A Survey of High Performance Cryptography Algorithms for WiMAX Applications Using SDR
Abstract
As wireless broadband technology has become very popular, the introduction of Worldwide Interoperability for Microwave Access (WiMAX) based on IEEE 802.16 standard has increased the demand for wireless broadband access in the fixed and the mobile devices. This development makes wireless security a very serious concern. Even though the Advanced Encryption Standard (AES) has been popularly used for protection in WiMAX applications, still WiMAX is exposed to various classes of wireless attack, such as interception, fabrication, modification, and reply attacks. The complexity of AES also produces high power consumption, long processing time, and large memory. Hence, an alternative cryptography algorithm that has a lower power consumption, faster and smaller memory, is studied to replace the existing AES. A Software Defined Radio (SDR) is proposed as a different way of proving the performance of the cryptography algorithm in real environments because it can be reprogrammed, which leads to design cost and time reductions.
