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...
Feistel Block Cipher in Cryptography - Explore the Feistel Block Cipher, its structure, and working principles in cryptography. Understand how this method enhances data security.
Chaotic systems have been proved to be useful and effective for cryptography. Through this work, a new Feistel cipher depend upon chaos systems and Feistel network structure with dynamic secret key size according to the message size have been proposed. Compared with the classical traditional ciphers...
A Lai-Massey construction uses a function and a permutation over a finite group G to define a blockcipher with block space , and its one round with input is defined as . Vaudenay [21] remarked that should be an orthomorphism (namely, is a permutation over G as well) in order to ...
In this paper, we study the security of the Key-Alternating Feistel (KAF) ciphers, a class of key alternating ciphers with the Feistel structure, where each round of the cipher is instantiated withn-bit public round permutation, namely thei-th round of the cipher maps ...

structure used by the famous block cipher DES has been active in the field of symmetric ciphers and the cryptanalysis on the structure is one of the hot topics in cryptology The appearance of AES does not diminish the appeal of the Feistel structure On the contrary it inspired many researchers...
Round Security and Super-Pseudorandomness of MISTY Type Structure(Special Section on Cryptography and Information Security) The security of all iterated block cipher heavily depends on-its structure as well as each round function. Matsui showed that MISTY type structure is faste... T Iwata,T Yoshino...
