The One Time Pad (OTP) has been a staple of the cryptography community ever since it was invented; publications such as Academic Accelerator even claim that the method \u201cin cryptography is an encryption technique that cannot be broken\u201d[5]. As learned in class, the use of OTP requires a sequence of key bits (or Pad) the same length as the plaintext message to be generated randomly, then xor\u2019d with the plaintext, producing a ciphertext that achieves perfect secrecy. However, when a key is re-used to encrypt multiple plaintexts, the security of the system is compromised [1]. A cryptanalysis technique known as Crib-Dragging [2] can be used to uncover the contents of the plaintexts with the re-used key, as well as reconstruct the key\/pad that was used. The technique works by the adversary guessing<\/em> what the plaintext encrypted was to obtain a partial pad, then testing the guess by decrypting the other ciphertexts under the partial pad to see if sensible results are produced. If the adversary knows the content type that was decrypted this can become increasingly easy as seen in class with common english words being used to decrypt the three ciphertexts.<\/p>\n\n\n\n

The appeal of the game-like nature of crib-dragging was immediately apparent to our group who enjoyed its puzzle-game nature as we navigated the terminal based game from classroom Worksheet 02. Our proposed Unessay is to improve on that (ever so slightly tedious) game, with a new game called Crib-Draggle<\/em>. The vision is to create something similar to New York Times\u2019 Wordle<\/em> [7].<\/p>\n\n\n\n
