Research ArticleOpen accessIn the keywordsPERFORMANCE ANALYSIS OF IMAGE SECURITY BASED ON ENCRYPTED HYBRID COMPRESSIOND. Ramkumar, I. Jacob RaglendIn this research, we propose an image security scheme using hybrid compression techniques. In this scheme, the data is being provided two-fold security by both encryption stage and hiding stage. The data/message which has to be secured undergoes encryption technique at the initial stage. In this stage, the permutation algorithm is employed which requires a pair of numbers as a … …American Journal of Applied Sciences, Vol. 11, Issue 7 · 26 Apr 2014 · 6,712 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Password-Based Key Derivation Algorithm Using the KBRP MethodShakir M. Hussain, Hussein Al-BahadiliThis study presents a new efficient password-based strong key derivation algorithm using the key based random permutation the KBRP method. The algorithm consists of five steps, the first three steps are similar to those formed the KBRP method. The last two steps are added to derive a key and to ensure that the derived key has all the characteristics of … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 6,886 accessesView PDFCite
Research ArticleOpen accessIn the keywordsIrregular Class of Multistage Interconnection Network in Parallel ProcessingSandeep Sharma, K. S. Kahlon, P. K. Bansal, Kawaljeet SinghA major problem in designing a large-scale parallel and distributed system was the construction of an Interconnection Network (IN) to provide inter-processor communication. One of the biggest issues in the development of such a system was the development of an effective architecture and algorithms that have high reliability, give good performance (even in the presence of faults), low cost, low … …Journal of Computer Science, Vol. 4, Issue 3 · 31 Mar 2008 · 7,057 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Optimized Multi-Layer Perceptron Framework for Detecting and Classifying IoT AttacksSanchit Vashisht, Shalli RaniThe Internet of Things (IoT) is revolutionizing industries by connecting billions of smart devices, enabling automation and information exchange. The expansion of IoT ecosystems has simultaneously increased the surface area for cyberattacks. These environments are particularly vulnerable to a wide range of threats, such as Distributed Denial-of-Service (DDoS), poisoning, brute-force SSH intrusions, and various network reconnaissance techniques. The dynamic nature … …Journal of Computer Science, Vol. 21, Issue 12 · 11 Feb 2026 · 1,333 accessesView PDFCite
Research ArticleOpen accessIn the abstractSecure Symmetric Block Cipher Design for Encrypting the Bitcoin Wallets in Cryptocurrencies ApplicationsOmar A. Dawood, Othman I. Hammadi, Falath M. MohammedThis paper proposes a new symmetric secret-key cipher for construction of block cipher model. This new approach is considered as a smart step that can be applied to the long process research of modern designing methods used in developing earlier symmetric algorithms. The present cipher can encrypt block lengths of 128-bit by employing Substitution-Permutation Network (SPN) structure. The present cipher … …Journal of Computer Science, Vol. 15, Issue 5 · 1 Jun 2019 · 8,412 accessesView PDFCite
Research ArticleOpen accessIn the abstractSegmented Block Cipher Algorithm Based on ASCII-Codes ManeuverShadi Rasheed Masadeh, Hamza Abbass Al-SewadiDue to their complexity, computation time and power requirement, the secure and widely used cryptographic systems such as 3DES and AES may not be considered suitable for applications like mobile and remote sensing of sensitive data. Therefore, secure but less complicated algorithms for data encryption are still sought. This paper suggests a new Segmented Block Cipher Algorithm (SBCA) is a … …Journal of Computer Science, Vol. 13, Issue 12 · 15 Dec 2017 · 6,899 accessesView PDFCite
Research ArticleOpen accessIn the abstractON SELF-INVERSE BINARY MATRICES OVER THE BINARY GALOIS FIELDAli Muhammad Ali Rushdi, Fares Ahmad Muhammad GhalebAn important class of square binary matrices over the simplest finite or Galois Field GF(2) is the class of involutory or Self-Inverse (SI) matrices. These matrices are of significant utility in prominent engineering applications such as the study of the Preparata Transformation or the analysis of synchronous Boolean Networks. Therefore, it is essential to devise appropriate methods, not only for … …Journal of Mathematics and Statistics, Vol. 9, Issue 3 · 4 Sep 2013 · 7,248 accessesView PDFCite
Research ArticleOpen accessIn the abstractGC-MS Analysis and PLS-DA Validation of the Trimethyl Silyl-Derivatization TechniquesKamalrul Azlan Azizan, Syarul Nataqain Baharum, Habtom W. Ressom, Normah Mohd. NoorProblem statement: Comparison and validation analysis of the conventional and power-adjusted Microwave-Assisted (MA) techniques of TMS derivatization using Gas Chromatography-Mass Spectrometry (GC-MS) and Multivariate Analysis (MVA) of Partial Least Squares Analysis (PLS-DA). Further improvement of the conventional technique using vigorous shaking was tested and analyzed. Approach: Cross-validation and response permutation test of PLS-DA and S-plot of Orthogonal Partial Least Squares … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 4 Jun 2012 · 10,320 accessesView PDFCite
Research ArticleOpen accessIn the abstractA 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 abstractOmega Network Hash ConstructionChai Wen Chuah, Azman SamsudinProblem statement: Cryptographic hash functions are important cryptographic primitives. They are commonly used for data integrity checking and data authentication. Most of the cryptographic hash functions are based on the Merkle-Damgård construction. The basic Merkle-Damgård construction runs over the input sequentially, which can lead to problems when the input size is large since the computation time increases linearly. Approach: Therefore, … …Journal of Computer Science, Vol. 5, Issue 12 · 31 Dec 2009 · 7,123 accessesView PDFCite
