Vehicle Control via Smartphone NFC Authentication and HCE
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle security systems face challenges in integrating secure communication technologies like NFC, Bluetooth, and RFID due to issues with property rights and costs, particularly when applying Secure Element (SE) technologies such as UICC and baseband processors, which are owned by different entities, and the high costs associated with SD cards that are not widely supported in recent smartphones.
Innovation Solution
A vehicle control system using a smartphone or wearable device for authentication and control via NFC, Bluetooth, WiFi, or Beacon modules, employing Host Card Emulation (HCE) and Trusted Execution Environment (TEE) for secure key storage and communication, allowing door and engine control without the need for traditional vehicle keys, thereby bypassing SE-related property rights and cost issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Secure Element (SE) technologies such as UICC and baseband processors are used for vehicle authentication, then security is improved, but property rights conflicts and costs increase due to ownership by different entities
Solution Approach 1:
The patent uses Host Card Emulation (HCE) to create a virtual copy of the secure card functionality within the smartphone's host environment. Instead of requiring physical SE technologies owned by different entities, the system emulates card authentication functions through software-based HCE, eliminating property rights conflicts while maintaining security through the Trusted Execution Environment's protected key storage and authentication processes
2Ease of manufacture
If SD cards are used for authentication storage, then cost is reduced, but compatibility decreases as recent smartphones do not support SD cards
Solution Approach 1:
The patent replaces the mechanical SD card storage system with a software-based authentication system running in the Trusted Execution Environment of modern smartphones. The HCE technology enables the smartphone to emulate card functions using its existing secure elements and processing capabilities, eliminating the need for physical SD card slots while maintaining broad compatibility across recent smartphone models
3Adaptability or versatility
If multiple wireless communication modules (NFC, Bluetooth, WiFi, RFID, Beacon) are integrated for authentication, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal authentication framework where the Trusted Execution Environment provides a common secure foundation that supports multiple wireless communication modules (NFC, Bluetooth, WiFi, RFID, Beacon). The TEE's protected key storage and authentication mechanisms serve all communication types through a unified interface, allowing the system to support diverse communication protocols without proportionally increasing complexity, as the security infrastructure is shared across all modules
