Abstract:
1. An apparatus for managing access to a network resource, comprising: (a) a network interface that employs a packet-based protocol to send and receive packets; and (b) a router for enabling a mobile node to access the network resource, wherein the router performs actions, including: forwarding a request for access to the network resource; receiving a single instance of a token from an agent in response to the request; and handing over the mobile node to another router without requiring validation of the single instance of the token for the handover, and providing the single instance of the token to the other router, wherein the other router validates the single instance of the token based on the agent's public non-symmetric key and employs the validated single instance of the token to determine what network resource the mobile node is authorized to access.
