Embodiment Construction

[0012] overview

[0013] The methods and systems described herein enable an end user of a communication device, such as a mobile phone, to select a security service provider to use a security component stored on the communication device. In one embodiment, the system includes a key escrow service that manages keys for one or more users and one or more security service providers. Typically, the security component and one or more keys for the security component are installed on each user communication device when the communication device is manufactured. These keys, or corresponding keys, are provided to a key escrow service. Each user device also includes a service provider selector ("SPS") module or software application that enables the user to select from available security service providers. The SPS transmits information identifying the selected service provider to the user's secure component over the secure channel in response to the user's selection. The key escrow serv...

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.
