Identity management on a wireless device
First Claim
1. A method for performing local authentication at a wireless device, the method comprising:
- receiving an association handle from a service provider, wherein the association handle indicates that the service provider has performed an association with a network entity;
receiving authentication information associated with a user of the wireless device;
locally verifying the authentication information at the wireless device;
generating a signature key based on the association handle and a session key associated with the service provider, wherein the session key is derived from a network authentication between the network entity and the wireless device, and wherein the session key is configured for use in performing a local authentication at the wireless device; and
signing an identity assertion, using the signature key, to indicate that the wireless device has locally verified the authentication information.

Abstract
A wireless device may perform a local authentication to reduce the traffic on a network. The local authentication may be performed using a local web server and/or a local OpenID provider (OP) associated with the wireless device. The local web server and/or local OP may be implemented on a security module, such as a smartcard or a trusted execution environment for example. The local OP and/or local web server may be used to implement a provisioning phase to derive a session key, associated with a service provider, from an authentication between the wireless device and the network. The session key may be reusable for subsequent local authentications to locally authenticate a user of the wireless device to the service provider.
