A unique message encryption technique based on enhanced blowfish algorithm

Abstract

Online transaction especially sending of messages has become easier and simpler to be manipulated. Nonetheless, security is the important aspect to secure its content and raise difficulty to unauthorized attempt. This study aims to secure both plaintext and file message content through encryption technique which is based on enhanced Blowfish algorithm. An enhanced Blowfish algorithm is developed to improve its performance by reducing the number of rounds and by increasing the block length with fixed length during encryption and decryption with added transformation method on selected rounds. The study used Visual Studio application running at x64 operating system.
