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.
