Innovation Solution
A method for hierarchical Internet trust sharing is introduced, which includes configuring real address management and identity authentication modules at central nodes, managing data through central and local data management modules, and utilizing a blockchain for secure data storage and consensus, enabling efficient trust evaluation and data sharing across domains.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple core and complex edges Internet architecture is used, then the system structure is simplified, but node behavior becomes unreliable leading to security problems
Solution Approach 1:
The patent segments the Internet architecture into hierarchical domains with central nodes and communication nodes. Each domain is managed independently with its own trust evaluation mechanism, allowing simplified local structures while maintaining reliable trust management through domain segmentation and centralized coordination.
2Adaptability or versatility
If traditional trust management systems are used for Internet nodes, then identity authentication and data sharing are provided, but the systems face challenges in providing flexible identity authentication, efficient data consensus, and low storage solutions for large-scale networks
Solution Approach 1:
The patent introduces a hierarchical domain dimension to trust management, organizing nodes into multiple levels (central nodes and communication nodes within domains). This dimensional organization enables flexible identity authentication at different levels while distributing storage and consensus requirements, reducing overall system complexity for large-scale networks.
3Productivity
If traditional trust management systems are used, then trust data sharing is provided, but availability, effectiveness, and reliability in trust data sharing are compromised
Solution Approach 1:
The patent introduces central nodes as intermediaries within each domain that coordinate trust evaluation and data sharing among communication nodes. These intermediaries maintain local trust relationships and coordinate with other domains, improving data sharing efficiency while ensuring reliability through hierarchical verification and blockchain-based consensus for cross-domain operations.

AI summary
A method for hierarchical Internet trust sharing includes dividing a network into intra-domain and inter-domain layers based on a management domain; performing authentication on a central certificate through a CA and publishing the central certificate to a blockchain; managing by the central node, a certificate of each communication node based on a real address; collecting by the central node, temporary data reported by each communication node every preset time interval, generating a trust evaluation value of each communication node based on the temporary data and forming a format file from the trust evaluation values; generating by the central node, a file digest from the format file at each preset time interval, and publishing the file digest verified by central nodes in the inter-domain to the blockchain; and automatically deleting by the blockchain, data from the time interval 1 to the time interval (N-T-1) to retain blockchain header information.
