ANÁLISIS Y COMPARACIÓN DE LOS ALGORITMOS DE CIFRADOS SIMÉTRICO EN PLATAFORMAS WINDIWS

Abstract

The main purpose guiding the design of any encryption algorithm should be security against unauthorized attacks. However, for all practical applications, performance and speed are also important concerns. These are the two main features that differentiate one encryption algorithm from another. This document provides the performance comparison between two of the most commonly used encryption algorithms: AES (Rijndael) and Blowfish. The comparison has been made by running encryption to process various file sizes and evaluating the encryption / decryption speed of the algorithm in different versions of the Windows platform for workstations. The simulation was done using a file encryption tool that allows us to choose between AES and Blowfish algorithms in virtual machines operating systems Windows 7, Windows 8.1 and Windows 10, thus determining the influence of the operating system on the speed of each of the algorithms chosen, it has been concluded that Windows 10 significantly accelerates the encryption and decryption of files with either AES or Blowfish.
