摘要：
自然灾害发生后，地面基础设施遭到破坏，应急通信至关重要但极具挑战性。无人机（UAV）在这些场景中为敏捷救援协调提供了巨大潜力。然而，有效利用无人机机队还带来了安全、隐私以及跨响应机构高效协作方面的额外挑战。本文提出了一个稳健的区块链赋能框架，通过整合联盟区块链模型、智能合约和密码学技术来安全地协调无人机机队进行灾难响应，以应对这些挑战。具体而言，我们做出了两项关键贡献：一个用于安全且隐私保护的多机构协调的联盟区块链架构；以及一个使用委托权益证明实用拜占庭容错（DPoS-PBFT）的优化共识协议，在效率和容错性之间取得平衡。全面的仿真展示了该框架在灾后网络中增强无人机协调的透明度、自动化、可扩展性和网络攻击韧性的能力。
英文摘要：
Emergency communication is critical but challenging after natural disasters when ground infrastructure is devastated. Unmanned aerial vehicles (UAVs) offer enormous potential for agile relief coordination in these scenarios. However, effectively leveraging UAV fleets poses additional challenges around security, privacy, and efficient collaboration across response agencies. This paper presents a robust blockchain-enabled framework to address these challenges by integrating a consortium blockchain model, smart contracts, and cryptographic techniques to securely coordinate UAV fleets for disaster response. Specifically, we make two key contributions: a consortium blockchain architecture for secure and private multi-agency coordination; and an optimized consensus protocol balancing efficiency and fault tolerance using a delegated proof of stake practical byzantine fault tolerance (DPoS-PBFT). Comprehensive simulations showcase the framework's ability to enhance transparency, automation, scalability, and cyber-attack resilience for UAV coordination in post-disaster networks.
