Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional encryption technologies such as blockchain are used to protect digital assets, then general cyberattacks can be defended against, but high-level cyberattacks such as quantum computer cryptanalysis and EMP attacks can still breach the security
Solution Approach 1:
The patent divides digital assets into multiple fragmented data pieces and distributes them across different geographic locations and storage media. This segmentation ensures that even if one location is compromised by quantum attacks or EMP attacks, the complete asset remains secure as long as other fragments remain intact.
Solution Approach 2:
The patent introduces an intermediary recovery mechanism that uses traditional cryptography (non-quantum resistant) as a backup layer. When quantum-resistant cryptography fails or is compromised, the system can fall back to traditional cryptographic methods for asset recovery, providing a dual-layer security approach.
2Ease of operation
If digital assets are stored in centralized locations or single cloud services, then management is simplified, but the system becomes vulnerable to single points of failure from attacks or disasters
Solution Approach 1:
The patent segments asset storage across multiple geographic locations and storage media types (online, offline, cold storage). Each fragment is stored independently, eliminating single points of failure while maintaining manageable access through coordinated retrieval protocols.
Solution Approach 2:
The patent implements different storage characteristics for different asset fragments based on security requirements. Some fragments are stored online for quick access, others offline for security, and some in cold storage for long-term preservation. Each location has optimized properties suited to its specific security and access needs.
3Reliability
If all digital assets are converted to quantum-resistant cryptography, then future quantum attacks can be defended against, but current systems lack practical quantum-resistant solutions and the cost is prohibitive
Solution Approach 1:
The patent applies quantum-resistant cryptography partially to only the most critical asset fragments or access control mechanisms, rather than converting the entire system. This selective approach provides future-proof security where needed while avoiding the prohibitive costs of全面 conversion.
Solution Approach 2:
The patent prepares for quantum threats by implementing hybrid cryptographic systems now, combining current quantum-resistant algorithms with traditional cryptography. This preliminary action allows gradual transition to full quantum resistance as technology matures and costs decrease.
4Reliability
If multiple cloud services are used to store digital assets, then redundancy and security are improved, but managing separate systems becomes complex and difficult
Solution Approach 1:
The patent creates a universal management layer that can handle multiple cloud services and storage types through a single interface. This multi-functional system manages diverse storage locations (different clouds, offline storage, cold storage) uniformly, eliminating the need for separate management systems for each storage location.

AI summary
A system is provided robustly protects important information from high-level cyberattacks and physical destruction, including cryptographic analysis using quantum computers and electromagnetic pulse attacks, while enabling restoration without theft by a third party. The system encrypts and partitions file data using predetermined encryption and division algorithms based on a customer specified parameter, allots each file data to multiple sets of distributed file management groups comprising node groups at multiple bases in different regions of the world, distributes and records the file data to be saved in the nodes located at each base that belong to corresponding distributed file management groups, generates and encrypts index information of each distributed and recorded corresponding file data, and records the index information in node groups of a specified base in the consortium chain.
