WGU C839 Introduction to Cryptography - (EC-Council CES) Latest 2022

Document Content and Description Below

CrypTool ✔✔Software which allows encryption of text using historic algorithms The Enigma Machine ✔✔In World War II the Germans made use of an electro-mechanical rotor based cipher Known as T ... he Enigma Machine. Allied cipher machines used in WWII included the British TypeX and the American SIGABA. The ADFGVX Cipher ✔✔invented by Colonel Fritz Nebel in 1918. The key for this algorithm is a six-by-six square of letters, used to encode a 36-letter alphabet. The Playfair Cipher ✔✔invented in 1854 by Charles Wheatstone. The Playfair cipher uses a five-by-five table containing a keyword or key phrase. Breaking the Vigenère Cipher ✔✔In 1863, Friedrich Kasiski was the first person to publish a successful general attack on the Vigenère Cipher The Vigenère Cipher ✔✔This is perhaps the most widely known multi-alphabet substitution cipher. invented in 1553 by Giovan Battista Bellaso. Uses a series of different Caesar ciphers based on the letters of a keyword. The Cipher Disk ✔✔The cipher disk was invented by Leon Alberti in 1466. each time you turned the disk, you used a new cipher. It was literally a disk you turned to encrypt plaintext. Multi-Alphabet Substitution ✔✔Use of multiple substitution alphabets. Example:Cipher Disk, Vigenere Cipher, Enigma Machine [Show More]
