The fifth generation (5G) networks have been deployed in some countries to offer high data rate connectivity, ultra-low latencies and increased capacities. However, security, efficiency and privacy are major issues affecting these deployments. Although a myriad of intelligent target cell section protocols has been developed, their main focus is on efficiency and quality of service improvements. As such, security and privacy are missing in these protocols. To address this gap, the third generation partnership group (3GPP) has specified authentication and key agreement (5G-AKA), and extensible authentication protocol–improved AKA (EAP-AKA’) in its Release 16(3GPP R16). However, these two protocols are susceptible to numerous attacks. To curb some of these security issues, many protocols have been presented in literature. However, these schemes are inefficient or fail to effectively meet 5G security and privacy requirements. In this paper, a protocol that simultaneously addresses efficiency, security and privacy is developed. To achieve this, an intelligent model leveraging on artificial neural network and fuzzy logic is trained and deployed for target cell prediction. During the actual handover, the user equipment, source gNB and target gNB are authenticated and a session key established. The results show that this protocol has high handover success rate and average computation and communication overheads. It offers anonymity, forward key secrecy, untraceability and is robust against numerous attack vectors.
