Next generation wireless networks involve diverse wireless access technologies to support multimedia services to the roaming users with different Quality of Service constraints at anytime and anywhere. The increased number of users and service providers in the integrated network architecture requires authentication mechanism between communication entities to ensure secured handover. The existing security standards of each network are not able to provide most favorable security requirements of the heterogeneous networks because of independent and incompatibility of various wireless networks. Therefore, Trust and Privacy based Multi-attribute Vertical Handoff (TPMVHO) decision algorithm along with Hybrid Genetic Cuckoo Search algorithm to optimize the attributes weight is proposed to select an optimal network for secure handoff mechanism. Simulation results show the reduction in handoff rate, blocking rate and enhanced throughput against Improved Particle swarm optimization based Multi-attribute Vertical Handoff (IPMVHO).

The emergence of new services in 5G has necessitated a paradigm shift in the core network, as compared to 4G. New disruptive technological concepts such as softwarized and virtualized network functions, and multi‐access edge computing have been used in the core network. Thus, network function virtualization (NFV), software‐defined networking (SDN) and mobile edge computing have brought dynamicity and elasticity into the core network. Albeit the benefits, these technologies also bring their own limitations into the core network. Security challenges, for instance, constitute one such challenge dimension that need proper investigation into the loopholes existing in these technologies, and thus seek solution to those challenges. In this article, we discuss the security of 5G core network. The potential security challenges and possible solutions for the core network as a whole, and its key functions and technologies are discussed in this article.
