ühe biti pööramine krüptogrammis, mis on loodud jadašifriga; pöörab vastava biti avatekstis ja on eriti ohtlik, kui avateksti vorming on teada; ei toimi MAC-koodi kasutamisel
= an attack in which the attacker can change the ciphertext in such a way as to result in a predictable change of the plaintext, although the attacker is not able to learn the plaintext itself
