Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If direct electrical connection is required for physical key authentication, then authentication security is ensured, but authentication availability deteriorates when connection is not possible
Solution Approach 1:
The patent introduces a wireless communication intermediary (Bluetooth, WiFi, or other wireless protocols) as a mediator between the authentication client and the physical security key. This intermediary enables challenge-response authentication to occur remotely without requiring direct electrical connection, thus resolving the contradiction between maintaining security and improving availability.
2Ease of operation
If remote verification is implemented without direct electrical connection, then authentication availability is improved, but connection reliability deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where the authentication client and physical security key continuously verify each other's identity through cryptographic challenge-response protocols. This feedback loop ensures that even over unreliable wireless connections, the authentication process maintains security by confirming the legitimacy of both parties before completing the authentication.
3Adaptability or versatility
If wireless transmission is used for authentication data, then operational flexibility is improved, but data transmission security worsens
Solution Approach 1:
The patent replaces the mechanical electrical connection system with a wireless communication system that uses cryptographic mechanisms for security. Instead of relying on physical connection security, the system uses digital signatures, challenge-response protocols, and encrypted data transmission to protect authentication data, thus maintaining security while improving operational flexibility.

AI summary
A system for remotely verifying physical security keys and a method thereof are provided. The system includes a physical key, a control device, and a controlled platform. The control device is electrically connected to the physical key. The controlled platform is linked to the control device via digital transmission. The control device sends a verification application message to an application service program linked to the controlled platform through the digital transmission; according to the verification application message, the controlled platform responds to the control device via the digital transmission with a challenge value signing procedure to request a signature; according to the challenge value signature procedure, the control device performs a signature procedure on the physical key to complete verification. In this way, the physical key is remotely authenticated by the control device to achieve the purpose of improving information security.
