“…They defined 5G availability as a function of radio access network, control plane and support system and that any attack on these systems impacts availability; while Authentication is a means to Non-Repudiation for device-to-device communication on the network. Integrity is applicable to user plane integrity protection and they reported that the radio access of the 5G works closely with cloud services whose security threats centres around Denial of service (DoS), this affects the operation of the network slice, jamming attack that impact the resources of the 5G radio access in [17], 5G security architecture was divided into Application layer security (such as smart grid, smart city, web application), service layer security (such as IoT, IoE), virtual layer security (virtual network, virtual compute), physical layer security (core network security), SDN security (data and control), Slicing security, Management and orchestration. They reported the architecture and challenges of 5G technology.…”

“…This makes them inherit the 5G security threats that are associated with these 5G technologies. New threats and security loop holes have been uncovered in networks including 5G, this makes assessment and evaluation of the 5G security to be checked from time to time to ascertain its capability to ward off emerging threats [17]. The work by [17] surveyed possible known and unknown threats that could affect 5G technology and suggested that more resilience is needed for security measures that will be appropriate for implementation in all aspects of the 5G technology.…”

The roll out of the deployment of the 5G technology has been ongoing globally. The deployment of the technologies associated with 5G has seen mixed reaction as regards its prospects to improve communication services in all spares of life amid its security concerns. The security concerns of 5G network lies in its architecture and other technologies that optimize the performance of its architecture. There are many fractions of 5G security architecture in the literature, a holistic security architectural structure will go a long way in tackling the security challenges. In this paper, the review of the security challenges of the 5G technology based on its architecture is presented along with their proposed solutions. This review was carried out with some keywords relating to 5G securities and architecture; this was used to retrieve appropriate literature for fitness of purpose. The 5G security architectures are majorly centered around the seven network security layers; thereby making each of the layers a source of security concern on the 5G network. Many of the 5G security challenges are related to authentication and authorization such as denial-of-service attacks, man in the middle attack and eavesdropping. Different methods both hardware (Unmanned Aerial Vehicles, field programmable logic arrays) and software (Artificial intelligence, Machine learning, Blockchain, Statistical Process Control) has been proposed for mitigating the threats. Other technologies applicable to 5G security concerns includes: Multi-radio access technology, smart-grid network and light fidelity. The implementation of these solutions should be reviewed on a timely basis because of the dynamic nature of threats which will greatly reduce the occurrence of security attacks on the 5G network.

Nowadays, by integrating the cloud radio access network (C-RAN) with the mobile edge cloud computing (MEC) technology, mobile service provider (MSP) can efficiently handle the increasing mobile traffic and enhance the capabilities of mobile devices. But the power consumption has become skyrocketing for MSP and it gravely affects the profit of MSP. Previous work often studied the power consumption in C-RAN and MEC separately while less work had considered the integration of C-RAN with MEC. In this paper, we present an unifying framework for the power-performance tradeoff of MSP by jointly scheduling network resources in C-RAN and computation resources in MEC to maximize the profit of MSP. To achieve this objective, we formulate the resource scheduling issue as a stochastic problem and design a new optimization framework by using an extended Lyapunov technique. Specially, because the standard Lyapunov technique critically assumes that job requests have fixed lengths and can be finished within each decision making interval, it is not suitable for the dynamic situation where the mobile job requests have variable lengths. To solve this problem, we extend the standard Lyapunov technique and design the VariedLen algorithm to make online decisions in consecutive time for job requests with variable lengths. Our proposed algorithm can reach time average profit that is close to the optimum with a diminishing gap (1/V) for the MSP while still maintaining strong system stability and low congestion. With extensive simulations based on a real world trace, we demonstrate the efficacy and optimality of our proposed algorithm.

“…SDN/NFV technologies are introduced into new 5G network architectures, thereby decoupling the control and data planes of the equipment [28,29], which creates favorable conditions for building new device trust relationships based on general IT hardware platforms from multiple manufacturers. The concept of being more open, and cloudy/pooling architecture designs also promote many security challenges [15,27,30]. In addition, security boundaries and protection modes in the traditional closed management mode are undergoing profound changes, and the openness of a business, the user's customization, and the ability to visualize the application of resources bring unprecedented challenges to providing security and credibility to cloud platforms [31].…”

The 5th-generation mobile communication system (5G) has higher security requirements than previous systems. Accordingly, international standard organizations, operators, and equipment manufacturers are focusing extensively on 5G security technology. This paper analyzes the security requirements of 5G business applications, network architecture, the air interface, and user privacy. The development trends of 5G security architecture are summarized, with a focus on endogenous defense architecture, which represents a new trend in 5G security development. Several incremental 5G security technologies are reviewed, including physical layer security, lightweight encryption, network slice security, user privacy protection, and block chain technology applied to 5G.
