Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current industrial control systems lack effective integration of digital certificates, access control, and anomaly detection, making them passive in responding to network attacks and unable to dynamically regulate security.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional passive security measures are used in industrial control systems, then system simplicity is maintained, but the system cannot effectively respond to network attacks and lacks dynamic security regulation capability
Solution Approach 1:
The patent implements dynamic security regulation by enabling the industrial control system to automatically adjust security policies in real-time based on detected threats and anomalies. The system transitions from static, pre-configured security rules to dynamic policy adjustment, allowing security parameters to change adaptively according to the current security state and threat level.
Solution Approach 2:
The patent establishes a closed-loop feedback mechanism where the system continuously monitors network traffic, detects anomalies, analyzes threat patterns, and feeds this information back to automatically adjust security policies. This feedback loop enables the system to learn from past attacks and improve its security response over time without manual intervention.
2Reliability
If digital certificates and access control are integrated into industrial control systems, then identity authentication capability is improved, but the device complexity and operational overhead increase
Solution Approach 1:
The patent implements self-service automation where the system automatically performs certificate validation, access control decisions, and security policy enforcement without requiring manual administrative intervention. The automated security controller independently manages authentication and authorization processes, reducing the operational burden on system administrators.
Solution Approach 2:
The patent pre-configures security policies, digital certificates, and access control rules before system operation. These preliminary security configurations are established in advance and automatically activated when needed, eliminating the need for manual setup during operational phases and reducing operational overhead.
3Reliability
If active security response mechanisms are implemented, then the system's ability to detect and respond to anomalies is improved, but the processing time and computational resources increase
Solution Approach 1:
The patent implements rapid anomaly detection by skipping unnecessary processing steps and directly analyzing critical security parameters. The system uses efficient algorithms that quickly identify suspicious patterns in network traffic without performing exhaustive analysis, enabling fast detection and response to security threats while minimizing processing time.
