Un-Rocking Drones: Foundations of Acoustic Injection Attacks and Recovery Thereof
Jinseob Jeong (KAIST, Agency for Defense Development), Dongkwan Kim (Samsung SDS), Joonha Jang (KAIST), Juhwan Noh (KAIST), Changhun Song (KAIST) and Yongdae Kim (KAIST) discovered that sampling jitter, which refers to the inconsistent timing delay in retrieving sensor values, has a significant impact on drone crashes during the attack. Note that while any real-time system needs to satisfy its real-time requirements, it does have sampling jitter owing to manufacturing errors or scheduling/operational overheads. The sampling jitter is negligible in terms of real-time requirements; however, we found that it became critical for drones being attacked.
