Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If image capture devices are integrated into industrial control systems, then system functionality and monitoring capability are improved, but security vulnerabilities increase due to potential unauthorized access and malware introduction
Solution Approach 1:
An authentication module is introduced as an intermediary component between the image capture device and the industrial control system. This module verifies security credentials and establishes encrypted communication channels, preventing direct unauthorized access while maintaining system functionality. The intermediary validates each connection attempt through cryptographic authentication before allowing data transmission.
Solution Approach 2:
The system changes the security parameters of communication channels by implementing encrypted tunnels with authenticated sessions. Data transmission parameters are modified to include cryptographic handshakes, digital signatures, and session keys, transforming insecure communication into secure communication without altering the core imaging functionality.
2Reliability
If authentication sequences and encrypted tunnels are implemented, then system security is improved, but device complexity increases
Solution Approach 1:
The authentication system is designed to be self-service through automated cryptographic handshakes and credential verification. The authentication module automatically manages security credentials, establishes encrypted sessions, and handles key exchange without requiring manual configuration or intervention, reducing operational complexity despite the advanced security mechanisms.
Solution Approach 2:
The authentication module serves multiple functions: it verifies device identities, establishes encrypted communication channels, manages session security, and provides authentication logging. By consolidating these security functions into a single multi-functional module, the overall system complexity is managed more efficiently than implementing separate mechanisms for each security requirement.
