Enabling users to select between secure service providers using a key escrow service

摘要

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.

主权项

1. A computer-implemented method to provide secure services to computing devices comprising secure elements, comprising:
maintaining, by a key escrow service computing device, at least one cryptographic key for a secure element of a network computing device, the at least one cryptographic key operable to enable one of a plurality of trusted service managers (“TSMs”) to provide read and write access the secure element via a secure communication channel; receiving, by the key escrow service computing device, a selection of one of the plurality of TSMs, wherein if the secure element comprises information related to a previous TSM that is different from the selected TSM, the key escrow service computing device revokes the at least one cryptographic key from the previous TSM in response to receiving the request to select the TSM; and transmitting, by the key escrow service computing device, the at least one cryptographic key to the selected TSM in response to receiving the selection of the one of the plurality of TSMs to enable the selected TSM to access the secure element using the at least one cryptographic key.
