Radar Signal Authentication via Embedded Identity Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle-to-vehicle (V2V) communication, there is a need to verify the authenticity of information received through radar signals to prevent malicious or malfunctioning entities from sending invalid information, which could lead to unsafe vehicle behavior.
Innovation Solution
A method and apparatus that combine radar systems with V2X communication, where the authenticity of embedded information is determined by comparing the position of the sender of the radar signal with the position associated with the embedded information, using reception characteristics and environment mapping techniques, to authenticate the sender and ensure the validity of the information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If radar signals are used for V2V communication, then communication range and penetration capability are improved, but authentication reliability deteriorates due to inability to verify sender identity
Solution Approach 1:
The patent combines radar signal reception with identity authentication by integrating the radar receiver with an authentication module that extracts and verifies identity information from the radar signal itself, merging communication and authentication functions into a single system
Solution Approach 2:
The patent uses an authentication module as an intermediary that processes the radar signal to extract identity information and compare it with stored reference data, acting as a mediator between the radar receiver and the decision-making system
2Measurement precision
If position comparison is used for authentication, then sender verification accuracy is improved, but system complexity increases due to additional processing requirements
Solution Approach 1:
The radar system is designed to serve multiple functions simultaneously: it performs both environmental sensing and identity authentication by extracting position information from the same radar signal used for collision detection, eliminating the need for separate authentication hardware
Solution Approach 2:
The radar signal itself contains the position information needed for authentication, allowing the system to authenticate senders using information already present in the communication signal without requiring additional external references or complex verification infrastructure
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach effectively verifies the authenticity of information received, increasing trust in valid senders and reducing the risk of unsafe behavior caused by invalid information, thereby enhancing safety in intelligent transportation systems.
Implementation Method 1
a radar system which can map the environment surrounding the vehicle. These radar systems may be useful for collision prevention.
Implementation Method 2
determining the first position in dependence on reception characteristics of the radar signal. Determining the first position may comprise processing the radar signal using a radar algorithm.

AI summary
A method and apparatus are provided. A radar signal comprising first identity information is received. Information on a non-radar channel comprising second identity information is received. It is determined that the radar signal and the information on the non-radar channel are sent from a first sender when the first and second identity information correspond.
