Blockchain-Based Heuristic Study to Secure UAVs From GPS Spoofing Signals and External Attacks

This paper presents a heuristic study to introduce the use of blockchain technology for securing Unmanned Aerial Vehicle Systems (UAVs) against security threats, for example Global Positioning System (GPS) spoofing and improving their efficiency. We leverage a unique combination of “Write Once, Read Many (WORM),” and “Multi-Factor Authentication (MFA)” to create a fortified security infrastructure. Our code results validate the robustness of this combined approach, demonstrating its superiority in providing enhanced protection against data tampering and unauthorised access. The study concludes by contrasting the stand-alone WORM technique with the synergistic WORM+MFA method, evaluating them on key metrics such as level of security, cost of implementation, and user convenience to secure UAVs from GPS spoofing signals and external attacks.
