WebThe basic difference between DES and AES is that the block in DES is divided into two halves before further processing whereas, in AES entire block is processed to obtain ciphertext. The DES algorithm works on … WebJan 3, 2024 · DES is a complex algorithm that works by dividing an input text into smaller 64-bit blocks. Each block then goes through an initial permutation, and the result of the initial permutation is further divided into two parts called LPT and RPT. These two parts then go through the Feistel function for 16 rounds.

WebS-DES depends on the use of a 10-bit key shared between sender and receiver. From this key, two 8-bit subkeys are produced for use in particular stages of the encryption and decryption algorithm. First, permute the key in the following fashion. Let the 10-bit key be designated as (k1, K2, k3, k4, k5, k6, k7, k8, k9, k10). WebAug 18, 2024 · Data encryption standard (DES) is a symmetric key block cipher algorithm. The algorithm is based on Feistel network. The algorithm uses a 56-bit key to encrypt data in 64-bit blocks. There are mainly two categories of concerns about the strength of Data encryption standard.
