Comparative Analysis of Encryption Algorithms using Simulation Technique

Abstract

The unprotected electronic document may be subjected to a data breach in which private or sensitive information is stolen, taken, altered, copied, communicated, viewed, or used without authorization. This study evaluates the four most common encryption algorithms like Data Encryption Standard (DES) Algorithms, Rivest Cipher2 Algorithm (RC2), Triple Data Encryption Standard (3DES), and Advanced Encryption Standard (AES). This aims to compare four (4) encryption algorithms using simulation Technique to know the algorithm that encrypts and decrypts data faster in VB.Net of different data block sizes to determine their performance (speed). The simulation comparison technique using the VB.Net programming language was adopted as the method for the study. A graphical user interface (GUI) was developed, and four algorithms were programmed to simulate and analyse their performance based on speed. As a result, the four Encryption Algorithms were analysed and found that the Advanced Encryption Standard algorithm (AES) performs much faster in VB.Net.
