Security in5Gand beyond recent advances and future challenges

Abstract

5G, 6G, and beyond (xG) technologies aim at delivering emerging services with new requirements and challenges, enabling full and hyper mobile connectivity over the world. These beyond 5G networks are expected to ensure better quality of service, very high data rate, improved network security, high capacity, low latency, and low cost. In order to meet these objectives, a number of key enabler technologies have been proposed including massive multiple input multiple output, small cells, mobile edge computing, software defined network, network function virtualization, heterogeneous networks, network slicing, cloud radio access network, ultra-dense network, energy efficiency, and spectrum sharing. Although, the potential interest of these technologies in the network, they opened the door to many security concerns and challenges making the network security one of the primary concerns of the future wireless communication networks. In this article, we investigated the recent advancements on the xG security issues resulted by each key enabler technologies. We analyzed how to secure the network while meeting the emerging promising services, users' demands, and service requirements. We also discussed how the security issues raised by these emerging technologies can be mitigated for efficient and secure communication.

The quantum internet: A synergy of quantum information technologies and 6G networks

“…Globally, scientists are conducting fundamental research and development in the disciplines of 6G and quantum technology [138]. Quantum computers will have demonstrated ‘quantum supremacy’ over classical computers in specific tasks by 2025, but they are not yet commercially viable [139].…”

Security and Privacy for Low Power IoT Devices on 5G and Beyond Networks: Challenges and Future Directions

“…Many of the scrutinised articles focus on adding protective layers, such as ML, without fully addressing all IoT characteristics and the three basic principles of security which are confidentiality, integrity and availability concurrently [8]. While recent studies, such as those conducted by the authors in [9] and [10] explore the use of emerging technologies and threats, human-centric issues and the mechanisms that lead to data exploitation through legitimate means are not investigated. Consequently, the preliminary investigation has identified the following issues related to cyber security vulnerabilities surrounding IoT data privacy concerns.…”

“…A particular challenge in securing IoT devices on 5GBN is compliance with different standards across jurisdictions for devices that can have a global reach [139], [140]. While the authors investigate the introduction of regulations to enhance 5G and beyond network security [9], previous research has illustrated several challenges of this approach. As identified by [139], [140] and [141], ensuring that the data that IoT devices collect and transmit meets all regulatory requirements is challenging.…”

Quality of Service and Associated Communication Infrastructure for Electric Vehicles

“…This research article explores challenges in 5G-based vehicular communication, including the use of heterogeneous and small cell networks, millimeter-wave communication, massive multiple-input, multipleoutput (MIMO) networks, vehicular cloud and fog computing, SDNs, mobile edge computing, network slicing, and dynamic spectrum sharing. The article offers solutions to these challenges and suggests future research directions for vehicular communication [113,114].…”
