Abstract: The invention proposes a system for authenticating and authorizing network services comprising: a mobile device being adapted to, upon receipt of an information message indicating at least one network access type, determine the network access type, to create a start message containing at least a user identity, and to encapsulate the start message in an authentication message compatible with the access network identified in the information message, and an access controller for reading the encapsulated message from the mobile and forwarding the encapsulated message to an authentication server identified in the encapsulated message. The invention also proposes a corresponding method for authenticating and authorizing network services, and an access control device, a subscriber device and a router device.

Abstract: A method and system for supporting mobile routers in Internet Protocol version 6 (IPv6) is provided. A mobile router obtains a care-of-address associated with an address configuration. The mobile router registers the care-of-address with a home agent. A bi-directional tunnel is established between the mobile router and the home agent. Packets are then forwarded via the bi-directional tunnel.

Abstract: A system and method for three-party authentication and authorization. The system includes an authorizer that authorizes requestors, a client that makes a request, and a local attendant that provides a conduit through which messages between the client and the authorizer pass. The authorizer, the client, and a peer on which the requested resource may be accessed are each in separate domains. A domain is defined as a set of one or more entities such that if the set includes more than one entity, a connection between any two of the entities in the set can be secured by static credentials that are known by each of the two entities. A subscriber identity module (SIM) may be used to generate a copy of a key for the client to be used in accessing a requested resource.

Abstract: A system is provided for prefix delegation with a pre-configured home agent, having a home address, and having a set of mobile router prefixes that are available to delegate to mobile routers. The transceiver of the home agent receives a prefix request option from a mobile router to request a prefix. The home agent assigns a prefix by combining a selected one of the set of mobile router prefixes with at least a part of the home address of the home agent, and sends the assigned prefix to the mobile router. Alternatively, the home agent assigns a prefix by combining a selected one of the set of mobile router prefixes with at least a part of the home address of the mobile router, and sends the assigned prefix to the mobile router.
