The ____ cipher rearranges the values within a block to create the ciphertext.
A) transposition
B) polyalphabetic substitution
C) Vernam
D) monoalphabetic substitution

Question

Quizplus · Accepted Answer

A transposition cipher is a type of encryption where the positions of the plain text letters are shifted by a certain amount. Rather than substituting letters for other letters, like in monoalphabetic and polyalphabetic substitution ciphers, a transposition cipher simply rearranges the order of the letters to create the ciphertext. The Vernam cipher, also known as a one-time pad, involves applying a bitwise XOR operation to the plaintext and a random key of the same length to generate the ciphertext.
