Autonomous fleets rely on V2V (Vehicle-to-Vehicle) messages to drive in tight formations. Drift Systems injects a rolling "Physics Proof" into every braking command, ensuring that spoofed signals from roadside attackers are mathematically rejected.
Three trucks are platooning. The Leader sets the pace. An attacker tries to inject a "HARD BRAKE" command to the middle truck to cause a pile-up. Watch how the Drift Core validates the message lineage.
Drift Defense: The spoofed command has a valid format but an invalid Drift Sequence ($S_{fake} \neq F(S_{last})$). The truck's ECU rejects the brake command and switches to "Safe Degrade" mode (slow deceleration) instead of slamming the brakes.
Standard ECDSA signatures are too slow for millisecond-critical braking decisions. Drift provides a lightweight "Hot Check" envelope that validates message origin in 1 clock cycle, filtering attacks before the main CPU parses them.
In tunnels or urban canyons where GPS fails, Drift provides a relative "Clockless" synchronization heartbeat. Vehicles maintain formation based on sequence counts rather than absolute UTC time.
Smart intersections broadcast signal phases. Drift prevents attackers from triggering "All Green" lights by binding the signal controller's state to a rolling drift chain that cannot be replayed or forged.
In the event of a crash, the Drift Log provides an immutable record of exactly what commands were received and in what order. This mathematical audit trail is crucial for insurance and liability in autonomous systems.
