Abstract

Recent revolutionary advancements in the services as observed with the use cases of Industry 5.0, consumer electronics 2.0/smart devices 2.0, digital healthcare ecosystem, Internet-of-Things (IoT), advanced digital finance/currency, and Non-Terrestrial Network (NTN) expansion, to name a few, have resulted in a spectacular growth in the number of wireless-connected devices. Subsequently, this has drastically increased the demands for network capacity, channel capacity, reliability, privacy, and security provisions. Despite that, the 5th Generation (5G) of wireless communication networks has introduced various innovative services such as Ultra-Reliable Low Latency Communication (URLLCs), Massive Machine Type Communication (mMTCs), and Enhanced Mobile Broadband (eMBB). These services only support isolated operations and the requisite reliable service delivery remains a challenge. The Beyond 5G (B5G)/6th Generation (6G) wireless networks aim at simultaneously providing multiple integrated services through intelligent network operations with ultra-high speed and reliability supporting integrated NTN and terrestrial networks. However, the prospect of such an extensively connected decentralized 3D wireless network also foresees security concerns, underscoring the necessity for seamless and infrastructure-free (decentralized) security solutions. The conventional security mechanisms are considered inadequate to ensure the security provisions of such extensive, decentralized, and heterogeneous networks. Physical Layer Security (PLS) is a promising technique to extend seamless and infrastructure-less security solutions, ensuring the availability, confidentiality, and integrity of legitimate transmissions. This paper provides a comprehensive overview with tutorials and presents the state-of-the-art of PLS, focusing mainly on NTN wireless communications. Furthermore, current research challenges, open issues, and future research directions are also thoroughly discussed in an amalgamation of various emerging 6G technologies. Finally, we provide an overview of implementation challenges in NTN and potential solutions to support the standardization progression of NTN in upcoming releases of 3rd Generation Partnership Project (3GPP).
下一代非地面无线网络中无人机和物理层安全的需求:潜在挑战和开放问题
从工业5.0、消费电子2.0/智能设备2.0、数字医疗生态系统、物联网(IoT)、高级数字金融/货币和非地面网络(NTN)扩展等用例来看,最近服务领域的革命性进步导致了无线连接设备数量的惊人增长。随后,这大大增加了对网络容量、通道容量、可靠性、隐私和安全规定的需求。尽管如此,第5代(5G)无线通信网络引入了各种创新服务,如超可靠低延迟通信(urllc)、大规模机器类型通信(mmtc)和增强型移动宽带(eMBB)。这些服务只支持孤立的操作,所需的可靠服务交付仍然是一个挑战。超5G (B5G)/ 6G (sixth Generation)无线网络旨在通过超高速、高可靠性的智能网络运营,同时提供多种综合业务,支持NTN和地面网络的融合。然而,这种广泛连接的分散式3D无线网络的前景也预示着安全问题,强调了无缝和无基础设施(分散式)安全解决方案的必要性。传统的安全机制被认为不足以确保如此广泛、分散和异构网络的安全规定。物理层安全(PLS)是一种很有前途的技术,可以扩展无缝和无基础设施的安全解决方案,确保合法传输的可用性、机密性和完整性。本文提供了一个全面的概述与教程,并提出了最先进的PLS,主要集中在NTN无线通信。此外,还在各种新兴6G技术的融合中深入讨论了当前的研究挑战、开放问题和未来的研究方向。最后,我们概述了NTN的实施挑战,以及在即将发布的第三代合作伙伴计划(3GPP)中支持NTN标准化进程的潜在解决方案。
