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 PDFCite
Research ArticleOpen accessIn the abstractHybrid Optimization to Trust Enhanced Secure Routing Optimization with IABC and CGWAA for MANETYuvaraja Panneer Selvam, Suganthi PerumalRouting in Mobile Ad Hoc Networks (MANET) presents significant challenges due to the dynamic nature of network topology. Optimal route selection and efficient route discovery are matched by effective routing in MANET. This study proposes a Hybrid Optimization to Trust-Enhanced Secure Routing Optimization (HO-TESRO) designed to address these challenges in IoT environments by integrating metrics such as link stability, bandwidth, … …Journal of Computer Science, Vol. 21, Issue 4 · 19 Mar 2025 · 4,983 accessesView PDFCite
Research ArticleOpen accessIn the abstractIrregular Reflexive Labeling and Elementary Row Operations for Enhanced Biometric Image EncryptionIka Hesti Agustin, Dafik et al.A total k-labeling defined the function fe: E(G) → {1, 2, …, ke} and fv: V(G) → {0, 2, …, 2kv}, where, k = max {ke, 2kv}. For graph G, the total k-labeling is called an edge (or a vertex) irregular reflexive k-labeling if the condition of every two different edges (or vertices) has different weights. The smallest value of … …Journal of Computer Science, Vol. 20, Issue 12 · 20 Nov 2024 · 4,149 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 · 4,725 accessesView PDFCite
Research ArticleOpen accessIn the abstractPrimary Color Based Numerous Image Creation in Visual Cryptography with the Help of Grasshopper Algorithm, Artificial Neural Network and Elliptic Curve CryptographySurajit Goon, Debdutta Pal, Souvik DihidarThe two primary restrictions of visual cryptography methods, contract, and security are well-known. Visual cryptography is considered secure if no share reveals information about the secure picture and this image is unreachable when shares are combined. Recursion can be used in a visual cryptography method to ensure the integrity of both arguments. Sometimes, the many shares are generated illogically in … …Journal of Computer Science, Vol. 18, Issue 5 · 19 May 2022 · 6,279 accessesView PDFCite
