Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If signature-based scanning is used to detect malware, then known viruses can be identified, but sophisticated attacks and zero-day exploits cannot be detected
Solution Approach 1:
The security scanning function is divided into two independent modules: a signature-based scanner for detecting known malware and a forensic/behavioral analyzer for detecting sophisticated attacks. This segmentation allows each module to specialize in its strength without compromising the other, resolving the contradiction between reliability for known threats and adaptability for novel attacks.
Solution Approach 2:
The system performs preliminary forensic analysis and behavioral monitoring before malware can execute sophisticated attacks. By establishing baseline device behavior and pre-scanning applications during the charging phase, the system prepares detection mechanisms in advance, enabling it to identify both known signatures and anomalous behaviors of advanced threats.
2Reliability
If mobile devices perform security scanning, then malware can be detected, but user convenience is reduced due to additional操作步骤
Solution Approach 1:
The mobile device automatically performs security scanning and forensic analysis without requiring user intervention. The system self-initiates scans when connected to the secure charger, automatically compares application behavior against baselines, and isolates threats without user action, thereby maintaining high reliability while preserving ease of operation.
Solution Approach 2:
The security scanning function is merged with the existing charging operation. The secure charger simultaneously performs power delivery and security scanning, combining two functions into a single user action (plugging in the charger). This eliminates the need for separate scanning steps, maintaining user convenience while ensuring device security.
3Reliability
If security scanning is performed during device operation, then real-time protection is provided, but device performance and battery life are reduced
Solution Approach 1:
Instead of continuous scanning during device operation, the system performs periodic security scans during charging phases when the device is already connected to power. This periodic action aligned with natural user behavior patterns (charging overnight or between uses) provides real-time protection capability without the constant performance overhead of continuous scanning.
Solution Approach 2:
The security scanning operation is merged with the charging operation, utilizing the device's idle charging time for forensic analysis. This combination allows intensive security processing to occur when the device is already powered and connected, eliminating the need for separate scanning operations that would consume additional battery life and impact performance during active use.
4Reliability
If bidirectional trust verification is implemented, then application authenticity is ensured, but system complexity increases
Solution Approach 1:
The secure charger acts as an intermediary that facilitates bidirectional trust verification between applications and devices. Rather than requiring direct complex verification protocols between applications and the device, the charger mediates the process by scanning applications, verifying signatures, and providing a trust certificate, thereby simplifying the overall system architecture while ensuring application authenticity.
