Embodiment approach

[0098] According to one embodiment, if application-layer security is to be re-established after a handover (e.g., an access-layer handover), binding the security credentials used for such subsequent application-layer authentication to the Forward bootstrapping of security credentials such as those used in handover access layer authentication, certificates used in previous application layer authentication, or even pre-handover access layer authentication.

[0099] In the embodiments described herein, independent identity providers may be used. For example, MNO A 323 may not be an OpenID identity provider and / or identity management functions may be performed by another third party. A third-party identity provider may use a pre-established relationship with the MNO A 323 to act in the role of an OpenID Provider, and use a protocol such as OpenID / EAP-SIM or OpenID / GBA bootstrapping capabilities to provide access stratum credentials 330 from the MNO A 323 Authenticate and Bootstra...

Abstract

Persistent communication layer credentials generated on a persistent communication layer at one network may be leveraged to perform authentication on another. For example, the persistent communication layer credentials may include application-layer credentials derived on an application layer. The application-layer credentials may be used to establish authentication credentials for authenticating a mobile device for access to services at a network server. The authentication credentials may be derived from the application-layer credentials of another network to enable a seamless handoff from one network to another. The authentication credentials may be derived from the application-layer credentials using reverse bootstrapping or other key derivation functions. The mobile device and / or network entity to which the mobile device is being authenticated may enable communication of authentication information between the communication layers to enable authentication of a device using multiple communication layers.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Patent Application No. 61 / 428,663, filed December 30, 2010, which is hereby incorporated by reference in its entirety. Background technique [0003] Users can generally continue to use services while roaming between networks. Handover may be performed, for example at the access layer, when a user moves from a location served by a current network to a location served by a target network. When performing a handover, the user may need to be authenticated to the target network that is serving the location into which the user is moving. Authentication at the access layer can occur at each handover, and the user device can use pre-provisioned credentials to access the target network at the access layer. [0004] A user's communication device may communicate using a layered communication mechanism. In many cases, the different communication layers each require their own s...
