Web4 Key Recovery Attacks 4.1 Description Key recovery attacks are attempts to guess the key of the cipher in non-negligible advantage. Even if an adversary obtains some partial information of the key, such as a round key, the information becomes an im-portant clue toward full key recovery, the total break of the cipher.
