Vehicle Platoon Message Authentication via Signal Pilot Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In coordinated vehicle platooning, there is a need to verify the authenticity of wireless messages received among vehicles to prevent malicious actors from interfering with the communication, as existing systems lack effective methods to distinguish between authentic and inauthentic messages.
Innovation Solution
The proposed solution involves using signal pilots to authenticate wireless messages by detecting valid and authorized signal pilots, determining the angle of arrival, and spatially filtering messages to discard those from unauthorized sources, thereby ensuring only messages from trusted vehicles within the platoon are considered authentic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If direct vehicle-to-vehicle messages are used for coordinated driving, then communication efficiency is improved, but security against malicious actors deteriorates
Solution Approach 1:
The patent introduces signal pilots as intermediary elements that mediate between the transmitting and receiving vehicles. These pilots serve as verifiable markers that allow receiving vehicles to authenticate messages without compromising communication efficiency. The signal pilots act as a trusted intermediary that proves the origin of messages while maintaining the direct V2V communication channel.
Solution Approach 2:
The patent implements preliminary authentication by verifying signal pilots before processing message content. receiving vehicles perform authenticity checks on the signal pilots embedded in messages before accepting or acting upon the message data. This preliminary verification prevents malicious messages from being processed, thereby maintaining security while preserving efficient communication for authentic messages.
2Reliability
If signal pilots are used to authenticate messages, then message authenticity is improved, but device complexity increases
Solution Approach 1:
The patent makes the signal pilots multi-functional by using them for both communication purposes (carrying message data) and authentication purposes (verifying message origin). This universal use of signal pilots avoids the need for separate authentication mechanisms, thereby improving message authenticity without proportionally increasing device complexity. The same pilot signals serve dual functions, reducing overall system complexity.
3Reliability
If spatial filtering is applied to detect angle of arrival, then security against malicious messages is improved, but measurement precision requirements increase
Solution Approach 1:
The patent implements feedback mechanisms where receiving vehicles continuously monitor and compare the angle of arrival of signal pilots against expected angular positions of platoon members. This feedback loop allows the system to adapt to minor measurement variations while maintaining security. The feedback mechanism tolerates small measurement imprecisions by comparing against dynamically updated expected positions, thereby maintaining security without requiring extremely high measurement precision.
