What is a type of cipher that uses a table in which

allows someone to translate

letters into numbers?

• Pigpen Cipher

• Polybius Square

• Keyword Cipher

• Caesar cipher

What is a type of cipher that is a classic example of ancient cryptography that involves shifting each letter of the plaintext message by a certain number of letters?

• Pigpen Cipher

• Polybius Square

• Keyword Cipher

• Caesar cipher

What is a type of cipher that instead of replaces

each letter with another letter, the letters are

replaced by symbols?

• Pigpen Cipher

• Polybius Square

• Keyword Cipher

• Caesar cipher

It is a type of cipher that is a form of monoalphabetic

substitution. A keyword is used to determine the letter mapping

from plain to ciphertext. First, the repeated letters in the keyword

are removed, and then the cipher alphabet is generated.

• Pigpen Cipher

• Polybius Square

• Keyword Cipher

• Caesar cipher

Type of cipher that uses the same substitution

across the entire message. For example, if you know that the

letter A is enciphered as the letter K, this will hold true for the

entire message.

• Plygraphic Cipher

• Polyalphabetic cipher

• Keyword Cipher

• Monoalphabetic cipher

It converts the original message, called plaintext, into ciphertext

using a key to determine how it is done.
