Improving the Security of Video Embedding Using the CFP-SPE Method

Journal of Engineering, 2022
With the amount of data being transferred on a daily basis, it is becoming increasingly dangerous to save data on the Internet in the face of intruders or hackers. This study paper is one of the most effective ways to transmit information in a secure and

Sub‐Terahertz Memristor Switches Using MoS2 by Liquid–Liquid Interface Assembly

Advanced Science, EarlyView.
This work introduces application‐ready sub‐terahertz memristor switches fabricated from electrochemically exfoliated MoS2 nanosheets assembled at a liquid–liquid interface. The devices exhibit robust unipolar resistive switching, low insertion loss, and high isolation across 10–110 GHz.

Femtosecond‐Laser‐Induced Physical Unclonable Random Maze Structure for Storage‐Free Encryption

Advanced Science, EarlyView.
Femtosecond‐laser‐induced gold random maze structures serve as multimodal physical unclonable functions for storage‐free encryption. Their stochastic optical, electrical, and Raman responses are generated by plasmon‐assisted Marangoni formation and converted into AES‐compatible keys without permanent secret‐key storage, offering a portable route toward

"Share your data, keep your secrets." [PDF]

Proceedings of the 2004 ACM SIGMOD international conference on Management of data, 2004
The next generation of services will not be restricted to the boundaries of a given network. This is called convergence! Land-line telephony, wireless telephony, instant messaging, Web, etc. now form a converged network where applications can be deployed.

A Novel IDO1/NE Dual Inhibitor, IMM‐H018 Prevents the Primary and Secondary Sepsis and Ameliorates the Kidney Injury Through Inhibiting the Cytokine Storm and Microthrombosis, and Reversing Immunosuppression

Advanced Science, EarlyView.
IMM‐H018, a dual IDO1/NE inhibitor, demonstrates potent therapeutic efficacy in sepsis by simultaneously targeting excessive inflammation and immune dysfunction. It prevents both primary and secondary sepsis through anti‐inflammatory, immune‐restoring, and renoprotective mechanisms, reducing organ damage, improving immune homeostasis, preserving kidney

(k, n) secret base64 data sharing scheme using simple modular arithmetic

Journal of King Saud University: Computer and Information Sciences
A (k, n) secret sharing (SS) is a threshold scheme that shares secret multimedia data into n sub-secrets (called shares). When any k or more shares are collected, the secret is recovered.

Anti-attacks encryption algorithm based on DNA computing and data encryption standard

Alexandria Engineering Journal, 2022
Data Encryption Standard (DES) is the first 56-bits secret-key standard that is widely used as a symmetric-key 64-bits block encryption/decryption algorithm. Unfortunately, the rapid increase in computing power makes it possible to find the required bits

Nanowires Reinforce Oriented Macroporous Aerogels for Rapid Uranium Removal from Acidic Radioactive Wastewater

Advanced Science, EarlyView.
A “reinforced concrete” structural aerogel with directional microchannels is engineered for rapid uranium capture. The interconnected architecture enables ultrafast water permeation, and the nanowire reinforcement yields a 70‐fold increase in mechanical strength.

Multi-Bit Data Hiding Scheme for Compressing Secret Messages

Applied Sciences, 2015
The goal of data hiding techniques usually considers two issues, embedding capacity and image quality. Consequently, in order to achieve high embedding capacity and good image quality, a data hiding scheme combining run-length encoding (RLE) with multi ...
