The slide attack
is a form of cryptanalysis designed to deal with the prevailing idea that even
weak ciphers can become very strong by increasing the number of rounds, which
can ward off a differential attack. The slide attack works in such a way as to
make the number of rounds in a cipher irrelevant. Rather than looking at the
data-randomizing aspects of the block cipher the slide attack works by
analyzing the key schedule and exploiting weaknesses in it to break the cipher.
The most common one is the keys repeating in a cyclic manner.
