DEVELOPMENT OF AN IMPROVED BLOWFISH ALGORITHM USING MEMORY BASED METHOD

Abstract

It is well-known that Advanced Encryption Standard (AES) algorithm is employed for cover against various categories of wireless attacks in wireless communication standard like Wi-Fi, Wi-MAX, Zig-bee and Bluetooth. However, the AES is a complex algorithm that consumes a bigger design core, time, and power supply. Hence, this paper presents a development of an improved power-throughput Blowfish algorithm on Field-Programmable Gate Array (FPGA) as an alternate security algorithm. within the extension for this work we proposed memory-based method is used to optimize the performance of Blowfish by replace 1024 rom with the 512 KB of rom because of that The performance is analyzed in terms of its design, throughput, and power consumption.
