Shapeless Quasigroups Derived by Feistel Orthomorphisms [PDF]

, 2012
Shapeless quasigroups are needed for cryptography purposes. In this paper, we construct shapeless quasigroups by the diagonal method from orthomorphisms over abelian groups. We use generalizations of Feistel networks as orthomorphisms.

Ice‐Ocean Interactions on Ocean Worlds Influence Ice Shell Topography

Journal of Geophysical Research: Planets, Volume 129, Issue 2, February 2024.
Abstract The freezing point of water is negatively dependent on pressure; therefore in any ocean without external forcing it is warmest at the surface and grows colder with depth. Below floating ice on Earth (e.g., ice shelves or sea ice), this pressure dependence combines with gradients in the ice draft to drive an ice redistribution process termed ...

A New (Related‐Key) Neural Distinguisher Using Two Differences for Differential Cryptanalysis

IET Information Security, Volume 2024, Issue 1, 2024.
At CRYPTO 2019, Gohr showed the significant advantages of neural distinguishers over traditional distinguishers in differential cryptanalysis. At fast software encryption (FSE) 2024, Bellini et al. provided a generic tool to automatically train the (related‐key) differential neural distinguishers for different block ciphers. In this paper, based on the

Optimized SM4 Hardware Implementations for Low Area Consumption

IET Information Security, Volume 2024, Issue 1, 2024.
The SM4 block cipher is standardized in ISO/IEC, and it is also the national standard of commercial cryptography in China. In this paper, we propose two new techniques called “split‐and‐join” and “off‐peak and stagger” to make SM4 more applicable to resource‐constrained environments.

Superposition Attacks on Pseudorandom Schemes Based on Two or Less Permutations

IET Information Security, Volume 2024, Issue 1, 2024.
We study quantum superposition attacks against permutation‐based pseudorandom cryptographic schemes. We first extend Kuwakado and Morii’s attack against the Even–Mansour cipher and exhibit key recovery attacks against a large class of pseudorandom schemes based on a single call to an n‐bit permutation, with polynomial O(n) (or O(n2), if the concrete ...

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

Modified Generalized Feistel Network Block Cipher for the Internet of Things

, 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 ...

Cryptanalysis of a Generalized Unbalanced Feistel Network Structure [PDF]

, 2012
This paper reevaluates the security of GF-NLFSR, a new kind of generalized unbalanced Feistel network structure that was proposed at ACISP 2009. We show that GF-NLFSR itself reveals a very slow diffusion rate, which could lead to several distinguishing ...

Quantum Distinguishing Attacks against Type-1 Generalized Feistel Ciphers [PDF]

, 2019
A generalized Feistel cipher is one of the methods to construct block ciphers, and it has several variants. Dong, Li, and Wang showed quantum distinguishing attacks against the $(2d-1)$-round Type-1 generalized Feistel cipher with quantum chosen ...
