Research ArticleOpen accessIn the keywordsComparative Study of Performance in Cryptography Algorithms (Blowfish and Skipjack)Ali Ahmad Milad, Hjh Zaiton Muda, Zul Azri Bin Muhamad Noh, Mustafa Almahdi AlgaetProblem statement: The main goal guiding the design of any encryption algorithm needs to be secured against unauthorized attacks. For all applied applications, performance and the cost of implementations are also important concerns. A data encryption algorithm would not be of much use if it is secure enough but slow in performance because it is a common repetition to embed … …Journal of Computer Science, Vol. 8, Issue 7 · 7 Jul 2012 · 8,018 accessesView PDFCite
Research ArticleOpen accessIn the keywordsNew Approaches to Ancient Crypto-Steganography MethodsA. Joseph Raphael, V. SundaramProblem statement: The requirement and ability to hide information from others has existed in the world for centuries. Cryptography and steganography are the most commonly used techniques for information sharing. The science of securing a data by encryption is cryptography whereas the method of hiding secret messages in other media is Steganography, so that the secret’s very existence is concealed. … …American Journal of Applied Sciences, Vol. 9, Issue 1 · 4 Nov 2011 · 8,110 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBlock Cipher Involving Key Based Random Interlacing and Key Based Random DecompositionK. Anup Kumar, V. U.K. SastryProblem statement: The strength of the block ciphers depend on the degree of confusion and diffusion induced in the cipher. Most of the transformations used for this purpose are well known to every one and can be broken by a crypt analyzer. Therefore, in order to counter attack the crypt analyzer, there is a need for better transformations in addition … …Journal of Computer Science, Vol. 6, Issue 2 · 28 Feb 2010 · 7,004 accessesView PDFCite
Research ArticleOpen accessIn the abstractBlockchain Integrated Distributed Threshold Elliptic Curve Cryptography Framework for Scalable and Secure Cloud Data StorageNaga Swetha Dhulipudi, Balaji SavadamThe development of cloud computing offers scalable processing capabilities, thereby enabling organizations to store and process sensitive data in the cloud. However, it faces crucial security challenges, as existing cryptographic and blockchain systems suffer from poor scalability and centralized key management, which creates a single point of failure and introduces vulnerabilities to both quantum and classical attacks. This research proposes … …Journal of Computer Science, Vol. 22, Issue 11 · 19 Oct 2026 · 395 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis Quantum Implementation of Double AES Cryptography for Secure QR Code GenerationJimmy Wijaya, RojaliData security faces unprecedented challenges due to the rapid advancement of quantum computing technologies, which threaten to compromise foundational classical cryptographic algorithms. This study investigates the quantum implementation of a Double Advanced Encryption Standard (Double AES) scheme for generating secure, tamper-resistant Quick Response (QR) codes. The research encompasses architectural design, quantum circuit construction, and empirical performance evaluation across encryption/decryption execution … …Journal of Computer Science, Vol. 22, Issue 9 · 20 Sep 2026 · 571 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Comparative Computational Efficiency Analysis of LSB and Hybrid Steganographic MethodsDivya Sharma, Chander PrabhaElectronic Medical Images (EMI) are of various types such as X-rays, CT scans, MRIs, etc. EMIs are generally large, but they vary in dimensions and sizes based on the body part to which they belong. Not much research has been done to secure EMIs due to their varied and large sizes, while ensuring their accessibility for real-time transmission. Where access … …Journal of Computer Science, Vol. 21, Issue 10 · 28 Nov 2025 · 2,458 accessesView PDFCite
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 abstractPerformance Analysis of Two Famous Cryptographic Algorithms on Mixed DataEmmanuel Abidemi Adeniyi et al.The rapid development of digital data sharing has made information security a crucial concern in data communication. The information security system heavily relies on encryption methods. These algorithms employ strategies to increase data secrecy and privacy by obscuring the information, which only those parties who have the accompanying key can decode or decrypt. Nevertheless, these methods also use a lot … …Journal of Computer Science, Vol. 19, Issue 6 · 29 May 2023 · 6,020 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Comparative Study of Encryption Methods for Cloud Query ProcessingMo’ath Naser Magableh, Basel AlshaikhdeebQuery cloud process is an interested research study that caught many researchers’ attentions. Several studies have presented different types of encryption in order to encrypt the data prior to being migrated over the cloud. However, there is an essential demand to balance between the time consumption and encryption security. This paper presented a comparative study of encryption methods for query … …Journal of Computer Science, Vol. 15, Issue 11 · 6 Nov 2019 · 7,640 accessesView PDFCite
Review ArticleOpen accessIn the abstractA Proposed an Enhanced Authentication and Dual Encryption Algorithm: Secured Video Transmission in Surgical Tele-TrainingAnil Wagle, Abeer Alsadoon, P.W.C. Prasad et al.Implementation of tele-training for trainee surgeons has been slow to date as current standards of video transmission do not meet requirements for security, speed and clarity for such videos. The aim of this paper is to increase security by providing enhanced authentication as well as improving the overall throughput of the system. The proposed solution consists of a dual encryption … …American Journal of Applied Sciences, Vol. 15, Issue 10 · 28 Dec 2018 · 7,772 accessesView PDFCite
