Abstract

A system that incorporates the subject disclosure may perform, for example, receive secret information and non-secret information from a secure download application function, provide a request for a first verification to a secure element where the first verification is associated with access to content and/or an application that is accessible via the secure download application function, receive the first verification which is generated by the secure element based on the secret information without providing the secret information to the secure device processor, receive the non-secret information from the secure element, and generate a second verification for the access based on the non-secret information, where the content and/or application is accessible from the secure download application function responsive to the first and second verifications. Other embodiments are disclosed.

Claims

1. A device, comprising:

a secure element having a secure element memory; and

a secure device processor separate from the secure element and in communication therewith, the secure device processor having a secure device processor memory with executable instructions, wherein the secure device processor, responsive to executing the instructions, facilitates performance of operations comprising;

generating a first verification for access by the device to content that is sourced via a source server, wherein the first verification is based on non-secret information, wherein the content is accessed from the source server based on the first verification and a second verification, wherein the second verification is generated by the secure element based on secret information that is stored in the secure element memory without the secure element providing the secret information to the secure device processor, and wherein the secure device processor does not have access to the secret information;

generating consumption information by monitoring the access to the content;

providing the consumption information associated with the access to the content to the secure element, the consumption information indicating that the content has been presented by the device; and

preventing the device from further accessing the content according to access instructions from the secure element, wherein the access instructions are responsive to the consumption information.

2. The device of claim 1, wherein the access instructions are generated by the secure element.

3. The device of claim 1, wherein the secret information and the non-secret information are obtained by the secure element from a remote management server.

4. The device of claim 1, wherein the non-secret information comprises a distribution rule associated with digital rights management for the content.

5. The device of claim 1, further comprising a device processor that is separate from the secure element and the secure device processor, wherein the device processor facilitates wireless communications between the device and the source server.

6. The device of claim 1, wherein the secret information includes a decryption key and an authentication credential.

7. The device of claim 1, wherein the non-secret information includes a user identification, a device identification, digital rights management data, or a combination thereof.

8. The device of claim 7, wherein the access instructions are based at least in part on the digital rights management data.

9. The device of claim 1, wherein the secure element comprises a universal integrated circuit card (UICC).

10. The device of claim 9, wherein the secure device processor obtains the non-secret information via communication with a secure download management function of the UICC.

11. A non-transitory machine-readable medium comprising executable instructions that, when executed by a processing system including a secure device processor, facilitate performance of operations comprising:

generating a first verification for access to content that is sourced via a source server, wherein the first verification is based on non-secret information, wherein the content is accessed from the source server based on the first verification and a second verification, wherein the second verification is generated by a secure element having a secure element memory, the secure element separate from the secure device processor and in communication therewith, the second verification based on secret information that is stored in the secure element memory without the secure element providing the secret information to the secure device processor, and wherein the secure device processor does not have access to the secret information;

generating consumption information by monitoring the access to the content;

providing the consumption information associated with the access to the content to the secure element; and

preventing the secure device processor from further accessing the content according to access instructions from the secure element, wherein the access instructions are responsive to the consumption information.

12. The non-transitory machine-readable medium of claim 11, wherein the secret information and the non-secret information are obtained by the secure element from a remote management server.

13. The non-transitory machine-readable medium of claim 11, wherein the non-secret information comprises a distribution rule associated with digital rights management for the content.

14. The non-transitory machine-readable medium of claim 11, wherein the non-secret information includes a user identification, a device identification, digital rights management data, or a combination thereof.

15. The non-transitory machine-readable medium of claim 14, wherein the access instructions are based at least in part on the digital rights management data.

16. A method comprising:

generating, by a processing system comprising a secure device processor, a first verification for access to content that is sourced via a source server, wherein the first verification is based on non-secret information, wherein the content is accessed from the source server based on the first verification and a second verification, wherein the second verification is generated by a secure element having a secure element memory, the secure element separate from the secure device processor and in communication therewith, the second verification based on secret information that is stored in the secure element memory without the secure element providing the secret information to the secure device processor;

generating, by the processing system, consumption information by monitoring the access to the content;

providing, by the processing system, the consumption information associated with the access to the content to the secure element, the consumption information indicating that the content has been presented by the device; and

preventing, by the processing system, the secure device processor from further accessing the content according to access instructions from the secure element, wherein the access instructions are responsive to the consumption information.

17. The method of claim 16, wherein the access instructions are based at least in part on digital rights management data included in the non-secret information.

18. The method of claim 16, wherein the secret information and the non-secret information are obtained by the secure element from a remote management server.

19. The method of claim 16, wherein the secret information includes a decryption key and an authentication credential.

20. The method of claim 16, wherein the secure element comprises a universal integrated circuit card (UICC), and wherein the secure device processor obtains the non-secret information via communication with a secure download management function of the UICC.
