Abstract

Mobile Multihop Relay (MMR) network is one of the emerging technologies, especially LTE-Advanced, WiMAX and the Smart grid communications. Ensuring security is one of the most imperative and challenging issues in MMR networks. Privacy Key Management (PKM) protocol is proposed to ensure the security measures in MMR networks. However, the protocol still faces several security threats, specifically Denial of Service (DoS), replay attacks, Man in the Middle (MitM) attacks and the interleaving attacks, which is termed as Medium Access Control (MAC) layer attacks. This paper proposed a modified version PKM protocol for both unilateral and mutual authentication, which is termed as Self-organized Efficient Authentication and Key Management Scheme (SEAKS) authentication protocol. This protocol ensures secure end-to-end data transmission using distributed hop-by-hop authentication and localized key management schemes with a very simple and efficient way. The performance evaluation of the proposed schemes in terms of packet delivery ratio, packet overhead, processing time and the effect of increasing number of rogue relay stations is carried out and compared with the official draft of MMR WiMAX and the SEN XU. The result showed that our proposed scheme out-performed the base line protocols. Keywords: Denial of Service, Hop-by-Hop Authentication, IEEE 802.16, MMR WiMAX Network, Security Issues

Summary

Introduction

Introduction of relays to support multi-hopping in MMR WiMAX networks increases the wireless converges and provides features such as lower backhaul deployment cost, easy setup and high-throughput[1]. In the security sublayer of WiMAX, two sets of protocols are provided: an encapsulation protocol for encrypting data across Broadband Wireless Access (BWA), and a PKM protocol for secure distribution of keying materials from the Base Station (BS) to the Subscriber Station (SS) and for enforcing conditional access by the BS. The PKM protocols work in two different versions, i.e. PKMv1 and PKMv2. PKMv1 allows only unilateral authentications, and PKMv2 allows mutual authentications. It supports periodic re-authentication/re-authorization and key refresh[3].
