Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single system management device is used for all applications, then device complexity is low, but security reliability is insufficient for security applications
Solution Approach 1:
The system is divided into two independent system management devices: a first system management device for routine applications and a second system management device for security applications. This segmentation allows each device to be optimized for its specific purpose, with the second device providing enhanced security functionality while the first device handles general operations, thereby resolving the contradiction between security reliability and device complexity.
2Reliability
If frequent updates and modifications are made to improve security, then security reliability improves, but manufacturing cost increases
Solution Approach 1:
The second system management device is pre-configured with dedicated security functionality and resources during manufacturing. Security applications are pre-authorized to access specific resources of the second device, eliminating the need for frequent updates and modifications to enhance security. This preliminary configuration reduces manufacturing costs while maintaining high security reliability.
3Reliability
If security applications share resources with routine applications, then device complexity is low, but security reliability deteriorates due to potential bugs and vulnerabilities
Solution Approach 1:
Security-critical resources and functions are extracted from the first system management device and assigned to the second system management device. The second device maintains independent resource management for security applications, preventing bugs and vulnerabilities in the first device from affecting security operations. This extraction ensures security reliability while managing resource isolation complexity through dedicated security resource allocation.
4Reliability
If a secure mode operational environment is provided for security applications, then security reliability improves, but device complexity increases
Solution Approach 1:
The system dynamically selects which system management device to use based on the application type. Routine applications operate under the first system management device, while security applications automatically switch to the second system management device. This dynamic switching mechanism provides a secure operational environment for security applications without requiring the entire system to operate in a complex secure mode, thereby balancing security reliability with manageable system architecture complexity.
