Wireless Terminal Command Processing for Vehicle Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of a radio communication module in On-Board Diagnostics (OBD) systems poses a security risk as it allows malicious third parties to remotely control vehicles through mobile terminals, potentially threatening passenger safety by transmitting wrong or forged command data.
Innovation Solution
A command data processing method that selectively delivers command data to vehicles based on the operation status of the vehicle and the type of data, using different communication protocols, and verifying the identity of the mobile terminal to prevent unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the OBD is equipped with a radio communication module to enable remote control, then the ease of operation is improved, but the security risk increases allowing third parties to control the vehicle illegally
Solution Approach 1:
The patent introduces an intermediary authentication mechanism between the mobile terminal and the vehicle control system. The authentication server acts as a mediator that verifies the legitimacy of control requests before allowing communication between the mobile terminal and the vehicle, thus enabling remote control while preventing unauthorized access
Solution Approach 2:
The patent implements preliminary authentication and authorization checks before allowing remote control commands to be executed. By verifying the mobile terminal's identity and control permissions in advance, the system prevents malicious third parties from controlling the vehicle while maintaining legitimate remote access functionality
2Speed
If command data is transmitted without verification to enable responsive control, then the speed of response is improved, but the reliability decreases due to potential malicious control
Solution Approach 1:
The patent performs authentication and verification actions before the actual control command execution. The mobile terminal and vehicle establish authenticated communication channels in advance, and control permissions are pre-verified, allowing rapid execution of legitimate commands while blocking malicious ones before they can cause harm
3Adaptability or versatility
If all command data from mobile terminals is accepted, then the adaptability is improved, but the safety deteriorates due to potential malicious applications
Solution Approach 1:
The patent implements differential access control where different mobile terminals are granted different levels of control permissions based on their authentication status. Legitimate user terminals receive full control access while unauthenticated or malicious terminals are completely blocked, allowing high adaptability for authorized users while maintaining safety through selective restriction

AI summary
A command processing method of a wireless terminal capable of communicating with a transportation means and a mobile terminal e is provided to process command data transmitted from the mobile terminal to the transportation means. A command data processing method of a radio communication terminal capable of communicating with a transportation means and a mobile terminal according to the present disclosure includes receiving command data destined for the transportation means from the mobile terminal; checking an operation status of the transportation means; determining whether to deliver the command data to the transportation means based on the operation status of the transportation means and information on the command data; and delivering, when the command data is determined to be delivered to the transportation means, the command data to the transportation means.
