Engineering Contradiction Analysis
1Reliability
If traditional multi-level gateway systems are used to transfer sensitive information between networks of different sensitivity levels, then data security is improved, but device complexity and integration cost increase
Solution Approach 1:
The system segments data transfer into multiple unidirectional paths, with each path containing diode-type components that enforce one-way data flow. This segmentation prevents feedback loops and ensures data moves only from higher to lower sensitivity levels, maintaining security while simplifying the overall gateway architecture.
Solution Approach 2:
Diode-type equipment acts as an intermediary component between networks of different sensitivity levels. These components physically enforce unidirectional data flow, preventing direct bidirectional communication and eliminating the need for complex security protocols and monitoring systems.
2Reliability
If traditional multi-level gateway systems are used to prevent data leaks, then data security is improved, but cost increases
Solution Approach 1:
The system uses simple diode-type components that are inexpensive to manufacture and replace. These components provide reliable unidirectional data flow without requiring expensive security infrastructure, making the overall system more cost-effective while maintaining data security.
3Reliability
If fixed gateway configurations are used to ensure data security, then reliability is improved, but adaptability decreases
Solution Approach 1:
The gateway system allows dynamic reconfiguration of unidirectional data paths by activating or deactivating specific diode-type components. This enables the system to adapt to different security requirements and data flow patterns while maintaining the fundamental unidirectional security model, providing both reliability and flexibility.
