<p>In this control device, a communication unit (24) performs wireless communication between portable communication terminals (4, 6) having a function as an electronic key. An authentication unit (22, S100-S130) compares the key information of electronic keys via a communication unit, and when the key information comparison has been established, the terminal with which the communication unit has performed wireless communication is determined to be an electronic key capable of an apparatus operation, and operation of an apparatus is permitted. A storage unit (22a) stores the key information of a primary electronic key for apparatus operation as key information used by the authentication unit in the authentication of an electronic key, and stores the key information of a secondary electronic key such that the operation of an apparatus is temporarily permitted. A disabling unit (22, S140-S190, S210-S250) disables key information necessary for the authentication unit to authenticate the secondary electronic key after waiting for disabling conditions for the secondary electronic key to be satisfied when the secondary electronic key is authenticated by the authentication unit on the basis of the key information stored in the storage unit and the operation of the apparatus is permitted by means of the secondary authentication key.</p> |
