Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If centralized authentication systems are used for electric vehicles and drones, then implementation is simpler, but security and scalability deteriorate due to single points of failure and vulnerability to cyber-attacks
Solution Approach 1:
The authentication system is segmented into multiple distributed nodes forming a consortium blockchain network, eliminating the centralized authentication server. Each node independently validates authentication requests, distributing security responsibilities and removing single points of failure while maintaining system reliability.
Solution Approach 2:
Smart contracts serve as intermediaries between devices and the authentication system. These self-executing contracts on the blockchain automatically verify credentials and manage authentication logic, providing secure, transparent, and tamper-proof mediation without centralized control.
2Ease of manufacture
If centralized authentication systems are used, then initial setup is easier, but scalability worsens due to bottlenecks in handling computational and communication demands
Solution Approach 1:
The system divides authentication processing across multiple consortium blockchain nodes, allowing parallel validation of authentication requests. This distributed architecture eliminates computational bottlenecks and enables the system to scale horizontally by adding more nodes to handle increasing device volumes.
Solution Approach 2:
The consortium blockchain network dynamically adapts to scaling demands by allowing new nodes to join the network. As the number of electric vehicles and drones increases, additional authentication nodes can be incorporated, and the system automatically adjusts its consensus and validation processes to maintain performance.
3Adaptability or versatility
If wireless communication channels are used for data exchange, then connectivity and mobility are improved, but security deteriorates due to vulnerability to spoofing, eavesdropping, and unauthorized access
Solution Approach 1:
The system replaces traditional centralized authentication mechanisms with cryptographic verification based on blockchain technology. Public-private key pairs provide mathematical security guarantees, and digital signatures authenticate communications over wireless channels without relying on vulnerable centralized infrastructure.
Solution Approach 2:
Smart contracts act as secure intermediaries that verify device credentials and authentication requests through cryptographic proofs. This intermediary layer on the blockchain ensures that wireless communications are authenticated and authorized without exposing sensitive security logic to potential attacks.
4Ease of operation
If sensitive data is stored and transmitted in centralized systems, then data access is simplified, but privacy deteriorates due to risks of data misuse
Solution Approach 1:
The system extracts sensitive personal information from the authentication process. Instead of storing and processing identifiable user data, the blockchain stores only cryptographic credentials and device identifiers. Authentication verification occurs without exposing sensitive personal information, protecting user privacy while maintaining operational simplicity.
Solution Approach 2:
Smart contracts serve as privacy-protecting intermediaries that verify authentication credentials without accessing or storing sensitive personal data. The verification process relies on cryptographic proofs and blockchain-stored credentials, enabling data access simplicity while inherently protecting user privacy through technical design.
