AUTHENTICATION AND SECURE CHANNEL SETUP FOR COMMUNICATION HANDOFF SCENARIO

摘要

PROBLEM TO BE SOLVED: To use authentication information of a persistent communication layer which is generated on a persistent communication layer in one network to perform authentication in another network.SOLUTION: For example, authentication information of a persistent communication layer may include authentication information of an application layer derived on the application layer. The authentication information of the application layer may be used to establish authentication information for authenticating a mobile device for access to services at a network server. The authentication information may be derived from the authentication information of an application layer in another network to enable a seamless handoff from one network to another network. The authentication information may be derived from the authentication information of the application layer using reverse bootstrapping or other key derivation functions. The mobile device and/or network entity to which the mobile device is authenticated may enable communication of authentication information between the communication layers to enable authentication of a device using a plurality of communication layers.
