Abstract: Security is always important in data networks, but it is particularly critical in wireless networks such as WiMAX. Authentication is the first element in wireless security that, if not well safeguarded, all following security measures will be vulnerable. Denial of Service is one of the attacks that could target a WiMAX network to make its operation inefficient. This paper is an investigation into a) the weakness and threats on WiMAX security algorithms and b) the best method that could prevent DoS attacks prio… Show more

Authentication is one of the most important security processes in Worldwide Interoperability for Microwave Access (WiMAX) networks. This process allows the receiver (whether base station or subscriber station) of a packet to be confident of the identity of the sender and the integrity of the message. Most attacks will attempt to violate the authentication process. If such attacks become successful, an attacker will gain an illegitimate access to network resources, thus increasing the probability of future malicious attacks. A number of algorithms and methods have been proposed to improve the security level of authentication in WiMAX networks. However, the evaluations of these algorithms and methods have always been based on a particular aspect, such as reducing overhead, protecting unauthenticated management messages, preventing WiMAX from external attacks, and protection during the handover process. Motivated by these variations, we review the state of art of WiMAX authentication mechanisms, namely, PKMv1, PKMv2, and the recent authentication protocols. We discuss their mechanisms, strengths, weaknesses, and potential countermeasures against each other. Our discussion is based on four categories, namely, enhancements, differences, advantages, and limitations. Copyright © 2016 John Wiley & Sons, Ltd.

In the present era of high speed communication, wireless technology plays a predominant role in data transmission. In the timeline of wireless domain, Wi-Fi, Bluetooth, ZigBee are some of the standards used in today's wireless medium. In addition, WiMax is introduced by IEEE as IEEE 802.16 standard for long distance communication, and mobile WiMax as 802.16e. WiMax is an acronym of worldwide interoperability for microwave access. It helps to provide wireless transmission with high quality of service in a secured environment. Privacy across the network and access control is the predominant goal in the wireless protocol. In the wireless environment one of the most widely used security algorithms in MAC layer is Advanced Encryption Standard (AES). Especially Medium Access Control (MAC) sub layer should be evaluated in the security architecture. AES is used in the MAC layer that consumes more power and involves high cost. So, in this paper an optimized architecture of AES 128 bit counter mode security algorithm for MAC layer of 802.16e standard is proposed. The SBOX and MixColumn transformation are modified in the architecture of AES to achieve optimized power and delay. The design has been implemented in Xilinx virtex5 device and power has been analyzed using XPower analyzer. It is compared with two standard existing architectures. The simulation results revealed a power reduction of 41% compared to existing one.
