Impossible differential cryptanalysis

In cryptography, the impossible differential cryptanalysis is a form of differential cryptanalysis for block ciphers. It is impossible to have a cryptanalysis track.

The AES Candidate, DEAL. [1] The CRYPTO '98 session of the cryptographic community was followed by the impossible impossible differential ’[2] and used the technique. to break out out of the rounds of IDA [3] and 31 out of 32 rounds of the NSA-designed cipher Skipjack. [4] It was impossible to use differential cryptanalysis. [5] IDEA and Skipjack: Khufu and Khafre, E2, Serpent, MARS, Twofish, Rijndael, CRYPTON, Zodiac, Hierocrypt-3, TEA, XTEA, Mini-AES, ARIA, Camellia , and SHACAL-2.

It’s not a problem. This consists of finding "two conditions with certain conditions." [6]
