Apparatus authentication device, apparatus authentication method, information processing device, information processing method, and computer program

A device and a method for enabling a high-security access control configuration to be built efficiently and correctly. Only the MAC address of a user-authorized controller (client) (351) is authenticated and registered in the MAC address table of a device (352). The device (352) executes MAC address filtering to allow the controller (351) (client), authenticated and registered in the MAC address table, to access the device. Registration completion notification and version adjustment are executed to build a reliable access control configuration. An apparatus authentication device (350) prevents an access from an unauthorized controller, which is not authenticated nor registered, and makes a server invisible to a controller attempting to obtain unauthorized apparatus authentication, thus implementing high-security access control.
