A replay attack from an unauthorized user is easily avoided by wireless communication authentication. A mobile node acquires an inherent identification number owned by a base station connected to the mobile node, and sends authentication packet data including the identification number and information providing transfer route information for packet data sent to the mobile node through a wireless link. A router holds an inherent identification number owned by a base station connected to the router, and, if the identification number held by the router agrees with the identification number included in the authentication packet data sent from the mobile node, registers the transfer route information in a route table based on the authentication packet data. |
