Uma revisão sobre os tipos de criptografia e sua aplicação na proteção de dados em trânsito

Abstract

This work aims to gather and analyze different cryptographic algorithms and evaluate them within the context of their practical application in the protection of data in transit. Through a literature review, different algorithms were compared in terms of energy efficiency, execution time and security. The results indicate that the ChaCha20 algorithm presents the best overall performance in limited devices, where there is no possible way to run hardware acceleration, while AES shows excellent performance when used with native instructions (AES-NI). Among digital signature algorithms, DSA stands out. The research highlights the importance of choosing cryptographic algorithms and how this choice should take into account the computational capacity of the device, without compromising security. The study contributes to more effective decisions in the design of secure systems in environments with and without resource constraints.
