Design And Performance Analysis of High-Speed Blowfish Cryptosystem

Abstract

In the era of information on cloud, the information security plays a critical role. There are so many security schemes available. All the available security schemes developed by many folds encoding of original data. Because of these complex many fold security steps, all these algorithms taking long time to compute the cipher text. Blow fish algorithm is a popular encryption scheme. This algorithm involves many complex stages. To compute these complex stages, software program may take long time. There by many other factors like power consumption and throughput also effects. To avoid these difficulties, a high-speed crypto algorithm based on Blowfish security scheme is developed. Hardware implementation of the proposed algorithm may be useful in high-speed communication systems. Entire system is described using Verilog HDL and is implemented using Spartan 3E FPGA.
