Analysis of Distinguishable Security between the One-Time Password Extraction Function Family and Random Function Family

open access: yesApplied Sciences, 2023
A one-time password is a security system that uses a password that is only used once for authentication, and it is commonly used in multi-factor authentication systems. The process of generating an OTP is very similar to generating pseudorandom sequences

Comb‐Driven Coherent Optical Transmitter for Scalable DWDM Interconnects

open access: yesLaser &Photonics Reviews, EarlyView.
A comb‐driven coherent optical transmitter on a Si/SiN platform enables scalable DWDM interconnects by integrating ultra‐compact microring‐assisted modulators and interleavers. High‐baud coherent signaling achieves 400 Gb/s per wavelength and >$>$1 Tb/s multi‐channel transmission, with projected >$>$10 Tb/s per fiber, offering a path toward energy ...

Serum elemental profile‐based machine learning models for Alzheimer's disease identification and cognitive score prediction

open access: yesNeuroprotection, EarlyView.
Serum elemental profiling combined with machine learning supports exploratory Alzheimer's disease (AD) identification and cognitive score prediction. In this retrospective cross‐sectional study, 874 participants from the BANC‐PUMC, including cognitively normal controls and patients with AD, were analyzed.

Some applications of IFS based on square symmetries

open access: yesNonlinear Analysis, 2012
This paper describes a fractal based method for generating the pseudorandom permutations. We construct an Iterated Function System (IFS) belonging to the class of square symmetries and simulate the pseudorandom walk on a square. In this way some families

Design and Implementation of a Chaotic-Time-Varying Distribution PRNG

open access: yesRevista Elektrón, 2022
Many electronic applications require pseudo-random numbers, in general, to improve their performance. Such is the case of encryption, coding and digital modulation systems.

Enhancing Structural Reliability of Composite Adhesive Joints: An Integrated Experimental‐Numerical‐Machine Learning Framework for Material‐Geometric Co‐Optimization

open access: yesPolymer Composites, EarlyView.
An integrated experimental, numerical, and explainable machine learning framework for the material‐geometric co‐optimization and multi‐objective Pareto design of robust composite adhesive joints. ABSTRACT The reliability of composite adhesive joints is compromised by non‐linear dependencies between material properties and manufacturing uncertainties ...

New Counterexamples to Sequential Composition Adaptive Insecurity

open access: yesIEEE Access
At CRYPTO 2005, Pietrzak demonstrated an intriguing result: the sequential composition of two non-adaptively secure pseudorandom functions does not necessarily imply adaptive security, assuming the decisional Diffie-Hellman (DDH) assumption holds.

Inter‐observer variability is unlikely to explain regional differences in retinopathy of prematurity in Norway

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose To test inter‐observer variation of plus disease diagnoses among Norwegian ophthalmologists and treatment centres. Methods All ophthalmologists in Norway who make individual retinopathy of prematurity (ROP) treatment decisions were invited to grade retinal images using a web‐based image grading platform.
