Abstract
A closed physical network can be realized by putting physical addresses of electronic apparatuses under the central management in the chip level. Simultaneously, the decentralized management can be realized logically by converting the dictionary recording identifications of chips on the closed physical network (inside the physical firewall) to a blockchain. By this way, the present invention is characterized by making the central management of physical nodes and the decentralized management of logical nodes coexist and improving management and security of the entire of the closed network effectively.
