Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If security measures are applied at the time of introduction, then initial security protection is provided, but security becomes insufficient as time passes and new vulnerabilities emerge
Solution Approach 1:
The system performs preliminary actions by establishing baseline resource consumption profiles during normal operation before attacks occur. These baselines are recorded and stored for future comparison, enabling the system to detect anomalies when resource consumption deviates from expected patterns, thus preparing the system in advance for unknown threats
Solution Approach 2:
The system implements continuous feedback by constantly monitoring resource consumption and comparing it against established baselines. When deviations are detected, the system provides feedback that triggers security responses, creating a closed-loop system that adapts to new threats through ongoing observation and adjustment
2Measurement precision
If resource monitoring is performed continuously to detect DOS attacks, then detection capability is improved, but system complexity and computational load increase
Solution Approach 1:
The system creates simplified copies of normal resource consumption patterns as baseline profiles. Instead of analyzing complex real-time data streams, the system compares current consumption against these pre-established baseline copies, significantly reducing computational complexity while maintaining detection accuracy
Solution Approach 2:
The system transforms complex resource consumption data into simplified parameters by establishing baseline profiles during normal operation. This parameter transformation converts multifaceted resource usage patterns into comparable baseline metrics, making anomaly detection computationally efficient
3Measurement precision
If temperature-based corrections are applied to resource consumption data, then detection accuracy is improved, but processing time and computational overhead increase
Solution Approach 1:
The system performs preliminary temperature compensation by establishing baseline resource consumption profiles that already account for temperature effects during normal operation. This preliminary action eliminates the need for complex real-time temperature corrections, reducing processing time while maintaining accuracy

AI summary
A control device comprises: a measurement unit that measures the physical state of at least one electronic component to measure the temperature of a representative part thereof; a recording unit that records a model wave of the physical state of the electronic component, and the temperature of the representative part at the time of recording the model wave as a reference temperature; a correction unit that corrects the model wave based on the temperature of the representative part and the reference temperature; and a detection unit that adds up, at regular intervals, an absolute value of a difference between the measured physical state of the electronic component and the physical state of the corrected model wave, and determines whether or not the added value exceeds a threshold value for determining an unauthorized access that imposes excessive loads on resources to disturb operation of the control device or network.
