A Proposal of a New Chaotic Map for Application in the Image Encryption Domain

open access: yes, 2023
Several chaos-based image encryption schemes have been proposed in the last decade. Each encryption scheme has pros and cons regarding its speed, complexity, and security.

Image encryption by chaos mixing

open access: yesIET Image Processing, 2016
The need for image encryption is constantly on the rise and has led to the emergence of many techniques in literature. In recent years, many chaos‐based encryption techniques have developed with more or less success. In this study, we suggest one such approach using two oscillators.

Using discrete-time hyperchaotic-based asymmetric encryption and decryption keys for secure signal transmission [PDF]

open access: yes, 2014
In this paper, a framework for the synchronization of two non-identical discrete-time hyperchaotic systems, namely the 3D Baier-Klein and the 3D Hitzel-Zele maps, based on the use of hybrid output feedback concept and aggregation techniques, is employed ...

A flexible and visually meaningful multi-image compression, encryption and hiding scheme based on 2D compressive sensing

open access: yesHeliyon, 2023
Background: Encrypting plain images into noise-like cipher images is a common method in image encryption. However, when noise-like images appear in public networks, they are more likely to attract attention and suffer more cryptanalysis.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.
