This paper considers the problem of detecting rogue node in WiMAX networks. A rogue node is an attacker node that duplicates a legitimate node. It may lead to disturbance in service. In this paper we have proposed an efficient technique for secure data transmission to ensure the security and integrity of the data packet in the WiMAX network. We have used an ECDH algorithm for ensuring secure data transmission. Key Words: Rogue Node, Distributed Security, Elliptic Curve Diffie Hellman Algorithm(ECDH), Worldwide Interoperable for Microwave Access(WiMAX). 1. INTRODUCTION Vehicular communications have received a great deal of attention in recent years due to the demand for multimedia applications during travel and for improvements in safety. Safety applications often require fast message exchanges but do not use much bandwidth. On the other hand, multimedia services require high bandwidth for vehicular users. Hence, to provide mobile broadband services at a vehicular speed of up to 350 km/h. Worldwide interoperable for Microwave Access (WiMAX) and Long- Term Evolution (LTE) are considered the best technologies for vehicular networks. WiMAX and LTE are Fourth- Generation (4G) wireless technologies that have well-defined quality of service (QoS) and security architectures. WiMAX and LTE resemble each other in some key aspects, including operating frequency spectrum, high capacity, mobility, strong QoS mechanisms, and strong security with a similar key hierarchy from the core network to the access network. However WiMAX and LTE also differ from each other in certain aspects, as they have evolved from different origins. LTE has evolved from 3rd Generation Partnership Projects (3GPP): thus, the LTE network has to support the existing 3G users' connectivity, but there is no such constraint for WiMAX. Particularly, on the security aspect, the WiMAX authentication process uses Extensive Authentication Protocol Tunneled. Maintaining QoS requirements of a specific application has become a significant topic and priority is to maximize the QoS experienced by the user. QoS is the ability of a network to provide premier service to some fraction of total network traffic over specific underlying technologies. QoS metrics are delay, jitter (delay variation), service availability, bandwidth, throughput, packet loss rate. Metrics are used to indicate performance of particular scheme employed. QoS can be achieved by resource reservation (Integrated services), prioritization (differentiated services). 2. EASE OF USE As the increase in demand for multimedia applications and for the safety of mobile users, providing Internet that supports QoS-aware and safe multimedia services for vehicular networks is mandatory for service providers. The main cause for the MAC layer security threats in 4G vehicular networks is due to certain unprotected MAC management messages between Mobile station (MS) and Base Station (BS). When the control messages are in plain text, the attackers/intruders can easily spoof, modify, and reply those control messages for the intended receiver node. The severity of the security threats may vary based on the modification of those control messages. Similarly, the attackers may send the continuous false packets unnecessarily to the receiving node for the water torture attacks. Many research efforts have been published on MAC layer security threats in both WiMAX and LTE networks and a few of them discussed the implementation of IPSec security for WiMAX networks. In multihop WiMAX, once the user is registered with the home network the security layer may use three levels of protections for the MAC management messages, i.e., No protection, CMAC, and Encrypted by AES-CCM. As a consequence of adding the encryption support for MAC messages, some of the security threats discussed no longer exist for multihop WiMAX. However, one of the security threats such as rogue RN attack is exists that adds a rouge node/Fake node in network and creates big threaten to the 4G multihop wireless networks. Such attack causes network QoS gets degraded. So there is a need for strong security mechanisms and strict authentication methods to overcome the existing security threats in 4G multihop. But enhancing security should not degrade network QoS. Hence we proposed Elliptic Curve Diffie-Hellman (ECDH) protocol that has proven security strength and low overhead for 4G wireless networks. ECDH is competitor to RSA public key algorithm and has very good security. ECDH consumes less power and suitable for 4G wireless networks.
