Research ArticleOpen accessIn the abstractImplementation of a Logistic Map to Calculate the Bits Required for Digital Image Steganography Using the Least Significant Bit (LSB) MethodWikky Fawwaz Al Maki, Indra Bayu Muktyas, Samsul Arifin et al.The LSB method in steganography usually only uses the last bit or the last few bits that are the same for all pixels. This is very easy to solve by using a bitwise shift left operation so that the last bit becomes the leading bit (MSB). Some techniques combine steganography and cryptography through two different processes. In this study, a … …Journal of Computer Science, Vol. 19, Issue 6 · 11 May 2023 · 5,800 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesigning the Future: A Blockchain-Based Framework for Transparent and Secure ElectionsJayesh Solanki, Divyakant MevaBlockchain-based electronic voting systems have been identified as a solution to enhance the transparency, security, and efficiency of modern electoral processes. However, the existing system has three major problems, which include scalability, privacy issues, and cybersecurity attacks. The researcher proposed an innovative solution to develop an electronic voting system with enhanced security, scalability, and transparency of voters' information. This paper … …Journal of Computer Science, Vol. 22, Issue 6 · 16 Jun 2026 · 1,301 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimized Vehicle Insurance Claim and Settlement Procedures Using IOT Sensors on a Blockchain-Based PlatformPreeti Sharma, Meenakshi Malik, Chander Prabha et al.The conventional vehicle insurance claim and settlement landscape is characterised by significant inefficiencies, including cumbersome claim submissions, arbitrary damage assessments, and susceptibility to fraudulent activities. These problems lead to a longer processing time, higher operational cost to the insurers and a reduction in policyholder satisfaction. To address these important challenges, this study proposes a streamlined vehicle insurance claims system that … …Journal of Computer Science, Vol. 22, Issue 3 · 26 Mar 2026 · 1,640 accessesView PDFCite
Research ArticleOpen accessIn the abstractRandomness 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 · 6,896 accessesView PDFCite
Research ArticleOpen accessIn the abstractImprovement of Menezes-Vanstone Elliptic Curve Cryptosystem Based on Quadratic Bézier Curve TechniqueDua M. Ghadi, Adil AL-RammahiCryptography is one of the most important applications and widely used in our life especially in the information security that needed by many government institutions, banks, communications and others to keep data over internet and other transportations that it is ensure safety of transfers between the sender and the recipient. The most important system in cryptography is public key cryptography … …Journal of Computer Science, Vol. 16, Issue 5 · 4 Jun 2020 · 8,223 accessesView PDFCite
Research ArticleOpen accessIn the abstractFeatures of the Security System Development of a Computer Telecommunication NetworkLeonid Chervyakov, Tagirbek Aslanov, Dmitry Polezhaev, Viktor LysenkoGlobal computer networks have enabled ordinary users, companies, organizations and medical institutions to gain virtually unlimited access to data arrays. Therefore, developing systems capable of ensuring the good performance and secure operation of a standard Computer Telecommunication Network (CTN) has become one of the most pressing tasks demanded in the medical industry. Consequently, this study aims to create an ordered … …Journal of Computer Science, Vol. 20, Issue 9 · 20 Jun 2024 · 4,729 accessesView PDFCite
Research ArticleOpen accessIn the abstractTPAL: A Protocol for Node Authentication in IoTMohamad Faiz Razali, Mohd Ezanee Rusli, Norziana Jamil, Salman YussofSecure communication in Low power and Lossy Network (LLN) requires the authentication of the identities of nodes for that node to join the network. Since LLN may consist of many different nodes, where some nodes may contain sensitive and subtle information such as military data, monitoring data, or health data, that node needs to be authenticated before it can deliver … …Journal of Computer Science, Vol. 14, Issue 10 · 30 Oct 2018 · 7,031 accessesView PDFCite
Research ArticleOpen accessIn the abstractNew Algorithm for Digital Video EncryptionSamsul Arifin, Wihikanwijna, Tuga Mauritsus et al.This research aims to propose a safe digital video data alternative employing symmetric cryptography and an encryption technique using Partition. The Hill Cipher method requires a square key matrix with an inverse modulo the unimodular matrix is one of the unique matrices with an inverse.
