ABSTRACT:
To provide a system which, when data are incorporated into a household device via a bridging medium, is capable of ensuring security in the household device without installing security functions in the household device or bridging medium and regardless of whether the household device and a gateway in which security functions are integrated are connected via a network. The household device transfers data received via the bridging medium to the gateway, whereupon the security of the data is confirmed by security functions in the gateway. Only confirmed data are stored, whereupon a program or the like is executed. When the gateway and household device are not connected through a network, a signature is created in the gateway and this signature is verified in the household device.
