- AThe Playfair Cipher
- BCaesar
- CScytale
- DThe Vigenère cipher

- AThe Playfair Cipher
- BCaesar
- CScytale
- DThe Vigenère cipher
- EAffine cipher
97Name the historical cipher: "invented in 1553 by Giovan Battista Bellaso, but is named for the man who developed a stronger version of the cipher. It is a method of encrypting by using a series of interwoven Caesar ciphers based on the letters of a keyword. It is considered a polyalphabetic cipher system. Friedrich Kasiski published the first successful attack against it in 1863."
- AThe Playfair Cipher
- BCaesar
- CScytale
- DThe Vigenère cipher
- EAffine cipher
98Name the historical cipher: invented by Charles Wheatstone in 1854. Uses a five-by-five table containing a keyword or key phrase. To generate the key table, one would first fill in the spaces in the table with the letters of the keyword (dropping any duplicate letters), then fill in the remaining spaces with the rest of the letters of the alphabet in order. The technique encrypts pairs of letters (digraphs), instead of single letters as in the simple substitution cipher. This is significantly harder to break since the frequency analysis used for simple substitution ciphers does not work with it.
- AThe Playfair Cipher
- BCaesar
- CScytale
- DThe Vigenère cipher
- EAffine cipher
99Name the historical cipher: It is a type of monoalphabetic substitution cipher, wherein each letter in an alphabet is mapped to its numeric equivalent, encrypted using a simple mathematical function, and converted back to a letter.
