Question

Question 7 12.5 pts Recall that book ciphers do not necessarily require a full book to decode, but instead any written text, such as the Declaration of Independence. For the example discussed in class (the second Beale cipher), we created the key by numbering words and taking the first letter. But we can also number characters themselves instead, making sure to skip spaces. The following is a message encrypted with a book cipher, using the text of this question as a key. What is the hidden message? (Write your answer with or without spaces between the words, in lower case.) 37 25 41 46 13 41 24 56 26 18 28 9 27 2175 2 34 Question 8 12.5 pts With respect to the type of mapping between the plaintext alphabet and the ciphertext alphabet, which of the following types of cipher is a book cipher conceptually most similar to? Caesar Shift Cipher Monoalphabetic substitution cipher Monoalphabetic substitution cipher with a keyword Monoalphabetic substitution cipher with homophones Vigenere cipher

Answer 1
