Abstract
The demand for wireless broadband access through mobile devices has increased impressively causing wireless security to be a very serious concern. Most of wireless communication standards implement an advanced encryption standard (AES) algorithm for protection against various classes of wireless attack such as interception, fabrication, modification and reply attacks. However, the AES is a complex algorithm that consumes more memory, time, and battery power. In this paper, the performance of the proposed AES and Blowfish algorithms with improved power-throughput are analysed and compared using Virtex6 field programmable gate array (FPGA) in terms of their architecture, throughput and power consumption. The results show that the proposed Blowfish has reduced slices usage and power consumption by 1 and 6 % respectively, and increased the throughput by 36 %.
