ESTUDIO COMPARATIVO DE LA EFICIENCIA DE LOS ALGORITMOS CRIPTOGRÁFICOS AES Y RSA: CASO DE ESTUDIO DE UNA INSTITUCIÓN EN LA CIUDAD DE GUAYAQUIL

Abstract

The present work makes a research and analysis on the most commonly used cryptographic algorithms, AES and RSA, in order to obtain information about its operation, characteristics, structure, components and first of all, to know its efficiency and robustness to find the most suitable to ensure an adequate implementation and solution to ensure a reasonable level of information security, which at the moment is so necessary for the development of organizations and at the same time it is so vulnerable to any computer attacker that seeks to steal, alter or modify it. In order to achieve the objective set out in this research, it was used an encryption simulation, made in five text files of different sizes, using the selected algorithms, through a free software called JCryptool, which the following parameters were used to evaluate the performance of the same ones: calculation time, use Memory, output bytes. In this way, the results show that the values of the calculation time, the memory usage and the output bytes used by the RSA algorithm are greater than the parameters evaluated with the AES algorithm, in all the files used in the simulation.
