KFC – The Krazy Feistel Cipher [PDF]
International Conference on the Theory and Application of Cryptology and Information Security, 2006 We introduce KFC, a block cipher based on a three round Feistel scheme. Each of the three round functions has an SPN-like structure for which we can either compute or bound the advantage of the best d-limited adaptive distinguisher, for any value of d.

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.

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 transported,

A New Cipher Based on Feistel Structure and Chaotic Maps
مجلة بغداد للعلوم, 2019 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 ...

Yoyo Cryptanalysis Against Reduced-Round L-Feistel Structure for Recovering the Secret Components
IET Information SecurityL-Feistel structure is a new iterative block cipher structure and unifies the Feistel structure and the Lai–Massey structure while maintaining the similarity of encryption and decryption. In this study, we present the first yoyo cryptanalysis against the

Truncated Differential Attacks on Contracting Feistel Ciphers
IACR Transactions on Symmetric Cryptology, 2022 We improve truncated differential attacks on t-branch contracting Feistel ciphers with a domain size of Nt. Based on new truncated differentials, a generic distinguisher for t2 + t − 2 rounds using O(Nt−1) data and time is obtained.

Generalized Feistel Structures Based on Tweakable Block Ciphers
IACR Transactions on Symmetric Cryptology, 2022 A generalized Feistel structure (GFS) is a classical approach to construct a block cipher from pseudorandom functions (PRFs). Coron et al. at TCC 2010 instantiated a Feistel structure with a tweakable block cipher (TBC), and presented its provable ...

10-Round Feistel is Indifferentiable from an Ideal Cipher [PDF]
Lecture Notes in Computer Science, 2016 We revisit the question of constructing an ideal cipher from a random oracle. Coron et al.i¾?Journal of Cryptology, 2014 proved that a 14-round Feistel network using random, independent, keyed round functions is indifferentiable from an ideal cipher, thus demonstrating the feasibility of such a transformation. Left unresolved is the number of rounds of

On Boomerang Attacks on Quadratic Feistel Ciphers
IACR Transactions on Symmetric Cryptology, 2023 The recent introduction of the Boomerang Connectivity Table (BCT) at Eurocrypt 2018 revived interest in boomerang cryptanalysis and in the need to correctly build boomerang distinguishers.
