Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If V2X communication is used for autonomous driving, then information sharing and coordination between vehicles is improved, but vulnerability to malicious attacks and misbehavior increases
Solution Approach 1:
The system performs preliminary validation of V2X messages by checking digital signatures and certificates before processing the information content. This preliminary security check ensures that only authenticated messages from trusted sources are accepted, preventing malicious attacks while maintaining information sharing capabilities.
Solution Approach 2:
The patent introduces an intermediary verification layer that mediates between V2X message transmission and autonomous driving decision-making. This intermediary validates message authenticity through cryptographic verification and cross-checks information consistency across multiple sources before the information is used for driving decisions.
2Reliability
If misbehavior detection systems are implemented, then security and reliability are improved, but system complexity and computational overhead increase
Solution Approach 1:
The misbehavior detection system is segmented into distinct functional modules: digital signature verification, certificate validation, information consistency checking, and anomaly detection. Each module handles a specific aspect of security verification, making the overall complex system manageable and maintainable while providing comprehensive security.
Solution Approach 2:
The system performs self-verification by checking the authenticity of received messages using embedded cryptographic verification capabilities. Each autonomous vehicle independently validates V2X messages without requiring external arbitration, reducing system complexity while maintaining high security standards.
3Measurement precision
If comprehensive message analysis is performed to detect anomalies, then detection precision is improved, but processing time and computational resources increase
Solution Approach 1:
The system performs preliminary filtering of V2X messages based on basic validity criteria such as digital signature verification and format checking before conducting more intensive anomaly detection analysis. This preliminary action discards obviously invalid messages early, reducing the computational burden on the precision detection algorithms.
Solution Approach 2:
The patent applies partial analysis to routine messages that appear normal, performing only essential validation checks. Excessive or full-depth analysis is reserved for messages that exhibit suspicious characteristics or come from untrusted sources, optimizing the balance between detection precision and processing time.
Data Source
AI summary
A first roadway system receives a communication from a second roadway system over a wireless channel, where the communication includes a description of a physical object within a driving environment. Characteristics of the physical object are determined based on sensors of the first roadway system. The communication is determined to contain an anomaly based on a comparison of the description of the physical object with the characteristics determined based on the sensors of the first roadway system. Misbehavior data is generated to describe the anomaly. A remedial action is initiated based on the anomaly.
