Enabling users to select between secure service providers using a key escrow service
First Claim
1. A computer-implemented method for providing a secure service to a network device comprising a secure element, the method comprising:
- maintaining, by a computer, at least one cryptographic key for the secure element, the at least one cryptographic key operable to provide secure access to the secure element via a secure communication channel;
receiving, by the computer, from the network device, a request to change trusted service managers (“
TSMs”
) from a first TSM to a second TSM;
causing, by the computer, the first TSM to lose access to the secure element by revoking the at least one cryptographic key from the first TSM in response to receiving the request to change TSMs; and
transmitting, by the computer, the at least one cryptographic key to the second TSM in response to receiving the request to change TSMs.

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.

11. A computer program product, comprising:
a non-transitory computer-readable medium having computer-readable program code embodied therein for providing a secure service to a communication device comprising a secure element, the computer-readable medium comprising; computer-readable program code for maintaining at least one cryptographic key for the secure element, the at least one cryptographic key operable to provide secure access to the secure element via a secure communication channel; computer-readable program code for receiving a request to change trusted service managers (“
TSMs”
) from a first TSM to a second TSM;computer-readable program code for causing the first TSM to lose access to the secure element by revoking the at least one cryptographic key from the first TSM in response to receiving the request to change TSMs; and computer-readable program code for transmitting the at least one cryptographic key to the second TSM in response to receiving the request to change TSMs. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A system for providing a secure service to a network device comprising a secure element, the system comprising:
-
a first network communication module that receives, from the network device, a request to change trusted service managers (“
TSMs”
) from a first TSM to a second TSM;a key escrow service that; maintains at least one cryptographic key for the secure element, the at least one cryptographic key operable to provide secure access to the secure element via a secure communication channel; and causes the first TSM to lose access to the secure element in response to receiving the request to change TSMs by revoking the at least one cryptographic key from the first TSM in response to receiving the request to change TSMs; and a second network communication module that transmits the at least one cryptographic key to the second TSM in response to receiving the request to change TSMs, wherein the key escrow service is communicably coupled to the first network communication module and to the second network communication module. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)
