Network coding (NC)-enabled mobile small cells are observed as a promising technology for fifth-generation (5G) networks that can cover the urban landscape by being set up ondemand at any place and at any time on any device. Nevertheless, despite the significant benefits that this technology brings to the 5G of mobile networks, major security issues arise due to the fact that NC-enabled mobile small cells are susceptible to pollution attacks; a severe security threat exploiting the inherent vulnerabilities of NC. Therefore, intrusion detection and prevention mechanisms to detect and mitigate pollution attacks are of utmost importance so that NC-enabled mobile small cells can reach their full potential. Thus, in this article, we propose for the first time, to the best of our knowledge, a novel intrusion detection and prevention scheme (IDPS) for NC-enabled mobile small cells. The proposed scheme is based on a null space-based homomorphic message authentication code (MAC) scheme that allows detection of pollution attacks and takes proper risk mitigation actions when an intrusive incident is detected. The proposed scheme has been implemented in Kodo and its performance has been evaluated in terms of computational overhead.

“…5G communications target to achieve big data bandwidth, infinite capability of networking and extensive signal coverage to support a plethora of high-quality personalised services to subscribers, while at the same time the capital and operating expenditures (i.e., CAPEX and OPEX) of mobile operators are being reduced. Towards this direction, 5G communications systems will integrate a wide spectrum of enabling technologies [1][2][3][4][5].…”

The recent explosive growth of mobile data traffic, the continuously growing demand for higher data rates, and the steadily increasing pressure for higher mobility have led to the fifth-generation mobile networks. To this end, network-coding (NC)-enabled mobile small cells are considered as a promising 5G technology to cover the urban landscape by being set up on-demand at any place, and at any time on any device. In particular, this emerging paradigm has the potential to provide significant benefits to mobile networks as it can decrease packet transmission in wireless multicast, provide network capacity improvement, and achieve robustness to packet losses with low energy consumption. However, despite these significant advantages, NC-enabled mobile small cells are vulnerable to various types of attacks due to the inherent vulnerabilities of NC. Therefore, in this paper, we provide a categorization of potential security attacks in NC-enabled mobile small cells. Particularly, our focus is on the identification and categorization of the main potential security attacks on a scenario architecture of the ongoing EU funded H2020-MSCA project "SECRET" being focused on secure network coding-enabled mobile small cells.

“…To address these challenges, new technologies are emerging to create the next generation 5G network [5,6,7,8,9]. These new technologies will deliver higher network capacity, allow the support of more users, lower the cost per bit, enhance energy efficiency, and provide the adaptability to introduce future services and devices.…”

The continuous growth in wireless devices connected to the Internet and the increasing demand for higher data rates put ever increasing pressure on the 4G cellular network. The EU funded H2020-MSCA project "SECRET" investigates a scenario architecture to cover the urban landscape for the upcoming 5G cellular network. The studied scenario architecture combines multi-hop device-to-device (D2D) communication with network coding-enabled mobile small cells. In this scenario architecture, mobile nodes benefit from high transmission speeds, low latency and increased energy efficiency, while the cellular network benefits from a reduced workload of its base stations. However, this scenario architecture faces various security and privacy challenges. These challenges can be addressed using cryptographic techniques and protocols, assuming that a key management scheme is able to provide mobile nodes with secret keys in a secure manner. Unfortunately, existing key management schemes are unable to cover all security and privacy challenges of the studied scenario architecture. Certificateless key management schemes seem promising, although many proposed schemes of this category of key management schemes require a secure channel or lack key update and key revocation procedures. We therefore suggest further research in key management schemes which include secret key sharing among mobile nodes, key revocation, key update and mobile node authentication to fit with our scenario architecture.
