Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Internet of Things devices communicate in plaintext, then communication simplicity is maintained, but data security deteriorates
Solution Approach 1:
The patent introduces a trusted device as an intermediary to generate and distribute communication keys between IoT devices. This mediator enables encrypted communication without requiring the IoT devices themselves to perform complex key generation, thus maintaining ease of operation while achieving data security through encryption.
Solution Approach 2:
The trusted device performs preliminary key generation and distribution before actual communication between IoT devices occurs. By pre-establishing the encryption keys through a trusted intermediary, the system prepares the security infrastructure in advance, allowing simple encrypted communication without burdening the IoT devices with complex cryptographic operations.
2Reliability
If encrypted communication is implemented between IoT devices, then data security is improved, but communication complexity increases
Solution Approach 1:
The trusted device serves as an intermediary that handles the complex key generation and distribution processes. IoT devices only need to acquire keys from the trusted device and use them for encryption/decryption, significantly reducing their operational complexity while maintaining strong security.
Solution Approach 2:
The trusted device automatically generates keys and distributes them to authorized IoT devices without requiring manual configuration. This self-service approach to key management simplifies the overall system operation while ensuring security, as the complex cryptographic operations are performed automatically by the trusted intermediary.
3Reliability
If a trusted device is introduced for key distribution, then communication security is enhanced, but system complexity increases
Solution Approach 1:
The trusted device performs multiple functions including key generation, key distribution, and authentication verification. By consolidating these security-related functions into a single multi-functional component, the system achieves enhanced security without proportionally increasing overall complexity, as one device handles multiple security tasks.
Solution Approach 2:
The trusted device acts as a centralized intermediary that simplifies the security architecture by providing a single point for key management. Rather than requiring each IoT device to independently manage complex cryptographic operations, the intermediary centralizes these functions, making the overall system more manageable despite the added component.
