Automated Authentication for Agricultural Devices via Data Bus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for authenticating agricultural implements coupled via a data bus require operator input and internet or mobile access, leading to potential errors and unsafe operating conditions due to unverified devices.
Innovation Solution
An automated authentication method where each agricultural device is independently verified through an authentication device via a data bus, using identification numbers and random numbers to generate and compare device keys, ensuring secure and operator-independent authentication without internet or cellular access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If operator input is required for authentication via Internet or mobile radio, then authentication can be performed with external access, but authentication becomes error-prone and requires operator involvement
Solution Approach 1:
The authentication system performs self-service authentication automatically between agricultural devices without requiring operator input. The control devices autonomously exchange authentication data and verify each other, eliminating human error and operator dependency while maintaining authentication capability.
Solution Approach 2:
The patent introduces an intermediary authentication mechanism where control devices use stored authentication data and generated random numbers as mediators to verify each other automatically. This intermediary process enables reliable authentication without direct operator involvement or external internet/mobile radio access.
2Adaptability or versatility
If operator input is required for authentication, then authentication can be performed, but the process becomes time-consuming and complex
Solution Approach 1:
The control devices automatically perform authentication operations without operator intervention. The system self-manages the entire authentication process including data exchange, random number generation, and verification, making operation simple while maintaining authentication capability.
3Productivity
If authentication is not performed, then device coupling is simpler and faster, but unsafe operating conditions may occur due to unverified devices
Solution Approach 1:
The system performs automatic self-service authentication that occurs rapidly without operator intervention. This automated process maintains fast device coupling speed while ensuring safety through verification, eliminating the trade-off between speed and safety.
Solution Approach 2:
The authentication process performs preliminary verification to prevent unsafe operating conditions before devices begin joint operation. By proactively verifying device authenticity, the system prevents harmful effects while maintaining efficient operation.

AI summary
The method involves coupling agricultural devices (10,11) to authentication device (12) through data bus (13) automatically and independently. The agricultural devices of authentication (14,15) are subjected to direct data exchange (18) or indirect data exchange (16,17) between successful authentication. The agricultural devices are operated, when data exchange is successfully authenticated. The agricultural devices are not operated, when data exchange is not successfully authenticated. An independent claim is included for an authentication device for authentication of agricultural devices.
