Sentinel-V2X
INTRUSION DETECTION AND PREVENTION FOR CONNECTED AND AUTOMATED VEHICLESnetwork
Vehicle-to-everything (V2X) technologies are a key component in the future development of highly automated driving systems. And while V2X communication methods provide channel security that limits direct intrusion, they do not provide message content inspection for attacks from compromised devices.
Arilou’s Sentinel-V2X mitigates this problem by combining deep content inspection (DCI) with misbehavior detection (MD) and sensor fusion. This ensures that received messages are in line with baseline expectations and other sources of vehicle data.

Detect violations of established baseline or expected behaviorReport
Report and log detected cyber-events for further analysisDiscard
Discard events that are hazardous to safety or functionality
INTEGRATION ARCHITECTUREintegration
Sentinel-V2X is an SDK that can be integrated into the Onboard Unit (OBU) or nearby. Configurable as both an intrusion detection (IDS) and optional intrusion prevention system (IPS).
Incoming V2X messages are routed to Sentinel-V2X
Messages are inspected and any anomaly is reported.
When configured as an IPS, messages hazardous to safety or functionality are discarded.
Arilou offers flexible implementation modes tailored to meet OEM needs and architectural environments.
