Identification Of Better Encryption Algorithm in Securing Data

Abstract

Over the last few years, the usage of the internet has grown considerably in many fields. Data security has become the biggest challenge due to the wide spread usage of the internet. The data that are transferred through the internet or any public network can be easily accessed by unauthorized hackers. One of the best ways to avoid this problem is data encryption. Securing data from unauthorized access is known as encryption which uses many algorithms.  Each algorithm has its own strength and weakness. These encryption algorithms are utilized efficiently when it is secure and fast in performance. This work offers a comparative analysis of some widely accepted encryption algorithms such as Advance Encryption Standard (AES), Data Encryption Standard (DES), Rivest-Shamir-Adleman (RSA), Blowfish, and Caesar Cipher in terms of data protection, data reliability, scalability, and integrity. Out of these the best one is selected for testing its sustainability. The Brute Force attack and the DOS attack are chosen to test the encryption algorithm.
