5G-enabled drones have potential applications in a variety of both military and civilian settings (e.g., monitoring and tracking of individuals in demonstrations and/or enforcing of social/ physical distancing during pandemics such as COVID-19). Such applications generally involve the collection and dissemination of (massive) data from the drones to remote data centers for storage and analysis (e.g., via 5G networks). Consequently, there are security and privacy considerations underpinning 5G-enabled drone communications. We posit the potential of leveraging blockchain to facilitate privacy preservation, and therefore in this article we review existing blockchain-based solutions after introducing the architecture for 5G-enabled drone communications and block-chain. We also review existing legislation and data privacy regulations that need to be considered in the design of blockchain-based solutions, as well as identify potential challenges and open issues that will hopefully inform future research.

基于区块链的 5G 无人机通信隐私保护


支持 5G 的无人机在各种军事和民用环境中都有潜在应用（例如，监控和跟踪示威中的个人和/或在 COVID-19 等流行病期间强制执行社交/物理距离）。此类应用通常涉及从无人机收集（大量）数据并将其传播到远程数据中心以进行存储和分析（例如，通过 5G 网络）。因此，支持 5G 的无人机通信需要考虑安全和隐私问题。我们认为利用区块链来促进隐私保护的潜力，因此在本文中，我们在介绍支持 5G 的无人机通信和区块链的架构后，回顾了现有的基于区块链的解决方案。我们还审查了在设计基于区块链的解决方案时需要考虑的现有立法和数据隐私法规，并确定了潜在的挑战和未解决的问题，希望能为未来的研究提供信息。
