Asymmetric Cryptography

open access: yesIrish Mathematical Society Bulletin, 1988
This short survey article reviews progress in asymmetric (or public-key) cryptography. Knapsack methods are described along with the successful attacks by Shamir and others. The RSA method and certain generalisations are also considered.

PBSFL: Privacy-Preserving and Byzantine-Resilient for Summoning Federated Learning

open access: yesJournal of King Saud University: Computer and Information Sciences
With the expansion of large-scale model applications, a typical division-of-labor federated learning (FL) training paradigm has emerged. This scenario is defined as Summoned Federated Learning (SFL), in which a single task initiator mobilizes cloud ...

Computational and Energy Costs of Cryptographic Algorithms on Handheld Devices [PDF]

open access: yes, 2011
Networks are evolving toward a ubiquitous model in which heterogeneous devices are interconnected. Cryptographic algorithms are required for developing security solutions that protect network activity. However, the computational and energy limitations

The Logic of Large Enough [PDF]

open access: yes, 2010
In this paper we explore the "for large enough" quantifier, also known as "all but finitely many", which plays a central role in asymptotic reasoning, as used for example in complexity theory and cryptography.

Optimal colored threshold visual cryptography schemes [PDF]

open access: yes, 2005
Visual cryptography schemes allow the encoding of a secret image into n shares which are distributed to the participants. The shares are such that only qualified subsets of participants can visually recover the secret image.

High-Chroma Visual Cryptography Using Interference Color of High-Order Retarder Films [PDF]

open access: yes, 2015
Visual cryptography can be used as a method of sharing a secret image through several encrypted images. Conventional visual cryptography can display only monochrome images.

IAGF: a dual-path collaborative inconsistency-aware global fusion network for multimodal sarcasm detection

open access: yesJournal of King Saud University: Computer and Information Sciences
Multimodal sarcasm detection aims to identify ironic intent from textual and visual information, with the core challenge lying in capturing semantic inconsistencies between different modalities.

Liver organoids: modelling complexity in homeostasis and disease

open access: yesFEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

Cheating in visual cryptography

open access: yes, 2014
A secret sharing scheme allows a secret to be shared among a set of participants, P, such that only authorized subsets of P can recover the secret, but any unauthorized subset cannot recover the secret.

Efficient algorithms for pairing-based cryptosystems [PDF]

open access: yes, 2002
We describe fast new algorithms to implement recent cryptosystems based on the Tate pairing. In particular, our techniques improve pairing evaluation speed by a factor of about 55 compared to previously known methods in characteristic 3, and attain ...
