Dynamic Key Validity Management for Secure Electronic Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of electronic devices for unlocking locking devices introduces security vulnerabilities, as existing methods lack robust authentication and key management, allowing for potential unauthorized access due to static key validity times and lack of remote control capabilities.
Innovation Solution
An electronic device with a communication module and processor that performs user authentication, changes the valid time of registered keys, and transmits an unlocking signal including the updated key information, enhancing security by preventing unauthorized access and enabling remote key management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a static key validity time is used for unlocking, then the unlocking process is simple and fast, but security vulnerability increases due to potential unauthorized access
Solution Approach 1:
The patent applies dynamics by transitioning from a static key validity time to a dynamic validity time that changes based on authentication results. The validity time is updated from an initial value to a final value after successful authentication, making the key management system adaptive and responsive to user actions, thereby enhancing security without requiring complex manual intervention
Solution Approach 2:
The patent implements feedback by establishing a closed-loop system where the authentication result directly influences the key validity time. After authentication, the system feeds back the authentication status to update the validity time, creating a responsive mechanism that adjusts key permissions based on user verification, thus improving security while maintaining operational simplicity
2Reliability
If remote key management capability is added, then security and control are enhanced, but device complexity increases
Solution Approach 1:
The patent applies universality by designing a unified authentication and key management system that handles multiple functions through a single integrated mechanism. The same authentication module manages both the authentication process and the validity time update, eliminating the need for separate complex subsystems and reducing overall system complexity while enhancing security
Solution Approach 2:
The patent implements self-service by enabling the system to automatically manage key validity times without requiring manual intervention. The authentication process automatically triggers validity time updates, and the system autonomously handles key permission adjustments, reducing operational complexity while maintaining strong security controls
