V2X Misbehavior in Maneuver Sharing and Coordination Service: Considerations for Standardization

TL;DR

This paper examines security vulnerabilities in V2X communication, specifically in Maneuver Sharing and Coordination Service, highlighting the need for standardized misbehavior detection to enhance CAV safety.

Contribution

It assesses security issues in MSC Messages and offers recommendations for including misbehavior specifications in V2X standardization efforts.

Findings

V2X communication is vulnerable to false data injection attacks.

Current standards lack misbehavior detection for advanced V2X services.

Recommendations for standardization considerations are proposed.

Abstract

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