a timeout indicator for the subscription.

25. The method of claim 24 wherein transferring at least one media data file includes:

unbinding the at least one media data file from a user of the source device to generate at least one unbound media data file;

transferring the at least one unbound media data file from the source device to the target device using the secure communication channel; and

binding the at least one unbound media data file to a user of the target device using the user encryption key.

26. The method of claim 25 wherein binding the at least one unbound media data to a user of the target device includes:

encrypting a content encryption key for the at least one unbound media data file using the user encryption key.

27. The method of claim 19 wherein the secure communication channel is a wireless communication channel.

28. The method of claim 19 wherein the secure communication channel is a wired communication channel.

29. The method of claim 19 wherein establishing a secure communication channel includes:

generating a random session key on a first of the source device and the target device; and

providing the random session key to the other of the source device and the target device.
