Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If encryption and decryption operations are performed using IoT devices with limited computing resources, then security is provided, but processing speed is slow and latency is high
Solution Approach 1:
The patent extracts the encryption and decryption operations from the IoT device and relocates them to an external server. The IoT device generates asymmetric key pairs and retains only the private key, while the server stores the public key and performs all encryption/decryption operations. This separation allows the computationally weak IoT device to maintain security functionality without being burdened by complex cryptographic calculations, thereby resolving the contradiction between security and processing speed.
2Reliability
If complex asymmetric encryption algorithms are implemented on IoT devices, then security is enhanced, but device complexity and resource requirements increase
Solution Approach 1:
The patent extracts the computationally intensive asymmetric encryption algorithm implementation from the IoT device and relocates it to an external server. The IoT device only needs to generate key pairs and store the private key, while the server handles the complex encryption/decryption operations using the stored public key. This reduces the computational burden and complexity requirements on the IoT device while maintaining strong security through asymmetric cryptography.
3Productivity
If traditional encryption methods requiring fast CPUs are used on IoT devices, then encryption speed improves, but device cost and complexity increase
Solution Approach 1:
The patent extracts the encryption speed requirement from the IoT device and relocates it to the server infrastructure. The IoT device generates asymmetric keys and sends data to be encrypted, while the server performs the encryption/decryption operations using its more powerful processing capabilities. This allows high-speed encryption without requiring expensive fast CPUs in the IoT devices, as the computational burden is shifted to the server.
