- E x e r c i s e • 1 : Apply frequency test to verify the randomness of the output of the following text: 1. The following plaintext: In cryptography, a transposition cipher (also known as a permutation cipher) is a method of encryption which scrambles the positions of characters (transposition) without changing the characters themselves. Transposition ciphers reorder units of plaintext (typically characters or groups of characters) according to a regular system to produce a ciphertext which is a permutation of the plaintext. They differ from substitution ciphers, which do not change the position of units of plaintext but instead change the units themselves. Despite the difference between transposition and substitution operations, they are often combined, as in historical ciphers like the ADFGVX cipher or complex high-quality encryption methods like the modern Advanced Encryption Standard (AES). laintexts can be rearranged into a ciphertext using a key, scrambling the order of…Write true or false for each.Let M be the plaintext message M = MALAYSIA and the private key, K || ISSOGOOD a) Represent your plaintext binary number as a form of a block, using the DES encryption technique (2 equal blocks). b) Using the initial permutation (table is provided below), please provide your plaintext output.
