“…The authors considered a fixed terminal LTE setup and discussed security issues around trusted domainbased and IPsec VPN-based backhaul architectures. Kaloxylos et al [21] focused on the session and mobility management in SDN-enabled 5G networks. The authors explored the 5G security functions of the 3GPP and suggested the methodologies for including SDN in 5G to increase the performance in the densification of the network.…”

With the evolution of wireless technologies, 5G and Beyond (5GB) communication is paving a way for efficient, ultrareliable, low-latent, and high converging services for the Internet of Things (IoT). Along with efficient communication, the security of messages is one of the concerns which must be maintained throughout the operations. Backhaul forms an essential part of 5GB with an ability to enhance the coverage and quality of service for IoT. However, conventional wired backhaul connection would cost operators thousands of dollars in the construction of 5GB infrastructure considering the ultra-dense nature of IoT. As a result, wireless backhaul is quickly becoming a feasible alternative to address 5GB's direction towards network densification without affecting its other provisions. Wireless backhaul is expected to increase the landscape, covering from islands to mountains, which were difficult to access in the existing network generation. Moreover, it can effectively respond to the situation where the data traffic tremendously increased. Despite such provisioning, the wireless backhaul poses relatively various security threats and vulnerabilities due to the characteristics of wireless technologies. Several studies have been conducted to address the security problems; however, existing protocols do not support dynamic security policy and key management in a decentralized structure as well as secure handover in a specific scenario where Terminals (TMs) are moving. Motivated by this, we proposed the Mobile Terminal Handover Security Protocol (MoTH) to provide secure handover of mobile terminals between hubs. To solve the problem of existing protocols, a new entity called Backhaul Management Function (BMF) is introduced to support distributed and dynamic security policy and key management in each serving network of 5GB backhaul environment. The proposed protocol satisfies security requirements including authentication and key management, confidentiality, integrity, and perfect forward secrecy. Additionally, it supports policy and key update services, and optimized handover. The security and correctness of the proposed protocol are thoroughly verified using the two formal security analysis tools, BAN logic and Scyther. Additionally, the performance evaluation shows that the proposed protocol is efficient.

“…To discover an idle MN's current location, the location area's cells are contacted through paging. With the upcoming densification of 5G, it is expected that there will be a considerable increase in location management signaling costs due to the increase in location updates (if the tracking areas are small) or paging (if the tracking areas are large) [35].…”

Future integrated terrestrial, aerial, and space networks will involve thousands of low-Earth-orbit (LEO) satellites, which will form a network of mega-constellations. These megaconstellations will play a significant role in providing communication and Internet services anywhere, at any time, and for everything. Due to the large scale and highly dynamic nature of future LEO satellite networks (SatNets), their management will be a complicated process, especially the aspect of mobility management and its two components: location management and handover management. In this article, we present a comprehensive and critical review of the state-of-the-art research in location management for LEO SatNets. First, we give an overview of the Internet Engineering Task Force (IETF) mobility management standards (e.g., Mobile IPv6 and Proxy Mobile IPv6) and discuss the limitations of their location management techniques for future LEO SatNets. We highlight the mobility characteristics of future LEO SatNets and their challenging features, and we describe two unprecedented future location management scenarios. A taxonomy of existing location management solutions for LEO SatNets is also presented with solutions classified according to three approaches. The "Issues to consider" section draws attention to critical points related to each of the reviewed approaches that should be considered in future LEO SatNets location management. To identify the research gaps, the current state of LEO SatNets location management is summarized. Noteworthy future research directions are recommended. The article provides a road map for researchers and industry to shape the future of location management for LEO SatNets.
