Integral Cryptanalysis

https://en.wikipedia.org/wiki/Integral_cryptanalysis

Integral cryptanalysis is a cryptanalytic attack that is particularly applicable to block ciphers based on

substitution-permutation networks. It was originally designed by Lars Knudsen as a dedicated attack

against Square, so it is commonly known as the Square attack. It was also extended to a few other

ciphers related to Square: CRYPTON, Rijndael, and SHARK. Stefan Lucks generalized the attack to

what he called a saturation attack and used it to attack Twofish, which is not at all similar to Square,

having a radically different Feistel network structure. Forms of integral cryptanalysis have since been

applied to a variety of ciphers, including Hierocrypt, IDEA, Camellia, Skipjack, MISTY1, MISTY2,

SAFER++, KHAZAD, and FOX (now called IDEA NXT).

Incorrect answers:

Chosen Plaintext Attack - is an attack model for cryptanalysis which presumes that the attacker can

obtain the ciphertexts for arbitrary plaintexts. The goal of the attack is to gain information that

reduces the security of the encryption scheme.

Linear Cryptanalysis - is a general form of cryptanalysis based on finding affine approximations to the

action of a cipher. Attacks have been developed for block ciphers and stream ciphers. Linear

cryptanalysis is one of the two most widely used attacks on block ciphers.

Differential Cryptanalysis - is a general form of cryptanalysis applicable primarily to block ciphers, but

also to stream ciphers and cryptographic hash functions. In the broadest sense, it is the study of how

differences in information input can affect the resultant difference at the output. In the case of a

block cipher, it refers to a set of techniques for tracing differences through the network of

transformation, discovering where the cipher exhibits non-random behavior, and exploiting such

properties to recover the secret key (cryptography key).
