A Secure LiDAR with AES-Based Side-Channel Fingerprinting

摘要

Sensor spoofing attack is an emerging threat to laser-based ranging. In this paper, we propose a countermeasure that superimposes authentication fingerprint onto light wave itself. In the proposed method, amplification of laser output is directly modulated by power side-channel information leaked from a cryptographic device. The feasibility of the concept is verified through experiments.
