Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional centralized CSM systems are used, then system simplicity is maintained, but system robustness and security are compromised when central storage is attacked
Solution Approach 1:
The patent segments the centralized storage system into multiple distributed storage nodes across the blockchain network. Each node stores portions of cyber data independently, eliminating the single point of failure in traditional centralized systems. This segmentation approach directly resolves the contradiction by improving robustness through distribution while managing complexity through modular architecture.
Solution Approach 2:
The patent introduces blockchain technology as an intermediary layer between data storage and retrieval operations. The blockchain ledger acts as a mediator that coordinates distributed storage nodes, manages data integrity through consensus mechanisms, and provides secure access control. This intermediary approach improves system robustness while abstracting the underlying complexity from users.
2Reliability
If all cyber data is stored in the blockchain, then data integrity is ensured, but data retrieval efficiency deteriorates due to blockchain's inherent storage and query limitations
Solution Approach 1:
The patent segments data storage into two layers: critical integrity metadata is stored on the blockchain, while bulk cyber data is stored off-chain in distributed file systems. This segmentation ensures data integrity through blockchain's immutable ledger while maintaining retrieval efficiency by accessing bulk data from faster off-chain storage, directly resolving the contradiction between integrity and efficiency.
Solution Approach 2:
The patent transitions from a single-dimension storage approach (all data on blockchain) to a multi-dimensional storage architecture combining on-chain metadata storage with off-chain bulk data storage. This dimensional change allows the system to simultaneously achieve data integrity through blockchain's cryptographic verification and efficient retrieval through optimized off-chain access patterns.
3Productivity
If a fine-grained ledger structure is implemented, then data retrieval efficiency is improved, but system complexity increases
Solution Approach 1:
The patent implements a fine-grained ledger structure that segments the blockchain into specialized sub-ledgers for different data types (cyber intelligence, threat data, security events). Each sub-ledger is optimized for specific query patterns, improving retrieval efficiency. The segmentation organizes complexity into manageable, purpose-built components rather than a monolithic structure.
Solution Approach 2:
The patent creates a universal fine-grained ledger framework that handles multiple data types and query scenarios through a unified structure. This multi-functional ledger design improves efficiency across diverse use cases while providing a standardized interface that manages complexity through consistency and reusability.
4Reliability
If blockchain technology is integrated into CSM, then security and robustness are improved, but implementation complexity and computational overhead increase
Solution Approach 1:
The patent implements a universal blockchain-based CSM platform that provides multiple security functions (data integrity verification, secure multi-party collaboration, tamper-proof auditing, access control) through a single unified architecture. This multi-functionality approach improves security across various operations while managing implementation complexity through a standardized, reusable framework rather than separate solutions for each function.
Solution Approach 2:
The patent enables the blockchain-based CSM system to automatically perform security-critical operations such as data integrity verification, consensus validation, and threat detection without requiring manual security management. This self-service capability improves security through consistent automated enforcement while reducing implementation complexity by eliminating the need for manual security configuration and monitoring.
