A New Symmetric Key Cryptosystem Based on Feistel Network: Parallel Dependent Feistel Network (PDFN)
Lecture Notes of the Institute for Computer Sciences, Social-Informatics and Telecommunications Engineering, 2012In this paper a new Symmetric Key Cryptosystem, based on Feistel Networks has been proposed. The Cryptosystem demonstrates a few effective features like variable size key, variable size plain text encryption depending on data and key, padding by random variables etc. The cryptosystem is designed to be efficient on processors using simple operations.

Modified Generalized Feistel Network Block Cipher for the Internet of Things
Symmetry, 2023 With the advent of the Internet-of-Things (IoT) technologies, millions of low-resource devices are constantly used at the network’s edge. As a result, the large amount of private and sensitive data generated by these devices must be securely ...

Utilizing LFSR and Feistel networks in image encryption
2013 IEEE 20th International Conference on Electronics, Circuits, and Systems (ICECS), 2013This paper presents a new encryption scheme based on the combination between Linear Feedback Shift Register (LFSR) and generalized Feistel networks (GFN). The construction of each GFN depends on Substitution Boxes (S-Boxes) and its operation requires a key. The encryption key length is dynamic and can be controlled via the initial values of the LFSR, S-

Improved Attacks on Extended Generalized Feistel Networks
2016In SAC 2013, Berger et al. defined Extended Generalized Feistel Networks (EGFN) and analyzed their security. They proposed designs with 8 or 16 branches. This class of schemes is well-suited for cryptographic applications. Using the minimal number of active S-boxes, the authors showed that for 64-bits messages divided into 8 branches, at least seven ...

Generic Attacks on Feistel Networks with Internal Permutations
2009In this paper, we describe generic attacks on Feistel networks with internal permutations, instead of Feistel networks with internal functions as designed originally. By generic attacks, we mean that in these attacks the internal permutations are supposed to be random.

A simple network of small s-boxes can be proven secure against differential and linear cryptanalysis. Upperbounds of the differential probabilities and the linear correlations are derived for a generalized Feistel network having 1, 2, 3 or 4 s-boxes in parallel per round. It is conjectured that the results hold in general.
