- Formal analysis of an authority transfer protocol for UAVsPublication . Rodrigues, Ricardo Alexandre Almeida; Pereira, David Miguel RamalhoThe use of Unmanned Aerial Vehicles (UAVs) in a variety of applications has resulted in a growing demand for Beyond Visual Line of Sight (BVLOS) operations to cover long distances. This thesis focuses on an initial analysis of a UAV communication protocol designed for transferring control authority between ground controls within a common range, addressing challenges and evaluating its efficacy across different operational phases. The research encompasses start-up, mission execution, and handover phases, assessing the protocol’s interactions with ground-based systems for reliability, efficiency, and adaptability. A comprehensive overview of model checking is provided, emphasizing transition systems, formalisms, and tools for system correctness verification. The research employs model checking to formally specify and model the UAV communication protocol, establishing evaluation criteria through the use of LTL and CTL properties. The derived requirements serve as a foundational framework for future iterations, ensuring the protocol’s robustness and addressing security strategies in the event of connection loss. The holistic approach contributes to a comprehensive understanding of the protocol’s functionality, aiming to enhance the security authorization handover procedure and promote public and regulatory acceptance of BVLOS operations with UAVs.
