A Construction of Security Enhanced and Efficient Handover AKA Protocol in 5G Communication Network

Abstract

In order to accommodate the increasing security demands of Internet of Things (IoT)-based applications, the Third Generation Partnership Project (3GPP) has announced the Fifth Generation (5G) communication technology with the security amendments such as flexible placement of User Plane (UP) functions and network slicing which were not achieved in Fourth Generation (4G) Long Term Evolution (LTE) network. In this paper, we identified the security weaknesses in existing 5G handover protocol such as false base-station attack, lack of Key forward/backward secrecy (KFS/KBS), Denial of Service (DoS) attack, and high network complexity. In order to modify the above issues, we construct a security enhanced and efficient handover authentication and key agreement protocol in 5th genration communication network. The formal analysis of proposed protocol is carried out by AVISPA tool to prove its correctness. Finally, the performance evaluation of the protocol is shown with existing 5G handover protocol. The analysis shows that the proposed protocol has improved results in terms of communication and computation overhead.
