LiDAR, essential for autonomous driving, is vulnerable to "spoofing attacks" that inject fake laser pulses to cause obstacle misperception. This paper proposes the world's first dToF LiDAR SoC capable of defending against this threat. The system utilizes "Dual-Domain Fingerprinting (DDF)" to eliminate fake signals by authenticating received pulses based on both time and amplitude information. Furthermore, an "Event-Driven AFE (ED-AFE)" activates the ADC only during pulse waveform peaks, reducing power consumption. Evaluation results show a ranging capability of up to 80m under 100,000lux, successfully protecting 73% of the point cloud under attack while reducing AFE power consumption by 60% compared to conventional techniques. |
