An Image Encryption Method Based on the Feistel Network and Dynamic DNA Encoding
IEEE Photonics Journal, 2018 Based on the Feistel network and dynamic deoxyribonucleic acid (DNA) encoding technology, an image encryption method is proposed using the “permutation–diffusion–scrambling” structure.

Extended Generalized Feistel Networks Using Matrix Representation [PDF]
, 2014 While Generalized Feistel Networks have been widely studied in the literature as a building block of a block cipher, we propose in this paper a unified vision to easily represent them through a matrix representation. We then propose a new class of such schemes called Extended Generalized Feistel Networks well suited for cryptographic applications.

Yoyo trick on type‐II generalised Feistel networks [PDF]
IET Information Security, 2021 This work presents a structural attack against the type‐II generalised Feistel network (GFN) with secret internal functions. First, equivalent structures of the 7‐round type‐II GFN are provided, which helps reduce the first guess of the secret round ...

Distinguishers for 4-Branch and 8-Branch Generalized Feistel Network
IEEE Access, 2017 In this paper, we present an eight round distinguisher for four-branch type-2 generalized Feistel network (GFN) with double-SP (DSP) functions and two distinguishers for eight-branch type-2 GFN with single-SP (SSP) functions in a known key attack (KKA ...

Algebraic Insights into the Secret Feistel Network [PDF]
Fast Software Encryption Workshop, 2016 We introduce the high-degree indicator matrix HDIM, an object closely related with both the linear approximation table and the algebraic normal form ANF of a permutation. We show that the HDIM of a Feistel Network contains very specific patterns depending on the degree of the Feistel functions, the number of rounds and whether the Feistel functions are

Information leakage of 1-Nested-Feistel network
Journal of Physics: Conference Series, 2018 Impossible differential cryptanalysis is a powerful tool to evaluate the strength of a block cipher structure. In this paper, we investigate the impossible differential property of Nested-Feistel networks, which is a famous block cipher network used in ...

A secure fingerprint hiding technique based on DNA sequence and mathematical function [PDF]
PeerJ Computer ScienceDNA steganography is a technique for securely transmitting important data using DNA sequences. It involves encrypting and hiding messages within DNA sequences to prevent unauthorized access and decoding of sensitive information.
