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...
The Generalized Feistel Structure ( $$\texttt{GFS}$$ ) is one of the most widely used frameworks in symmetric cipher design. In FES 2010, Suzaki and Minematsu strengthened the cryptanalysis security of $$\texttt{GFS}$$ by searching for shuffles with the
Our proposed model applies substitution permutation crypto concept with Feistel structure which performs substitution-permutation over five rounds to achieve higher confusion and diffusion. To retain higher security with low computation, we applied merely 64-bit block cipher and equal key-size. MATLAB ...
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 ...

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...
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. ...
