The sixth generation (6G) networks are expected to provide a fully connected world with terrestrial wireless and satellite communications integration. The design concept of 6G networks is to leverage artificial intelligence (Ai) to promote the intelligent and agile development of network services. intelligent services inevitably involve the processing of large amounts of data, such as storage, computing, and analysis, such that the data may be vulnerable to tampering or contamination by attackers. in this article, we propose a blockchain-based data security scheme for Ai applications in 6G networks. Specifically, we first introduce the 6G architecture (i.e., a space-air-ground-underwater integrated network). Then we discuss two Ai-enabled applications, indoor positioning and autonomous vehicle, in the context of 6G. Through a case study of an indoor navigation system, we demonstrate the effectiveness of blockchain in data security. The integration of Ai and blockchain is developed to evaluate and optimize the quality of intelligent service. Finally, we discuss several open issues about data security in the upcoming 6G networks.

基于区块链的6G网络人工智能应用数据安全

第六代（6G）网络有望为地面无线和卫星通信集成提供一个完全连接的世界。6G网络的设计概念是利用人工智能（Ai）来促进网络服务的智能和敏捷发展。智能服务不可避免地涉及大量数据的处理，例如存储，计算和分析，因此数据可能容易受到攻击者的篡改或污染。在本文中，我们为6G网络中的Ai应用提出了一种基于区块链的数据安全方案。具体来说，我们首先介绍6G架构（即空空地水下一体化网络）。然后，我们在6G的背景下讨论两种支持Ai的应用，即室内定位和自动驾驶汽车。通过室内导航系统的案例研究，我们证明了区块链在数据安全中的有效性。开发Ai和区块链的集成是为了评估和优化智能服务的质量。最后，我们讨论了即将到来的6G网络中有关数据安全性的几个未解决的问题。
