Research ArticleOpen accessPhrase in the titleRandomness Analysis on Lightweight Block Cipher, PRESENTIsma Norshahila Binti Mohammad Shah, Eddie Shahril Bin IsmailLightweight cryptography is an area of current research conducted by academicians and cryptographic experts to ensure the security of data in limited-resource devices such as RFID tags, medical and health care devices and sensor networks. One of the lightweight algorithms built is the PRESENT algorithm. To this day, PRESENT has been a reference for lightweight block cipher algorithms and is … …Journal of Computer Science, Vol. 16, Issue 11 · 26 Nov 2020 · 6,889 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleRandomness Analysis of DES Ciphers Produced with Various Dynamic ArrangementsMalik Qasaimeh, Raad S. Al-QassasOver the past few years, researchers have devoted efforts to enhance the original DES encryption algorithm. These enhancements focus on improving multiple perspectives of the algorithm through enhancing its internal components to deliver a robust DES variant against different kinds of typical attacks such as linear and differential crypto analysis, in addition to the newly evolved attacks such as differential … …Journal of Computer Science, Vol. 13, Issue 12 · 15 Dec 2017 · 7,161 accessesView PDF Cite

Research ArticleOpen accessIn the abstractStrengthening Image Security with Unimodular Hill Cipher and Advanced Encryption StandardSamsul Arifin, Dwi Wijonarko, Monica Mayeni Manurung et al.Digital data security has become increasingly important with the growth of digital image usage, which often contains sensitive information. This study aims to enhance the security of digital images by combining Unimodular Hill Cipher (UHC) and Advanced Encryption Standard (AES) methods. UHC, a matrix-based symmetric encryption algorithm, is used for image matrix encryption, while AES provides an additional layer of … …Journal of Computer Science, Vol. 21, Issue 5 · 22 Apr 2025 · 5,408 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Multiple-Chaotic Approach for SteganographyHaneen H. Alwan, Zahir M. HussainIn a recent work, chaos has been utilized to modify addresses of message bits while hidden in a cover image. In this study, we extend the above technique to include multiple chaotic maps for increased security. Three systems have been modified using chaotic-address mapping for image steganography in the spatial domain. The first system, the well-known LSB technique, is based … …Journal of Computer Science, Vol. 15, Issue 10 · 17 Oct 2019 · 7,427 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThermodynamics, Non-Linear Isotherms, Statistical Modeling and Optimization of Phosphorus Adsorption from WastewaterAkinpelu Kamoru BabayemiPalm Kernel Shell (PKN), an eco-friendly biomass, was carbonized and activated for the removal of phosphorus from wastewater through batch adsorption process. The studies evaluate the effects of pH, particle size, dosage and contact time on the adsorption capacity of the prepared adsorbent. The equilibrium concentration data and the amount of adsorption were described using non-linear regression analysis of the … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 19 Nov 2016 · 7,512 accessesView PDF Cite
