Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is transmitted directly between IoT devices and edge computing devices without a secure tunnel proxy, then network communication efficiency is maintained, but data security and integrity are compromised due to unauthorized access risks
Solution Approach 1:
A secure tunnel proxy is introduced as an intermediary component between IoT devices and edge computing devices. The proxy establishes encrypted tunnel connections, manages authentication, and filters traffic, thereby providing security without requiring complex changes to the underlying IoT device architecture. The proxy acts as a dedicated security layer that handles cryptographic operations and access control policies.
Solution Approach 2:
The network architecture is segmented into distinct functional layers: IoT device layer, secure tunnel proxy layer, and edge computing device layer. This segmentation isolates security-critical functions in the proxy layer, allowing IoT devices to maintain simple communication protocols while the proxy handles encryption, authentication, and security policy enforcement separately.
2Reliability
If traditional data transmission methods are used between IoT sensors and edge computing devices, then implementation simplicity is maintained, but data integrity and confidentiality are compromised in large network environments
Solution Approach 1:
Security measures are implemented preliminarily through the tunnel proxy before data reaches the edge computing devices. The proxy pre-establishes encrypted channels, performs authentication, and validates data integrity using cryptographic signatures. This preliminary security processing prevents the need for complex security implementations at each IoT device and edge device endpoint.
Solution Approach 2:
The secure tunnel proxy serves as a dedicated intermediary that implements security protocols, thereby simplifying the overall system implementation. Instead of requiring each IoT device and edge device to implement full security stacks, the centralized proxy handles encryption, decryption, authentication, and integrity verification, reducing implementation complexity at the endpoints.
3Reliability
If secure encryption protocols are implemented for all data transmissions, then data confidentiality is improved, but computing resource consumption increases
Solution Approach 1:
The secure tunnel proxy acts as a dedicated intermediary that performs all computationally intensive cryptographic operations. The proxy handles key management, encryption, decryption, and authentication, thereby offloading these resource-intensive tasks from battery-constrained IoT devices and edge computing devices. This concentration of cryptographic processing in the proxy minimizes energy consumption across the distributed system.
Solution Approach 2:
The tunnel proxy implements self-service security mechanisms including automatic key generation, certificate management, and session establishment. By automating these security functions at the proxy level, the system reduces the computational burden on IoT devices and edge devices, allowing them to focus on their primary functions with minimal security-related resource consumption.
