“…and M (21) 10 ). In the proposed protocol, it is difficult for the intrusion IoT device to obtain authentication samples because cryptography-based authentication is performed selectively with low probability (Section IV.B), which means that the proposed protocol is secure against other intelligent attacks (e.g., replay and DoS attacks) for cryptography-based authentication.…”

“…Alternatively, physical layer authentication (PLA), which enables fast and lightweight authentication by exploiting physical characteristics (e.g., channel, and carrier frequency offset (CFO)) for authentication, has attracted attention as an authentication solution for IoT devices due to its efficiency and effectiveness [20], [21]. PLA can be divided into two cases, i.e., PLA without a shared PHY secret key and PLA with a shared PHY secret key, according to the purpose of the exploited physical layer (PHY) features.…”

An innovative cross-layer authentication protocol that integrates cryptography-based authentication and physical layer authentication (PLA) is proposed for massive cellular Internet of things (IoT) systems. Due to dramatic increases in the number of cellular IoT devices, a centralized authentication architecture in which a mobility management entity in core networks administers authentication of massive numbers of IoT devices may cause network congestion with large signaling overhead. Thus, a distributed authentication architecture in which a base station in radio access networks authenticates IoT devices locally is presented. In addition, a cross-layer authentication protocol is designed with a novel integration strategy under the distributed authentication architecture, where PLA, which employs physical features for authentication, is used as preemptive authentication in the proposed protocol. Theoretical analysis and numerical simulations were performed to analyze the trade-off between authentication performance and overhead in the proposed authentication method compared with existing authentication protocols. The results demonstrate that the proposed protocol outperforms conventional authentication and key agreement protocols in terms of overhead and computational complexity while guaranteeing low authentication error probability.

“…On the other hand, enabling network slicing for multiple tenants with distinct requirements using a wide variety of physical infrastructures through SDN and NFV involves different networks. Enabling network slicing suffers from serious security concerns, including multi-domain security, such as edge computing security [64], cloud security [65], telecommunication networks security, and IoT networks security [66].…”

Fifth-generation (5G) and beyond networks are envisioned to provide multi-services with diverse specifications. Network slicing is identified as a key enabling technology to enable 5G networks with multi-services. Network slicing allows a transition from a network-as-an-infrastructure setup to a networkas-a-service to enable numerous 5G smart services with diverse requirements. Although several surveys and tutorials have discussed network slicing in detail, there is no comprehensive study discussing the taxonomy and requirements of network slicing. In this paper, we present and investigate key recent advances of network slicing towards enabling several Internet of Things (IoT) smart applications. A taxonomy is devised for network slicing using different parameters: key design principles, enablers, slicing resources levels, service function chaining schemes, physical infrastructures, and security. Furthermore, we discuss key requirements for network slicing to enable smart services. Finally, we present several open research challenges along with possible guidelines for network slicing.

“…Security solutions for 5G networks at physical layer are probably the most reported technologies. Although, as previously said, most works are analyzing the security threats, challenges and opportunities [ 44 , 45 , 46 ]; some specific technologies have been reported. In particular, technologies based on different channel estimators to prevent spoofing attacks in the wireless media have been described [ 47 ].…”

Future 5G networks are characterized by three basic ideas: enhanced mobile broadband communications, massive machine-type communications, and ultra-low-latency communications. Any of these requirements needs, to be fulfilled, the implementation of high-efficiency technologies at all levels. This includes some of the costliest mechanisms in terms of computational time and bitrate: information protection solutions. Typical techniques in this area employ complex algorithms and large protocol headers, which strongly reduces the effective baud rate and latency of future 5G networks and communications. This is especially relevant in the access network, which in 5G networks will follow a cloud-based architecture, where thousands of different devices must communicate, before aggregating all those streams to be sent to the backbone. Then, new and more efficient mechanisms are needed in the cloud radio access networks (C-RAN) for future 5G systems. Therefore, in this paper it is proposed a novel information protection scheme for C-RAN architectures based on resonant phenomena in optical fibers communicating the fronthaul and backhaul in 5G networks. Resonant structures and physical nonlinearities generate a chaotic signal which may encrypt and hide at physical level every communication stream in a very efficient manner. To evaluate the proposed mechanism, an experimental validation based on simulation techniques is also described and results discussed.
