Security enhancement of handover key management based on media access control address in 4G LTE networks

The fourth generation (4G) network is new wireless technology that offers much advancement to the wireless market. In 4G, the forward key separation plays a vital role in handover process and it can be vulnerable due to the presence of rogue base stations. Periodically updating the root key stored in base stations reduces the consequence of the attacks. But, the selection of the best possible key update interval is a vague issue as it is difficult to achieve stability between the degree of the exposed messages and the signalling load. To attack the service of websites, competitors sign up into the website multiple times and degrade the performance of the web server. Hence, this paper proposes a method that maintains history/status tables to keep a record of the media access control address in an intranet environment. The unique addresses, the media access control and internet protocol addresses are maintained in the status tables and used to identify each node distinctly. The proposed system guarantees authenticity of the host connected in the environment. Finally, the performance analysis shows that our proposed system provides better security and significant reduction in latency.
