Abstract
A new controller (supporting device authentication) is a controller which performs encrypted communication with a device which has succeeded in mutual authentication using an electronic certificate, and the controller includes: a determining unit that determines whether or not a communication target device with which communication is to be performed is an authentication support device that supports the mutual authentication; a functional restriction unit that, when the communication target device is determined not to be the authentication support device by the determining unit, imposes a functional restriction on one or more functions of the communication target device which are operable by the new controller (supporting device authentication); and a communication unit which performs communication in plain text with the communication target device with the functional restriction imposed by the functional restriction unit.
