Quizplus · Accepted Answer

In transposition ciphers, the positions of the letters in the plaintext are shifted according to a regular system, so that the ciphertext constitutes a permutation of the plaintext. This is different from substitution ciphers, where each letter or group of letters is replaced by another letter or group of letters without altering the sequence of the letters in the message.
