5G and beyond (B5G) networks significantly promote the popularity and ubiquity of drones by providing high-throughput and low-latency communication. In B5G drone networks, data sharing among drones has great potential to improve and enrich civilian and commercial applications, such as surveillance monitoring. Nevertheless, a series of security challenges arise such as data privacy leakage due to the lack of reliable centralized supervision. In this article, we employ the permissioned blockchain technology to propose a decentralized data management system. The permissioned blockchain deployed at pre-selected ground base stations is particularly suitable and practical for ensuring efficient peer-to-peer data sharing in B5G drone networks. However, the ground base stations working as miners are widely deployed without strong security protection, which may be compromised to produce maliciously manipulated results during the block verification in the permissioned blockchain. Hence, the miner selection is crucial for the permissioned blockchain-based B5G drone networks. We therefore introduce credit as a metric and propose a secure credit-based miner selection scheme using a four-weight subjective logic model. Numerical results demonstrate that the proposed schemes are effective for secure data sharing in permissioned blockchain-based B5G drone networks.

确保空中数据共享的安全：将区块链集成到 5G 及其他领域的无人机中


5G 及更高版本 (B5G) 网络通过提供高吞吐量和低延迟通信，显着促进了无人机的普及和普及。在B5G无人机网络中，无人机之间的数据共享具有改善和丰富民用和商业应用（例如监视监控）的巨大潜力。然而，由于缺乏可靠的集中监管，出现了数据隐私泄露等一系列安全挑战。在本文中，我们采用许可的区块链技术提出了一个去中心化的数据管理系统。部署在预先选定的地面基站上的许可区块链特别适合且实用，可确保 B5G 无人机网络中高效的点对点数据共享。然而，作为矿工工作的地面基站广泛部署，缺乏强大的安全防护，在许可的区块链中进行区块验证时，可能会受到损害，产生恶意操纵的结果。因此，矿工的选择对于基于许可的区块链 B5G 无人机网络至关重要。因此，我们引入信用作为衡量标准，并使用四权重主观逻辑模型提出一种基于信用的安全矿工选择方案。数值结果表明，所提出的方案对于基于许可的区块链 B5G 无人机网络中的安全数据共享是有效的。
