ROUTER FOR SUPPLYING ACCESS WITH MOBILE NODE AND ROUTING METHOD THEREFOR

摘要

PURPOSE: A router for supplying access with a mobile node and a routing method therefor are provided to exchange a packet between a mobile node and other node by performing a binding update process and a packet conversion process, thereby directly communicating the mobile node with the other node that does not have a necessary mobile function. CONSTITUTION: A data storage(140) stores data for generating at least an authentication key generation token. The first interface(110) receives a packet, or transmits the packet to a destination address recorded in a header of the packet to be transmitted. A packet monitor(120) outputs an authentication request packet if the outputted packet is the authentication request packet for requesting a mobile node to be authenticated. A controller(130) inputs the packet to generate the authentication key generation token in reference to the stored data, generates an authentication key to store the authentication key in the data storage(140), and outputs the authentication key generation token to the first interface(110). The first interface(110) inputs the generation token, and transmits the token to the mobile node.
