Cryptography series: feistel cipher Introduction Feistel cipher is also called Luby-Rackoff block cipher, which is used to construct a symmetric structure of block encryption algorithm. It was invented by the German cryptographer Horst Feistel while working at IBM. Feistel cipher is also called Feiste...

In order to find such a specific impossible trail, Biham et al. proposed the method of miss-in-the-middle (Biham et al. 1999b), which aims at searching two differences which propagate through the cipher forward and backward respectively, and make contradictions in the middle. The idea of...
An important step for realizing a chaotic cryptography, that is, mapping real numbers in continuum into integers in a finite set is researched. On the base of conventional Feistel-structure, a 128 bits key cipher block algorithm based on chaos is proposed. Confusion and diffusion are necessary ...
You take a block of an even number of bits and split it into two sub-blocks, the left halfLand the right halfR. Thenth round of a Feistel cipher creates new left and right blocks from the left and right blocks of the previous round by ...

In a seminal work, Luby and Rackoff [12] proved that a three-round Feistel scheme can securely perform pseudo-random permutation. However, Kuwakado and Morii [13] introduced a quantum distinguisher attack on 3-round Feistel ciphers that could distinguish between the cipher and a random ...
