Integral cryptanalysis represents a particular cryptanalytic attack that is applicable to the block ciphers that are built based substitution-permutation networks. The attack was designed by Lars Knudsen as a dedicated attack against Square [1], leading it to be known as the Square attack.

The substitution-permutation networks represent one of the most important vulnerable points of block ciphers. Once the networks can be found (let’s say intuitively) then the attack on the block ...
