Abstract: [PROBLEMS] To safely and easily perform power cable communication with a server providing a desired service. [MEANS FOR SOLVING PROBLEMS] There is provided a communication relay device for relaying communication data between an information processing device and a communication network by utilizing a power cable where a communication signal is superimposed on a power signal. The communication relay device includes: an authentication information storage unit for storing authentication information for the communication relay device; a power plug which can be detachably attached to w power socket for connecting an electric device to the power cable; a connection detection unit for detecting that the power plug is connected to the power socket; an authentication unit for transmitting authentication information to the server via the power cable if the power plug is connected tot he power socket so that the server authenticates the communication relay device; and a communication relay unit for relaying the communication data from the information processing device for the communication network if the authentication by the authentication unit is sucessful.

Abstract: [PROBLEMS] To safely provide only unused band of a communication line contractor to a third person for free. [MEANS FOR SOLVING PROBLEMS] A communication device (20) radio-communicates with each of information processing devices and connects each of the information processing devices to a communication line provided by an ISP (Internet service provider). The communication device (20) includes: a contractor terminal judgment unit (200) for judging whether each of the information processing devices is managed by an ISP contractor who is allowed to install the communication device and connect it to the communication terminalaccording to the contract with the ISP; and a communication unit (210) for radio-communicating with each of the information processing devices by setting the contractor terminal as an information processing device managed by the contractor with a higher priority than a non-contractor terminal as an information processing device which is not a contractor terminal.
