What is Simplified DES Encryption Overview about?
This document describes a simplified version of the Data Encryption Standard (DES) algorithm called S-DES. It provides details on the key generation process and the main functions used in the encryption algorithm, including an initial permutation, complex encryption function fk, switch function, and final permutation. It also describes how to implement the algorithm in MATLAB using the defined functions and how to conduct a brute force attack to decrypt a ciphertext by trying all possible keys.
