ELECTRONIC DEVICE NETWORK AND ELECTRONIC DEVICE

WIPO Patent Application WO/2021/241590

A1

[Problem] When physical nodes (electronic devices) constituting a physical network such as IoT are spoofed, any security measure for protecting a logical network is invalidated. Therefore, both centralized management of physical nodes to prevent spoofing and distributed management of logical networks such as blockchain are required at the same time, and it is necessary to devise a way for centralized management and distributed management, which are normally contradictory, to coexist on one closed physical network. [Solution] A closed physical network is achieved by placing, under centralized management, the physical address of an electronic device at the chip level, and distributed management is logically performed by making a dictionary recording the authentication of chips on the closed physical network (in a physical firewall) into a blockchain. In this way, the present invention is characterized in that the centralized management of physical nodes and the distributed management of logical nodes coexist, and the management and security of the entire closed physical network are efficiently improved.
