Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing physical security key authentication methods require direct electrical connection to an electronic device, leading to security risks when such connection is not possible, thereby compromising information security.
Innovation Solution
A system and method for remotely verifying physical security keys using digital transmission to enable authentication procedures without direct electrical connection, involving a control device, controlled platform, and registration and authentication database to confirm the legitimacy of the physical key.
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 an intermediary device that acts as a bridge between the physical key and the controlled platform. This intermediary receives authentication requests, forwards them to the physical key via digital transmission, and relays the verification results back. This mediator enables authentication without direct electrical connection between the physical key and the controlled platform, resolving the contradiction between security and availability.
Solution Approach 2:
The patent replaces the traditional mechanical electrical connection system with a digital transmission system. Instead of requiring physical electrical contact between the key and device, the system uses digital signals transmitted through communication protocols. This substitution maintains authentication security while enabling remote authentication scenarios, thus improving authentication availability without compromising security.
2Ease of operation
If remote verification is implemented without direct electrical connection, then authentication availability is improved, but verification complexity increases
Solution Approach 1:
The patent segments the authentication system into distinct functional modules: the controlled platform, the intermediary device, and the physical key. Each component has a specific responsibility - the platform initiates authentication, the intermediary manages communication and signal transmission, and the key performs verification. This segmentation reduces overall system complexity by distributing functions across separate components rather than requiring a complex integrated system.

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.
