Vehicle External Operation Security via NFC Authentication Token
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current smartphone-based systems for controlling vehicle operations from outside, such as parking maneuvers, are insecure due to unsecured communication interfaces and vulnerabilities to malware, leading to potential material and personal damage.
Innovation Solution
A method and apparatus that utilize a key device as an authentication token for secure external use, employing near-field communication (NFC) and Bluetooth Low Energy protocols for encrypted communication, along with a challenge-response authentication scheme and a dead man function to ensure secure remote control of vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If smartphone-based systems are used for controlling vehicle operations from outside, then ease of operation is improved, but security deteriorates due to unsecured communication interfaces and vulnerabilities to malware
Solution Approach 1:
A secure communication module is introduced as an intermediary between the smartphone application and the vehicle control system. This module establishes encrypted communication channels and validates authentication tokens, preventing direct unauthorized access while maintaining the convenience of smartphone-based control.
Solution Approach 2:
Authentication and encryption protocols are executed in advance before any control commands are transmitted. The system pre-establishes secure communication interfaces and validates user credentials, ensuring that security measures are in place before operational control is granted.
2Ease of operation
If unsecured communication interfaces are used for remote control, then ease of operation is improved, but object-affected harmful factors worsen due to potential material and personal damage
Solution Approach 1:
The secure communication module acts as a protective intermediary that filters and encrypts all communications between the smartphone and vehicle systems, preventing malware and unauthorized commands from reaching critical control functions.
Solution Approach 2:
The system implements pre-established security protocols including encrypted communication channels and authentication mechanisms that cushion against potential attacks before they can cause harm to the vehicle or its occupants.
3Reliability
If authentication mechanisms are added to secure remote control, then security is improved, but device complexity increases
Solution Approach 1:
The authentication system operates autonomously within the secure communication module, automatically validating tokens and managing encryption without requiring user intervention or complex configuration, thereby maintaining simplicity despite enhanced security.
Solution Approach 2:
The secure communication module integrates multiple security functions including authentication, encryption, and communication management into a single unified component, reducing overall system complexity while maintaining comprehensive security.
Data Source
AI summary
A method for external use of a device having a wireless communication interface by a program of a mobile device. External use is possible only when a key device serving as an authentication token communicates with the program. This increases the security of an entry method for a vehicle.
