Abstract

Systems and methods are described herein for enabling users to select from available secure service providers (each having a Trusted Service Manager (“TSM”)) for provisioning applications and services on a secure element installed on a device of the user. The device includes a service provider selector (“SPS”) module that provides a user interface for selecting the secure service provider. In one embodiment, the SPS communicates with a key escrow service that maintains cryptographic keys for the secure element and distributes the keys to the user selected secure service provider. The key escrow service also revokes the keys from deselected secure service providers. In another embodiment, the SPS communicates with a central TSM that provisions applications and service on behalf of the user selected secure service provider. The central TSM serves as a proxy between the secure service providers and the secure element.

maintaining, by a computer, at least one cryptographic key for a secure element of a network computing device, the at least one cryptographic key operable to provide secure access to the secure element via a secure communication channel;

receiving, by the computer, a selection of a trusted service manager (“

TSM”

) for facilitating a secure service;

obtaining, by the computer, from the selected TSM, information regarding the secure service and an application for the secure service; and

provisioning, by the computer, the secure service in the secure element using the obtained information, the obtained application, and the at least one cryptographic key.

2. The computer-implemented method of claim 1, further comprising creating a secure communication channel between the computer and the selected TSM to obtain the information regarding the secure service and the application for the secure service.

3. The computer-implemented method of claim 1, further comprising executing business logic for the secure element on behalf of the selected TSM.

4. The computer-implemented method of claim 1, wherein if the secure element included information related to a previous TSM that is different form the selected TSM. the method further comprising removing the information related to the previous TSM from the secure element.

5. The computer-implemented method of claim 1, wherein if the secure element included information related to a previous TSM that is different form the selected TSM, the method further comprising transmitting a message to the secure element commanding the secure element to remove the information related to the previous TSM from the secure element.

6. The computer-implemented method of claim 1, further comprising receiving confirmation of the selection of the selected TSM from another device other than the network computing device prior to provisioning the secure service at the secure element.

7. The computer-implemented method of claim 1, wherein the computer comprises a managed TSM.

22. The computer-implemented method of claim 1, wherein the selection of the TSM for facilitating the secure service is received from the network computing device.

23. The computer-implemented method of claim 1, further comprising:

receiving, by the computer, a selection of a second TSM for facilitating a second secure service;

obtaining, by the computer, from the second TSM, information regarding the second secure service and an application for the second secure service; and

provisioning, by the computer, the second secure service at the secure element using the obtained information regarding the second secure service, the obtained application for the second secure service, and the at least one cryptographic key.

24. The computer-implemented method of claim 23, further comprising removing information related to a TSM other than the second TSM from the secure element.

25. The computer-implemented method of claim 23, further comprising transmitting a message to the secure element commanding the secure element to remove information and an application related to a TSM other than the second TSM from the secure element.

26. The computer-implemented method of claim 23, further comprising communicating an instruction to the secure element to allow processing of only the second secure service.

27. The computer-implemented method of Claim 23, further comprising communicating an instruction to the secure element to block processing of secure services other than the second secure service.
