A Novel Chaotic Block Image Encryption Algorithm Based on Deep Convolutional Generative Adversarial Networks

open access: yesIEEE Access, 2021
This paper proposes a novel chaotic block image encryption algorithm based on deep convolutional generative adversarial networks (DCGANs), quaternions, an improved Feistel network, and an overall scrambling and diffusion mechanism.

Automated design of a lightweight block cipher with Genetic Programming [PDF]

open access: yes, 2008
In this paper, we present a general framework for the automated design of cryptographic block ciphers by using Genetic Programming. We evolve highly nonlinear and extremely efficient functions that can be used as core components of any cryptographic ...

A new quantum cryptanalysis method on block cipher Camellia

open access: yesIET Information Security, 2021
Symmetric cryptography is expected to be quantum safe when long‐term security is needed. Kuwakado and Morii gave a 3‐round quantum distinguisher of the Feistel cipher based on Simon's algorithm.

Extended Generalized Feistel Networks using Matrix Representation to Propose a New Lightweight Block Cipher: Lilliput [PDF]

open access: yes, 2015
International audienceWhile Generalized Feistel Networks (GFNs) have been widely studied in the literature as a building block of a block cipher, we recall in this paper the results of [1] where a unified vision to easily represent them through a matrix ...

Practically secure Feistel ciphers [PDF]

open access: yesDAIMI Report Series, 1994
In this paper we give necessary design principles to be used, when constructing secure Feistel ciphers. We introducee a new concept, <strong> practical security</strong> against linear and differential attacks on Feistel ciphers. We give examples of such Feistel ciphers (practically) resistant to differential attacks, linear attacks and ...

An Image Encryption Method Based on the Feistel Network and Dynamic DNA Encoding

open access: yesIEEE 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.
