Privacy-Aware Secure Region-Based Handover for Small Cell Networks in 5G-Enabled Mobile Communication

The 5G mobile communication network provides seamless between users and service providers promises to achieve several stringent requirements, such as mobility massive connectivity. Although can offer numerous benefits, security privacy issues still need be addressed. For example, the inclusion of small cell networks (SCN) into brings closer connected users, providing a better quality services (QoS), resulting in significant increase number Handover procedures (HO), which will affect security, latency efficiency network. It is then crucial design scheme that supports handovers through secure authentication process. With this aim, article, we propose region-based handover connectivity for SCNs 5G. Our proposed based on asymmetric-key-based authenticated key exchange protocols preserve user while mechanism effective membership revocation management. In context, introduce three privacy-preserving protocols, i.e., an initial protocol, intra-region protocol inter-region dealing with scenarios. To best our knowledge, first paper consider both scenarios management support. Detailed performance analysis presented show it resilient against many threats, cost-effective efficient solution 5G-enabled communication.
