COMMUNICATION RELAY DEVICE, INFORMATION PROCESSING SYSTEM, CONTROL METHOD, AND PROGRAM

摘要

The present invention has an object to safely and easily perform power line communication with a server which provides a desired service. There is disclosed a communication relay device for relaying communication data between an information processing device and a communication network by use of a power line on which a communication signal and a power signal are superimposed, and the communication relay device includes an authentication information storage section for storing authentication information of the communication relay device; a power plug detachably attachable to a power socket for connecting an electric device to the power line; a connection detecting section for detecting that the power plug is connected to the power socket; an authentication processing section for transmitting the authentication information to a server via the power line in order to allow the server to authenticate the communication relay device, on condition that the power plug is connected to the power socket; and a communication relay section for relaying the communication data from the information processing device to the communication network, on condition that the authentication processing section succeeds in the authentication.
