UAV-Undertaker: Securely Verifiable Remote Erasure Scheme with a Countdown-Concept for UAV via Randomized Data Synchronization

Figure 2

Overall process of the proposed remote erasure system. (a) Unmanned aerial vehicle (UAV)-Undertaker from the Ground Control Station (GCS) viewpoint; (b) UAV-Undertaker from the UAV viewpoint. If the count value becomes zero, the UAV erases data and repeatedly sends the proof of erasure to the user (i.e., the GCS).
