V2X Misbehavior and Collective Perception Service: Considerations for Standardization

TL;DR

This paper examines security vulnerabilities in V2X communication, especially collective perception services, highlighting the need for standardized misbehavior detection to enhance CAV safety.

Contribution

It assesses the security of Collective Perception Messages and provides inputs for standardization efforts to address misbehavior in V2X systems.

Findings

Current standards lack misbehavior specifications for advanced V2X services.

Assessment reveals vulnerabilities in Collective Perception Messages.

Recommendations for including misbehavior detection in standards.

Abstract

Connected and Automated Vehicles use sensors and wireless communication to improve road safety and efficiency. However, attackers may target Vehicle-to-Everything communication. Indeed, an attacker may send authenticated but wrong data to send false location information, alert incorrect events or report a bogus object endangering the safety of other CAVs. Currently, Standardization Development Organizations are working on developing security standards against such attacks. Unfortunately, current standardization efforts do not include misbehavior specifications for advanced V2X services such as Collective Perception yet. This work assesses the security of Collective Perception Messages and proposes inputs for consideration in existing standards.
