On Lai–Massey and quasi-Feistel ciphers

Designs, Codes, and Cryptography, 2010
For finite sets \(\mathcal{X}\), \(\mathcal{Y}\) a combiner over \((\mathcal{X},\mathcal{Y})\) is a parameterized family \(\Gamma = {\{ {\Gamma _z}\} _{z \in \mathcal{Y}}}\) of quasigroups \({\Gamma _z}:{\mathcal{X}^2} \to \mathcal{X}\), denote \({\Gamma _z}(x,y) = \Gamma \left[\left[ {x*y|z} \right]\right]\). Let \(b > 1\), \(r > 1\) be fixed integers,

SCENERY: a lightweight block cipher based on Feistel structure

Frontiers of Computer Science, 2021
In this paper, we propose a new lightweight block cipher called SCENERY. The main purpose of SCENERY design applies to hardware and software platforms. SCENERY is a 64-bit block cipher supporting 80-bit keys, and its data processing consists of 28 rounds. The round function of SCENERY consists of 8 4 × 4 S-boxes in parallel and a 32 × 32 binary matrix,

A chaos-based block cipher with Feistel structure

2014 IEEE 13th International Conference on Cognitive Informatics and Cognitive Computing, 2014
In this paper, based on chaotic systems and balanced Feistel network structure, a symmetric block cipher with 256-bit secret key is proposed. The cipher operates on 64-bit plaintext blocks through 16 rounds computing. Within the kernel component of the cipher, i.e., round function F, a hyperchaotic system with four-wing attractors is used to improve ...

Feistel Ciphers

2017
International audience ; This book provides a survey on different kinds of Feistel ciphers, with their definitions and mathematical/computational properties. Feistel ciphers are widely used in cryptography in order to obtain pseudorandom permutations and secret-key block ciphers. In Part 1, we describe Feistel ciphers and their variants. We also give a
