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 centres for storage and analysis, for example 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 will review existing blockchain-based solutions after introducing the architecture for 5G-enabled drone communications and blockchain. We will also review existing legislation and data privacy regulations that need to be considered in the design of blockchain-based solutions, as well as identifying potential challenges and open issues which will hopefully inform future research agenda.

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的应用（例如，监视和跟踪演示中的个人和/或在 COVID-19 等大流行期间加强社会/物理距离）。此类应用通常涉及从无人机到远程数据中心的（大量）数据的收集和传播，以进行存储和分析，例如通过 5G 网络。因此，支持 5G 的无人机通信存在安全和隐私方面的考虑。我们假设利用区块链促进隐私保护的潜力，因此在本文中，我们将在介绍支持 5G 的无人机通信和区块链架构后回顾现有的基于区块链的解决方案。
