D334 Introduction to Cryptography
WGU Western Governors University
Read All Instructions Carefully and Answer All the
Questions Correctly Good Luck: -
1. Pigpen Cipher: Mono- alphabetic substitution cipher that
makes use of mapping plaintext characters to graphical
characters rather than to alphabetic ones. i.e. A=(pick a
symbol), vs A=(pick a letter). Disadvantage: once the
mapping is known, it is difficult to keep the message secret.
2. Rail Code Cipher: Employs a method to scramble text by
writing it in a sequence across a number of rails.
3. BIFID Cipher: Makes use of a grid and which maps the
letters into numeric values.

4. Playfair Cipher: 5 × 5 matrix containing the alphabet less
the letter J. Cipher/deci- pher process consists of a set of
rules outlining use of column and row combinations.
5. Morse Code: Encoding method, rather than a cipher, that
works by translating characters into sequences of dots (.) and
dashes (-)
6. Ceasar Cipher: Mono-alphabetic substitution cipher known
as "shift" cipher. In- volves plaintext being replaced by a
letter some fixed number of positions down the alphabet.
7. Vigenere Cipher: Polyalphabetic cipher that involves using
a different mapping, based on a keyword, for each character
of the cipher. An advantage of this type of cipher is that the
same plaintext character is likely to be coded to different
mappings, depending on the position of the keyword, making
guessing more difficult.
8. one-time pad (OTP): Cipher code mapping that is used only
once. Advantage is it is essentially unbreakable,
disadvantage is it takes lots of work as you'd have to
generate the pad to be used, each time.
9. Four-Square Cipher: Uses four 5 × 5 matrices arranged in
a square, are where each matrix contains 25 letters for
encoding and decoding operations.
10. Enigma Machine: Used a polyalphabetic substitution
cipher, which did not repeat within a reasonable time period,
along with a secret key. For the cracking
of the Enigma cipher, the challenge was thus to determine both
the algorithm used and the key. Enigma's main weakness,
though, was that none of the plain text letters could be
ciphered as itself.
11. AND: Both the first and second numbers must be 1 for the
answer to be 1. Anything else = 0
