A Comparative Study of Twofish, Blowfish, and Advanced Encryption Standard for Secured Data Transmission

Abstract

Now-a-days, network security is becoming an increasingly significant and demanding research area of interest. Threats and attacks on information and Internet security are getting increasingly difficult to detect. As a result, encryption has emerged as a solution and now plays a critical role in information security systems. Many techniques are required to safeguard shared data. In this work, the encryption, decryption times, and throughput (speed) of the three most commonly used block cipher algorithms: Twofish, Blowfish, and AES were investigated using different file types. Comparison of symmetric encryption techniques of experiments on these types of algorithms uses a lot of computer resources including CPU time, memory, and battery power. Previous research has yielded diverse results in terms of time complexity, speed, space complexity, power consumption, and security. However, this research evaluated the effectiveness of each algorithm based on the following parameters: process time and speed. An application was developed for data simulation to test different file formats and for the encryption process and speed using Python 3.10.
