Research ArticleOpen accessIn the abstractTesting Image Encryption by Output Feedback (OFB)Yas A. AlsultannyWhen it is necessary to securely transmit data in open networks, the encryption must be performed. Most of the cryptographic algorithms were mainly developed for text data. Unfortunately, algorithms those are good for textual data might not suitable for image. The OFB mode of encryption implemented to test five images of different resources, by using three combinations (schemes): a combination … …Journal of Computer Science, Vol. 4, Issue 2 · 28 Feb 2008 · 7,193 accessesView PDFCite
Research ArticleOpen accessIn the abstractHiding a Large Amount of Data with High Security Using Steganography AlgorithmNameer N. EL-EmamThis study deals with constructing and implementing new algorithm based on hiding a large amount of data (image, audio, text) file into color BMP image. We have been used adaptive image filtering and adaptive image segmentation with bits replacement on the appropriate pixels. These pixels are selected randomly rather than sequentially by using new concept defined by main cases with … …Journal of Computer Science, Vol. 3, Issue 4 · 30 Apr 2007 · 8,617 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Backpropagation Neural Network for Computer Network SecurityKhalil ShihabIn this paper, an efficient and scalable technique for computer network security is presented. On one hand, the decryption scheme and the public key creation used in this work are based on a multi-layer neural network that is trained by backpropagation learning algorithm. On the other hand, the encryption scheme and the private key creation process are based on Boolean … …Journal of Computer Science, Vol. 2, Issue 9 · 30 Sep 2006 · 19,535 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Large Block Cipher Using Modular Arithmetic Inverse of a Key Matrix and Mixing of the Key Matrix and the PlaintextV. U.K. Sastry, S. Udaya Kumar, A. Vinaya babuIn this paper, we have developed a block cipher by applying an iterative method. In the process of encryption, we have used a key matrix (K) in which all the elements are binary bits. In the process of decryption, we have utilized the modular arithmetic inverse (K-1). In the process of encryption, the elements of the plaintext and the elements … …Journal of Computer Science, Vol. 2, Issue 9 · 30 Sep 2006 · 6,796 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Type of Network Security Protocol Using Hybrid Encryption in Virtual Private NetworkingE. Ramaraj, S. KarthikeyanToday wireless communications is acting as a major role in networks. Through year-end 2006, the employee's ability to install unmanaged access points will result is more than 50% of enterprises exposing sensitive information through the wireless virtual private networks (VPN). It enables you to send the data between two computers across a shared or public network in a manner that … …Journal of Computer Science, Vol. 2, Issue 9 · 30 Sep 2006 · 6,788 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Defense Mechanism for Differential Power Analysis Attack in AESJ. Vijaya, M. RajaramIn modern wireless communication world, the security of data transfer has been the most challenging task. In embedded system, AES is the most extensively used cryptographic algorithm in practice. But its functionality has been disrupted by the DPA attack. There have been several countermeasures to tackle those attacks, but this study proposes variably a new measure to defend this DPA … …Journal of Computer Science, Vol. 11, Issue 2 · 1 Sep 2014 · 7,257 accessesView PDFCite
Research ArticleOpen accessIn the abstractIMPLEMENTATION OF CENTRAL QUEUE BASED REALTIME SCHEDULER FOR MULTIPLE SOURCE DATA STREAMINGV. Kaviha, V. Kannan, S. RaviReal-time data packet sources are required to remain robust against different security threats. This study proposes a real-time secure scheduling strategy for data transmission to enhance the communication throughput and reduce the overheads. The proposed system combines real-time scheduling with security service enhancement, error detection and realtime scheduler based on EDF algorithm using uc/os-II real time operating system, implemented on … …Journal of Computer Science, Vol. 10, Issue 9 · 22 Apr 2014 · 6,381 accessesView PDFCite
Research ArticleOpen accessIn the abstractA NOVEL APPROACH FOR INFORMATION SECURITY IN AD HOC NETWORKS THROUGH SECURE KEY MANAGEMENTS. Suma Christal Mary, M. PallikondaRajasekaran, Y. ChrisbinJeevaAd hoc networks provide flexible and adaptive networks with no fixed infrastructure and dynamic topology. Owe to the vulnerability nature of ad hoc network, there are lots of security threats that diminish the development of ad hoc networks. Therefore, to provide security for information of users and to preserve their privacy, it becomes mandatory to use cryptographic techniques to set … …Journal of Computer Science, Vol. 9, Issue 11 · 2 Oct 2013 · 6,690 accessesView PDFCite
Research ArticleOpen accessIn the abstractMESSAGE AUTHENTICATION CODE BASED SECURE GROUP KEY MANAGEMENT PROTOCOL FOR MOBILE AD HOC NETWORKST. Peer Meera Labbai, V. RajamaniA mobile ad hoc network is a group of nodes which are communicating with each other with the use of radio frequencies. When there is high movement of mobile nodes, the nodes find difficult to reach other nodes. If the data are exchanged between nodes when there is high mobility, the data may be lost in transit. Therefore the security … …Journal of Computer Science, Vol. 9, Issue 10 · 5 Sep 2013 · 6,727 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhancing Security in E-Health Communications using Multi-Agent SystemRossilawati Sulaiman, Dharmendra Sharma, Wanli Ma, Dat TranProblem statement: In this study, we address the security needs in online communications, specifically in the e-health domain. We focus on how to provide different security strengths to different types of communications in e-health, where each communication transmits different types of information with different levels of sensitivity. Approach: The Multi-Agent System (MAS) approach is used to develop an agent-based system … …Journal of Computer Science, Vol. 8, Issue 5 · 17 Feb 2012 · 6,981 accessesView PDFCite
