Transposition cipher

A cipher that keeps the plaintext's letters and changes their order.

A cipher that scrambles the order of the letters rather than replacing them, so the letter frequencies of the plaintext survive intact. That survival is the tell: a cipher text with the frequencies of ordinary English or Latin but no readable words is probably a transposition, or has a transposition stage, as the Zodiac's Z340 and the Kryptos K3 passage do.
