Abstract
A remote control relay device is connected between a network and a controlled device. The controlled device is remotely controlled from an external device over the network. The remote control relay device includes a communication controller, a storage memory, a control memory and a write controller. The communication controller exchanges control data with the external device over the network. The storage memory stores control data. The control memory stores control data used for external device authentication. The write controller controls sending and receiving of control data by the communication controller, reading of control data stored in the storage memory, and writing of control data to the control memory. The write controller reads and writes control data from the storage memory to the control memory only in response to operations that are not executed over the network.
