Towards Analyzable Design Paradigms for Chaos-Based Cryptographic Primitives
Journal of Cybersecurity and PrivacyAlthough many chaos-based cryptosystems have been proposed over the past decade, they have yet to gain traction in real-world applications. A key reason for this is that most designs rely on security through obscurity, with unnecessarily complex ...

An Efficient Ontology‐Based Semantic Interoperability Using MSGO‐RNN in Cloud Computing
Journal of Optimization, Volume 2024, Issue 1, 2024.Semantic interoperability (SI) is defined as the capability of interpreting the nature of the information exchanged inside cloud computing (CC). For SI, ontology is selected as a solution. A hierarchical structure is offered by an ontology that comprises semantic relations between the application and the cloud server (CS). Even though different methods

Energy Efficient Encryption Algorithm for Low Resources Devices
ARCHive-SR, 2019 Saving energy is one of the most challenging aspects in the wireless network devices. Such devices are connected together to perform a certain task. A well-known example of these structures is the Wireless Sensor Network (WSN).

New Algorithm for Exhausting Optimal Permutations for Generalized Feistel Networks
, 2022 The Feistel construction is one of the most studied ways of building block ciphers. Several generalizations were proposed in the literature, leading to the Generalized Feistel Network (GFN) construction, in which the round function operates on each pair of blocks in parallel until all branches are permuted.

Deck-Based Wide Block Cipher Modes and an Exposition of the Blinded Keyed Hashing Model
IACR Transactions on Symmetric Cryptology, 2020 We present two tweakable wide block cipher modes from doubly-extendable cryptographic keyed (deck) functions and a keyed hash function: double-decker and docked-double-decker.

Refined Probability of Differential Characteristics Including Dependency Between Multiple Rounds
IACR Transactions on Symmetric Cryptology, 2017 The current paper studies the probability of differential characteristics for an unkeyed (or with a fixed key) construction. Most notably, it focuses on the gap between two probabilities of differential characteristics: probability with independent S-box

Distinguishing attack on five-round Feistel networks
Electronics Letters, 2003 Recently it was shown (by J. Patarin) how to distinguish a general five-round Feistel network from a random permutation using (23n/2) chosen plaintexts or (27n/4) known plaintexts. The present authors report improvement of these results and a distinguisher is presented which uses roughly 2n chosen plaintexts or roughly 23n/2 known plaintexts.

SAT-based cryptanalysis of modified versions of Feistel Network [PDF]
, 2011 It is well known that Feistel Network (FN) is the foundation of many symmetric ciphers used in practice. In this paper we present some remarks and experimental results on SAT based cryptanalysis of several modified versions of FN.

Practically Secure Feistel Ciphers [PDF]
, 1994 In this paper we give necessary design principles to be used, when constructing secure Feistel ciphers. We introducee a new concept, practical security against linear and differential attacks on Feistel ciphers.

THE AVALANCHE EFFECT IN ENCRYPTION ALGORITHMS BASED ON THE DISCRETE CHAOTIC MAPS
Доклады Белорусского государственного университета информатики и радиоэлектроники, 2019 The avalance effect has been investigated in an encryption algorithm being developed on the basis of the discrete chaotic maps. The avalanche effect has been analyzed in a discrete tent map and in the basic transformation based on the Feistel network ...
