Engineering Contradiction Analysis
1Reliability
If MAC address is used for device identification in Ethernet networks, then device connectivity and network management are enabled, but the system becomes vulnerable to spoofing attacks and faces MAC address depletion
Solution Approach 1:
The patent changes the identification parameter from MAC address (software-based, editable) to chip identification value (hardware-based, physically unique). This parameter change transforms the security model by using inherent physical characteristics of the semiconductor chip, making the identification value non-editable and resistant to spoofing attacks.
Solution Approach 2:
The patent extracts the chip identification value from the physical semiconductor chip and uses it as a network identifier. This copying approach allows the unique physical characteristic of the chip to be utilized for network identification without requiring physical presence or manual configuration, enabling automated secure device onboarding.
2Adaptability or versatility
If editable digital identification (MAC address) is used, then network configuration flexibility is achieved, but security against spoofing attacks deteriorates
Solution Approach 1:
The patent enables devices to automatically provide their chip identification value for network identification without requiring manual configuration or administration. This self-service approach maintains configuration flexibility while enhancing security, as each device autonomously presents its unique hardware-based identifier to the network.

AI summary
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.
