为了应对6G因不同于传统蜂窝移动通信的网络节点数量巨大、异构节点组成复杂、网络环境立体开放、网络组织和运行全智能化而带来的通信安全挑战,研究了具有类量子安全特点的物理层安全技术,为6G通信提供安全保障。通过研究分析表明,在6G通信中使用物理层安全技术可降低身份认证和保密传输的实现复杂度,且能利用6G通信的终端设备和无线环境提供的唯一性及随机性特征实现较高的安全性,特别是对于未来的海量终端连接和海量数据传输,具有类量子特征的物理层安全技术提供了轻量化和高可靠的安全方案。

The sixth-generation(6G) mobile communication network is different from the traditional cellular mobile communication in terms of massive network nodes, a complex composition of heterogeneous nodes, a three-dimensional open network environment, and a fully intelligent network organization and operation. In order to cope with communication security challenges caused by the above difference, this paper investigates s the physical layer security technology with quasi quantum security characteristics to provide a security guarantee for 6G communication. Research and analysis show that using physical layer security technology in 6G communication can reduce the implementation complexity of identity authentication and secrecy transmission, and can make use of the uniqueness and randomness provided by the terminal equipment and wireless environment of 6G communication to achieve high security of the system. The physical layer security technology with quasi quantum characteristics can provide a lightweight and highly reliable security solution for 6G technology, especially for the future massive terminal connection and massive data transmission.
