Innovation Solution
The implementation of an identification device that generates a physically random, uneditable private key for each semiconductor chip, which serves as a unique physical address, and integrates with blockchain technology to secure network authentication, ensuring the unique linkage of logical and physical nodes without manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If logical addresses are used for network authentication, then network management becomes simplified, but security against manipulation and hijacking deteriorates
Solution Approach 1:
The patent introduces a stem node as an intermediary authority that issues certification codes to peripheral nodes. This mediator verifies the authenticity of physical addresses and prevents hijacking by providing a trusted third party that binds logical addresses to verified physical identities, thus maintaining security while enabling simplified network management through centralized authentication.
Solution Approach 2:
The patent creates a certification code that copies and verifies the physical address information through a trusted stem node. This certification process produces a verified replica of the physical identity that can be used for authentication without exposing the actual physical address to manipulation, thereby preventing hijacking while maintaining operational simplicity.
2Adaptability or versatility
If physical addresses are made manipulatable for flexibility, then adaptability improves, but security and authenticity deteriorate
Solution Approach 1:
The patent performs preliminary verification of physical addresses by stem nodes before they are activated in the network. This advance authentication ensures that only verified physical addresses are assigned logical addresses, preventing future manipulation while maintaining flexibility for legitimate address changes through the authenticated system.
Solution Approach 2:
The stem node acts as an intermediary that mediates between the need for physical address flexibility and security requirements. It verifies and certifies physical addresses, allowing legitimate changes while preventing unauthorized manipulation, thus enabling adaptability without compromising authenticity.
3Reliability
If decentralized P2P network is implemented, then system robustness improves, but authentication management complexity increases
Solution Approach 1:
The patent segments the network into stem nodes and peripheral nodes with clearly defined roles. Stem nodes handle authentication and certification functions, while peripheral nodes focus on data processing and storage. This segmentation distributes authentication management to specialized nodes, maintaining robustness through decentralization while reducing overall system complexity through functional separation.
Solution Approach 2:
The stem nodes serve multiple functions including authentication, certification issuance, and network coordination, while peripheral nodes handle data storage and processing. This multi-functionality allows the decentralized P2P structure to maintain robustness without requiring every node to handle complex authentication, as specialized stem nodes manage these functions universally across the network.
4Reliability
If more authentication layers are added to prevent hijacking, then security improves, but network operation speed deteriorates
Solution Approach 1:
The patent performs authentication and verification of physical addresses in advance through stem nodes before nodes join the network. This preliminary security check ensures that once authenticated, nodes can operate with verified identities without requiring continuous complex verification, thus maintaining high security while preserving network operation speed during normal transactions.

AI summary
An authenticated network in which a physical network including physical nodes with actual physical substances and a logical network including logical nodes without actual substances are uniquely linked to expand public ledger technology, which secures Peer-to-peer (P2P) type communication on a logical network, to a physical network, is provided. The authenticated network includes a private key uniquely linked to a public key. The private key is generated by a key generator and an identification device having physical substance and included in an identification core. The private key is regarded as a physical address of the identification core and is confined in the identification core. The public key is publicized as a logical address of a logical node. The logical node and the physical node are uniquely linked by the public key and the private key. The security of the whole network is thus effectively improved.
