In this paper previous algorithm based on DNA cryptography is enhanced in terms of its security parameter by incurring feistel inspired structure in it. This adds some sort of confusion and diffusion, which makes it complex enough that it restricts the adversary to perform any kind of brute ...
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.
Feistel construction is a central object in cryptography. An r round Feistel construction is the r-composition of the so-called Feistel permutations, where consists of executing a (probably random) function and a swap operation. A Feistel construction is balanced, if . Assume that are random func...
一类扩展广义Feistel结构抵抗差分和线性密码分析能力评估
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 ...
Feistel structure 设函数的输入含有n个比特 0 L和 0 R各含n 2个比特 首先给出攻击的明文结构 在后面所述的高阶 差分攻击中 中间起始状态左半部分的全部比特都是活跃比特 也就是说 这些比特在代数次数的估计中 都将被视为变量 所以攻击中会遍历它们的取值 右半部分的一部分比特活跃 剩余比特的值固定 通常...
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...

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...
