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.

基于区块链的隐私保护，支持5G无人机通信

支持5G的无人机在各种军事和民用环境中都有潜在的应用（例如，在示范中监视和跟踪个人，和/或在大流行期间（例如COVID-19）强制执行社交/身体疏离）。此类应用通常涉及从无人机收集（大量）数据并将其分发到远程数据中心，以进行存储和分析（例如，通过5G网络）。因此，在支持5G的无人机通信中有一些安全和隐私方面的考虑。我们具有利用区块链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。
