Integral Cryptanalysis of WARP based on Monomial Prediction
IACR Transactions on Symmetric Cryptology, 2022 WARP is a 128-bit block cipher published by Banik et al. at SAC 2020 as a lightweight alternative to AES. It is based on a generalized Feistel network and achieves the smallest area footprint among 128-bit block ciphers in many settings.

PENGGUNAAN INVERS MATRIKS DALAM MODIFIKASI FEISTEL CIPHER
FIBONACCI: Jurnal Pendidikan Matematika dan Matematika, 2022 Umumnya, pada algoritma kriptografi modern sistem yang digunakan adalah sistem bit. Namun, hal tersebut membuat cipherteks semakin sulit untuk dipecahkan. Saat ini, Feistel cipher merupakan salah satu algoritma kriptografi modern yang banyak digunakan karena proses pengimplementasiannya yang cukup sederhana.

Quaternion Feistel Cipher with an Infinite Key Space Based on Quaternion Julia Sets
Journal of Telecommunications and Information Technology, 2015 In this paper Quaternion Feistel Cipher (QFC) with an infinite key space based on quaternion Julia sets is proposed. The basic structure of the algorithm is based on the scheme proposed in 2012 by Sastry and Kumar.

, 2014 In this paper, we propose related-key differential distinguishers based on the complementation property of Feistel ciphers. We show that with relaxed requirements on the complementation, i.e. the property does not have to hold for all keys and the complementation does not have to be on all bits, one can obtain a variety of distinguishers.

FPE scheme based on k-splits Feistel network
Tongxin xuebao, 2012 The construction features and discipline of Feistel network-based FPE(format-preserving encryption)schemes were analyzed.Considering on the problem that 2-splits Feistel networks-based FPE cipher’s block size was in narrow range,a type-2 Feistel network ...

Elastic Block Ciphers: The Feistel Cipher Case
, 2004 We discuss the elastic versions of block ciphers whose round function processes subsets of bits from the data block differently, such as occurs in a Feistel network and in MISTY1. We focus on how specific bits are selected to be swapped after each round when forming the elastic version, using an elastic version of MISTY1 and differential cryptanalysis ...

Chosen-Key Distinguishers on 12-Round Feistel-SP and 11-Round Collision Attacks on Its Hashing Modes
IACR Transactions on Symmetric Cryptology, 2016 Since Knudsen and Rijmen proposed the known-key attacks in ASIACRYPT 2007, the open-key model becomes more and more popular. As the other component of the open-key model, chosen-key model was applied to the full attacks on AES-256 by Biryukov et al.

IEEE Access, 2021 One of the main security requirements for symmetric-key block ciphers is resistance against differential cryptanalysis. This is commonly assessed by counting the number of active substitution boxes (S-boxes) using search algorithms or mathematical ...

On Elastic Block Ciphers and Their Differential and Linear Cryptanalyses [PDF]
, 2005 Motivated by applications such as databases with nonuniform field lengths, we introduce the concept of an elastic block cipher, a new approach to variable length block ciphers which incorporates fixed sized cipher components into a new network structure.
