Algoritmos DES e AES: Comparação dos processos de geração de chaves e cifração

Resumo

Cryptographic algorithms are the basis of information security, whether in symmetric or asymmetric systems. The objective of this article is to compare the symmetric algorithms DES and its replacement AES, regarding the security and speed of the encryption and key generation processes. The aim of this work is to indicate which cryptographic algorithm is the safest and fastest based on the indicated criteria. The result obtained is that some points led to AES being more secure, particularly because its cryptographic process has a very complex architecture and uses 128, 192 and 256-bit keys, which are considered strong today.
