Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional defense methods are used to detect malware, then the detection system is simple to implement, but the detection precision deteriorates due to the ability of ransomware to evade modern defense methods
Solution Approach 1:
The patent replaces traditional software-based malware detection methods with a physics-based power consumption analysis system. By measuring and analyzing the power consumption patterns of the CPU during encryption operations, the system can detect ransomware without relying on complex signature matching or behavioral analysis software, thus improving detection precision while maintaining relative system simplicity
Solution Approach 2:
The patent changes the detection parameter from software-level indicators (file extensions, registry keys, process names) to hardware-level physical measurements (power consumption). This parameter shift allows the system to detect encryption-based malware through their characteristic power signatures during cryptographic operations, bypassing the evasiveness of modern ransomware
2Measurement precision
If power consumption analysis is used to detect encryption operations, then the detection precision improves, but the use of energy increases due to continuous monitoring requirements
Solution Approach 1:
The system implements continuous power consumption monitoring to maintain constant readiness for detecting encryption operations. By continuously measuring power usage, the system can immediately detect and respond to ransomware activation without interruption or delay, ensuring uninterrupted protection while managing energy consumption through efficient monitoring intervals
Solution Approach 2:
The power monitoring system is integrated into the host device's existing power management infrastructure, allowing the device to monitor its own power consumption without requiring external monitoring equipment. This self-monitoring capability reduces additional energy overhead while maintaining detection precision
