Electronic appliance, network unit of electronic appliances, network of electronic appliances, and chip identification method

Abstract

Technology prevents the peripheral devices from being taken over, to suppress the remote-attack on the network of electronic devices by applying the physical chip identification devices to the network. To realize this, a plurality of electronic appliances composing the network is divided into peripheral devices and stem servers that manage the registration information of the peripheral devices. The stem servers may be under the central control, whereas the peripheral devices hold the physical chip identification devices. By managing the peripheral devices in the level of a device like this, the security of the entire network is effectively improved.
