Design of High Performance and Efficient Blowfish Algorithm by using 512 ROM Based S-Box
It is well-known that advanced encryption standard (AES) algorithm is used for protection against various classes of wireless attacks in wireless communication standard such as Wi-Fi, Wi-MAX, Zig-bee and Bluetooth. However, the AES is a complex algorithm that consumes a larger design core, time, and power source. Hence, this paper presents a development of an improved power-throughput Blowfish algorithm on Zynq-7000 field-programmable gate array (FPGA) as an alternative security algorithm. The proposed memory-based method is used to optimize the performance of Blowfish. The performance is analyzed in terms of its architecture, throughput, and power consumption. Results show that the proposed Blowfish reduces slice usage by 63% and increases throughput by 29% at low power consumption.
