Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing communication technologies are used for data retrieval from databases, then communication speed and ease of operation are maintained, but security and reliability deteriorate due to vulnerability to interception and manipulation by unauthorized entities
Solution Approach 1:
The patent introduces intermediary devices (first intermediary device, second intermediary device) that act as mediators between the database and network devices. These intermediaries verify information using cryptographic hashes and digital signatures before allowing access, thereby securing communication without requiring direct complex security mechanisms at every endpoint.
Solution Approach 2:
The system performs preliminary verification actions by storing cryptographic hashes of information in the database before actual data retrieval. When a network device requests data, the intermediary device can quickly verify the integrity of retrieved information by comparing it against pre-stored hashes and validating digital signatures, eliminating the need for complex real-time security checks.
2Reliability
If cryptographic verification mechanisms are implemented to secure data communication, then security and reliability improve, but processing time and device complexity increase
Solution Approach 1:
Cryptographic hashes of information are pre-calculated and stored in the database during data insertion. This preliminary action allows intermediary devices to perform rapid verification by simply comparing retrieved data against pre-stored hashes, rather than performing complex cryptographic computations during each access operation.
Solution Approach 2:
The system creates and stores cryptographic copies (hashes and digital signatures) of the original information. These copies serve as verification tokens that can be quickly compared against the retrieved data without requiring the original complex security infrastructure, thereby reducing verification time while maintaining data integrity.
3Reliability
If secure memory arrays with registers are used to define and validate data segments, then security against unauthorized access improves, but manufacturing complexity and device complexity increase
Solution Approach 1:
The patent employs standard memory arrays and register structures that serve multiple functions: storing data, storing cryptographic hashes, storing digital signatures, and performing verification operations. This multi-functionality reduces the need for specialized security hardware components, thereby simplifying manufacturing while maintaining strong access control capabilities.
