Understanding the Technological Substitution by Hybrid Modelling Practice: a Methodological Approach

open access: yesChemical Engineering Transactions, 2015
Various novel climate technologies and eco-innovations have already reached a mature state, but they diffuse slowly into the market. Due to this slow process the mitigation of climate change does not take the most effective path.

Chaos-Based Confusion and Diffusion of Image Pixels Using Dynamic Substitution

open access: yesIEEE Access, 2020
The evolution of wireless and mobile communication from 0G to the upcoming 5G gives rise to data sharing through the Internet. This data transfer via open public networks are susceptible to several types of attacks.

Chaos and Cellular Automata-Based Substitution Box and Its Application in Cryptography [PDF]

open access: yes, 2023
Substitution boxes are the key factor in symmetric-key cryptosystems that determines their ability to resist various cryptanalytic attacks. Creating strong substitution boxes that have multiple strong cryptographic properties at the same time is a ...

Algebraic Construction of Powerful Substitution Box

open access: yesInternational Journal of Recent Technology and Engineering (IJRTE), 2020
The development of wireless transmission, day by day contacts the new statures of innovation. Cryptography is one of the procedures used to give security to information streaming over the system by encryption and decryption. Substitution box (S-box) is a one of a kind nonlinear activity in Advanced Encryption Standard (AES), this paper proposed a new ...

Quantum Half and Full Spinning Operator-Based Nonlinear Confusion Component

open access: yesIEEE Access, 2021
The structure of a substitution box (S-box) is one of the principal ideas of the modern encryption techniques. The security of a modern encryption algorithm highly depends on its nonlinear confusion component.

Relating Undisturbed Bits to Other Properties of Substitution Boxes [PDF]

open access: yes, 2015
Recently it was observed that for a particular nonzero input difference to an S-Box, some bits in all the corresponding output differences may remain invariant. These specific invariant bits are called undisturbed bits. Undisturbed bits can also be seen as truncated differentials with probability \(1\) for an S-Box.

Multi-Objective Evolution of Strong S-Boxes Using Non-Dominated Sorting Genetic Algorithm-II and Chaos for Secure Telemedicine

open access: yesIEEE Access, 2022
There exist several performance criteria for cryptographically-strong substitution boxes (S-boxes), which are often conflicting with each other. Constructing S-boxes that satisfy multiple criteria with optimal tradeoffs is one of the challenging tasks ...

A New S-Box Design System for Data Encryption Using Artificial Bee Colony Algorithm

open access: yes, 2023
Securing digital image data is a key concern in today’s information-driven society. Effective encryption techniques are required to protect sensitive image data, with the Substitution-box (S-box) often playing a pivotal role in many symmetric encryption ...

Prognosis of Long‐Term Continuous Renal Replacement Therapy and the Impact of Combined Continuous Intravenous Sodium Infusion Therapy

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Patients requiring long‐term continuous renal replacement therapy (CRRT) generally have poor prognoses. This study evaluated whether adding continuous intravenous sodium infusion (cIVNa) is associated with improved hemodynamics and outcomes in patients undergoing long‐term CRRT for ≥ 7 days.
