Abstract
Computer data communication is the order of the day with Information Communication Technology (ICT) playing major role in everyone’s life, communicating with smart phones, tabs, laptops and desktops using internet. Security of the data transferred over the computer networks is most important as for as an organization is concerned. Hackers attempt hard to crack the software key and indulge in cyber crimes. In this paper, the main concern is not only to provide security to the data transferred at the software level but it provides the security at hardware level by the modified Blowfish Encryption and Decryption Algorithms. It results minimum delay, high speed, high throughput] and effective memory utilization compared to Blowfish (BF) and Triple Data Encryption Standard (TDES) algorithms. The implementation of Blowfish with modulo adder and Wave Dynamic Differential Logic (WDDL) is to provide security against Differential power analysis (DPA). In the proposed four implementations, BF with constant delay n-bit adder (BFCDNBA) yielded minimum delay, maximum frequency, high memory utilization and high throughput compared to BF with modulo adder and WDDL logic (BFMAWDDL), BF with modulo adder (BFMA) and TDES algorithms. The VLSI implementation of Blowfish and TDES algorithms is done using Verilog HDL.
