Abstract
An apparatus and a method capable of efficiently and accurately constructing an access control configuration having high security are realized. Only the MAC address of a controller (client)authorized by a user is authenticated and registered in a MAC address table of a device, and the deviceperforms MAC address filtering for permitting access by the controller(client) which is authenticated and registered in the MAC address table. Furthermore, by making a registration completion notification and by performing version adjustment, a reliable access control configuration is constructed. The device authentication apparatusavoids access from an unauthorized party which is not authenticated and registered, and makes the presence of a server not known to the controller which attempts to illegally perform device authentication. Therefore, access control with high security is realized.
