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 G
CRYPTOGRAPHYChaotic 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. ...
secure tweakable block cipher from the Key-Alternating Feistel (KAF) structure, a dedicated Feistel structure with round functions of the form \\(F_i(k_i\\oplus x_i)\\), where \\(k_i\\) is the secret round key and \\(F_i\\) is a public random function in the i-th round. ...
It can be applied to the Feistel structure effectively. Then, we introduce CLEFIA, a representative cipher of Feistel families, and present a 11-round attack on it with differential-linear cryptanalysis. The data complexity is 2116.52 ,and we recover 96-bit keys in total. After that, the ...

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\(P_i\), 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...
