Vehicle Authentication via Multi-Channel Cross-Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The spread of autonomous vehicles is hindered by security concerns related to hacking, particularly in connection-based recognition techniques, where malicious operations can occur due to the potential for fake vehicle information being transmitted, leading to incorrect detection of neighboring vehicles' positions.
Innovation Solution
A method and system for authenticating external vehicles using multiple communication channels with different transmission speeds, where a first vehicle receives position and identity information through one channel and verifies the authenticity of a second vehicle based on distance information calculated from both channels, thereby detecting and preventing malicious operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If connection-based recognition technique is used to enable autonomous driving, then the vehicle can recognize external environment and neighboring vehicles, but the system becomes vulnerable to hacking and fake vehicle information transmission
Solution Approach 1:
The patent introduces an intermediary verification mechanism using multiple communication channels (first and second channels) to authenticate neighboring vehicles. The verification server acts as a mediator that receives authentication requests and validates vehicle identities through cross-channel verification, preventing fake vehicle information from being accepted without proper authentication
Solution Approach 2:
The patent changes the authentication parameter from single-channel trust to multi-channel verification. By requiring consistent vehicle identity information across multiple communication channels with different characteristics, the system transforms the security parameter from vulnerable single-point authentication to robust multi-factor verification
2Ease of operation
If single communication channel is used for vehicle authentication, then the system is simple to operate, but it cannot detect fake vehicle information or hacking attempts
Solution Approach 1:
The patent segments the authentication process into distinct communication channels (first channel and second channel), each transmitting authentication information independently. This segmentation allows the system to verify vehicle identity through multiple separate paths, making it possible to detect inconsistencies that indicate fake information or hacking attempts
3Reliability
If multiple communication channels are used for vehicle authentication, then the system can detect and prevent hacking, but the device complexity increases
Solution Approach 1:
The patent implements a universal authentication framework where the same verification server and authentication protocol can handle multiple communication channels. The verification server performs the same authentication function across different channels, reducing the need for channel-specific complex logic and allowing the system to scale without proportionally increasing complexity
