Misbehavior Report Router for V2X OEM Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-to-everything (V2X) systems face challenges in routing misbehavior detection reports to the appropriate original equipment manufacturer (OEM) due to privacy protections and lack of mechanisms for identifying the misbehaving V2X onboard equipment, which hinders corrective actions and maintenance.
Innovation Solution
Implementing a Misbehavior Report Router (MRR) function within certificate provisioning authorities and storing information during certificate issuance to enable routing of misbehavior detection reports to the OEM, using pseudonym certificate information and Certificate Signing Request identifiers to identify the misbehaving equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If privacy protections are implemented in V2X systems, then individual privacy is protected, but the ability to identify misbehaving equipment for corrective actions is hindered
Solution Approach 1:
The system segments identification information into two parts: pseudonym certificates for public use that protect privacy, and unique identifiers stored securely in the MRR that enable precise identification. This segmentation allows the system to maintain both privacy protection and identification capability simultaneously.
Solution Approach 2:
The Misbehavior Report Router acts as an intermediary that receives misbehavior reports containing pseudonym certificates, looks up the corresponding unique identifiers using the certificate information, and routes the reports to the appropriate OEM. This intermediary function bridges the gap between privacy-protected pseudonyms and unique identification requirements.
2Ease of repair
If misbehavior detection reports are routed to the responsible OEM, then corrective actions can be taken, but the system complexity increases due to routing infrastructure requirements
Solution Approach 1:
The Misbehavior Report Router is designed with multi-functionality: it performs certificate validation, identifier lookup, report routing, and logging functions all in one component. This consolidation reduces overall system complexity compared to having separate systems for each function.
Solution Approach 2:
The system performs preliminary actions by pre-storing the mapping between pseudonym certificates and unique identifiers in the MRR during certificate provisioning. This preliminary setup eliminates the need for complex real-time identification queries when misbehavior reports are generated, simplifying the routing process.
3Measurement precision
If pseudonym certificate information is stored in MRR during certificate provisioning, then routing accuracy is improved, but information storage requirements increase
Solution Approach 1:
The system applies local quality by storing different types of information in different locations: pseudonym certificates are stored in the MRR for routing purposes, while unique identifiers are stored securely in the certificate provisioning system. Each location stores only the information it needs, optimizing storage efficiency.

AI summary
Methods, devices, non-transitory processor-readable media of various embodiments provide for routing Misbehavior Detection Reports from vehicle-to-everything (V2X) onboard equipment to an associated entity. Various embodiments may include storing, within a Misbehavior Report Router resulting from provisioning of a certificate to a V2X onboard equipment, information that enables a Misbehavior Detection Report to be routed to the entity associated with misbehaving V2X onboard equipment, examining a Misbehavior Detection Report received from a reporting V2X onboard equipment to identify a Pseudonym Certificate Authority Misbehavior Report Router of the entity associated with misbehaving V2X onboard equipment, passing the Misbehavior Detection Report to the identified Pseudonym Certificate Authority Misbehavior Report Router, using information in the Misbehavior Detection Report with information stored in the Pseudonym Certificate Authority Misbehavior Report Router to route the Misbehavior Detection Report to the associated entity.
