Secure Vehicle Access via Elliptic Encryption and Remote Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current keyless entry systems for vehicles lack secure and efficient methods for multiple users to access and share vehicle access rights without physical meetings, relying on insecure digital data exchanges.
Innovation Solution
A method and system utilizing a remote data server and personal devices with an elliptic encryption curve to securely exchange and manage keys, allowing primary and secondary users to access a vehicle through encrypted data transmission and secure connections established via dedicated applications on mobile devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If digital data exchange is used for vehicle access, then convenience and automation are improved, but security is worsened due to potential interception by third parties
Solution Approach 1:
The patent introduces a remote server as an intermediary that mediates all key exchanges between users and the vehicle. The server generates and distributes encrypted keys, and verifies access requests, preventing direct unauthorized communication between potential attackers and the vehicle system. This intermediary architecture enables automated access while maintaining security through centralized control and encryption.
2Adaptability or versatility
If multiple users share vehicle access, then versatility is improved, but key management complexity is worsened requiring physical meetings for card exchange
Solution Approach 1:
The patent implements a self-service system where users can independently register, request access rights, and exchange keys through the mobile application without requiring physical meetings or manual intervention from administrators. The system automatically manages key generation, distribution, and revocation based on user requests and vehicle owner authorization, eliminating the complexity of manual key management while supporting multiple users.
3Reliability
If electronic cards are used for vehicle access, then security is improved compared to physical keys, but the number of electronic devices carried by users increases
Solution Approach 1:
The patent makes the mobile telephone serve multiple functions: it acts as both a communication device and a vehicle access key through the integrated application. The application uses the telephone's existing capabilities (wireless communication, processing power, display) to provide keyless entry, eliminating the need for separate electronic cards while maintaining security through encrypted key management and server verification.
