Research ArticleOpen accessIn the keywordsStrengthening 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 keywordsIntegrated Security Framework for Private Cloud Computing On-PremisePedro Ramos BrandaoDevelopment of a globally integrated framework, intended for implementation in a private on-premise cloud computing framework, structurally based on virtualization technologies, cloud computing, encryption, high availability and redundancy systems, data protection systems, governance, active steering, network monitoring systems, risk analysis and physical infrastructure protection. …Journal of Computer Science, Vol. 16, Issue 12 · 31 Dec 2020 · 7,154 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA New Database Encryption Model Based on Encryption ClassesKarim El Bouchti, Soumia Ziti, Fouzia Omary, Nassim KharmoumData encryption is one of the advanced measures used to consolidate data security inside Databases. It is an essential technique to protect data against theft, disclosure or modification from different typologies of attacks. In this work, we will propose a new database encryption model. It is based on a novel concept called "Encryption Classes". The proposed model is full compared … …Journal of Computer Science, Vol. 15, Issue 6 · 26 Jun 2019 · 7,705 accessesView PDFCite
Research ArticleOpen accessIn the keywordsImplementation of Homomorphic Encryption for Wireless Sensor Networks Integrated with Cloud InfrastructureChristophe Ishimwe Ngabo, Omar El BeqqaliWith the current explosion of cloud services, it is easy for everyone to store the prodigious amount of data on remote servers. On the other hand, service providers are given full access to our information, or in the worst case, can be intercepted by malicious people. The solution is to encrypt the data to make it completely secret. But then, … …Journal of Computer Science, Vol. 15, Issue 2 · 8 Feb 2019 · 7,668 accessesView PDFCite
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 keywordsA Chaotic Block Cipher for Real-Time MultimediaN. Radha, M. VenkatesuluProblem statement: The widespread use of image, audio and video data makes media content protection increasingly necessary and important. We propose a naive approach which treats the multimedia signal to be protected as a text and use proposed encryption design to encrypt the whole data stream. Upon reception, the entire cipher text data stream would be decrypted and playback can … …Journal of Computer Science, Vol. 8, Issue 6 · 27 Apr 2012 · 7,306 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 keywordsNovel Mechanism Control Algorithm for Wired NetworkV. B. Kirubanand, S. PalaniammalProblem statement: A critical issue in wireless network where the data can hack by the person and we add a novel encryption mechanism to protect the data transfer from client to server and vice versa. Approach: We present a queuing model of a client and server that uses for bulk arrival service. The arrival of data requests is assumed to … …Journal of Computer Science, Vol. 7, Issue 9 · 27 Jul 2011 · 6,651 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Novel Enhancement Technique of the Hill Cipher for Effective Cryptographic PurposesA. F.A. Abidin, O. Y. Chuan, M. R.K. AriffinProblem statement: The Hill cipher is the first polygraph cipher which has a few advantages in data encryption. However, it is vulnerable to known plaintext attack. Besides, an invertible key matrix is needed for decryption. It may become problematic since an invertible key matrix does not always exist. Approach: In this study, a robust Hill algorithm (Hill++) has been proposed. … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 8,545 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSingle Core Hardware Module to Implement Partial Encryption of Compressed ImageMamun Bin Ibne Reaz, Md. Syedul Amin, Fazida Hanim Hashim, Khandaker AsaduzzamanProblem statement: Real-time secure image and video communication is challenging due to the processing time and computational requirement for encryption and decryption. In order to cope with these concerns, innovative image compression and encryption techniques are required. Approach: In this research, we have introduced partial encryption technique on compressed images and implemented the algorithm on Altera FLEX10K FPGA device that … …American Journal of Applied Sciences, Vol. 8, Issue 6 · 13 Jun 2011 · 7,379 accessesView PDFCite
