Research ArticleOpen accessIn the abstractA Fragile Watermarking Scheme for Image Authentication with Tamper Localization Using Integer Wavelet TransformP. MeenakshiDevi, M. Venkatesan, K. DuraiswamyProblem statement: In recent years, as digital media are gaining wider popularity, their security related issues are becoming greater concern. Method for authenticating and assuring the integrity of the image is required. Image authentication is possible by embedding a layer of the authentication signature into the digital image using a digital watermark. In some applications tamper localization is also required. … …Journal of Computer Science, Vol. 5, Issue 11 · 30 Nov 2009 · 7,734 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Approach for Detecting Attacks in Mobile Adhoc NetworksV. Madhu Viswanatham, A. A. ChariThe security of data becomes more important with the increased use of commercial applications over wireless network environments. We presented an approach to handle various attacks for wireless networks. There were several problems of security in wireless networks due to intruders and different type of attacks such as Node Isolation, Route Disruption and Resource Consumption. There were better methods and … …Journal of Computer Science, Vol. 4, Issue 3 · 31 Mar 2008 · 6,928 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Secure Protocol Based on a Sedentary Agent for Mobile Agent EnvironmentsAbdelmorhit E. Rhazi, Samuel Pierre, Hanifa BouchenebThe main challenge when deploying mobile agent environments pertains to security issues concerning mobile agents and their executive platform. This paper proposes a secure protocol which protects mobile agents against attacks from malicious hosts in these environments. Protection is based on the perfect cooperation of a sedentary agent running inside a trusted third host. Results show that the protocol detects … …Journal of Computer Science, Vol. 3, Issue 1 · 31 Jan 2007 · 6,881 accessesView PDFCite
Review ArticleOpen accessIn the abstractMeta-Analysis of Data Collect MethodsIman Tikito, Mohammed El Arass, Nissrine SouissiSeveral organizations from different sectors depend increasingly on knowledge extracted from huge volumes of data generated by different sources, such as IoT, sensors and databases. At the core of data lifecycle, data reliability, analytics, security, scalability and use are important concerns. Coping with these issues in handling data requires understanding the challenges associated with it. Analysis process and storage devices … …Journal of Computer Science, Vol. 15, Issue 8 · 24 Aug 2019 · 7,339 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Survey of Anomaly Detection Using Data Mining Methods for Hypertext Transfer Protocol Web ServicesMohsen Kakavand, Norwati Mustapha, Aida Mustapha et al.In contrast to traditional Intrusion Detection Systems (IDSs), data mining anomaly detection methods/techniques has been widely used in the domain of network traffic data for intrusion detection and cyber threat. Data mining is widely recognized as popular and important intelligent and automatic tools to assist humans in big data security analysis and anomaly detection over IDSs. In this study we … …Journal of Computer Science, Vol. 11, Issue 1 · 22 Jan 2015 · 9,256 accessesView PDFCite
Research ArticleOpen accessIn the abstractCOMPARATIVE STUDY OF DIFFERENT KALMAN FILTER IMPLEMENTATIONS IN POWER SYSTEM STABILITYH. H. Goh, C. W. Tai, Q. S. Chua et al.Voltage stability and voltage collapse issues have in recent years begun to constitute an unpleasant warning to the operational security of power systems. Many techniques have been investigated in order to predict the point of voltage collapse. However, there are still several restrictions due to the insufficiency of current system state information. Accompanied by the commencement of the Phasor Measurement … …American Journal of Applied Sciences, Vol. 11, Issue 8 · 29 May 2014 · 7,197 accessesView PDFCite
Research ArticleOpen accessIn the abstractEFFICIENT KEY MANAGEMENT AND AUTHENTICATION SCHEME FOR WIRELESS SENSOR NETWORKST. Lalitha, R. Saravana Kumar, R. HamsaveniWireless Sensor Networks (WSN) is vulnerable to node capture attacks in which an attacker can capture one or more sensor nodes and reveal all stored security information which enables him to compromise a part of the WSN communications. Due to large number of sensor nodes and lack of information about deployment and hardware capabilities of sensor node, key management in … …American Journal of Applied Sciences, Vol. 11, Issue 6 · 10 Apr 2014 · 6,987 accessesView PDFCite
Research ArticleOpen accessIn the abstractIMPROVING FAULT TOLERANT RESOURCE OPTIMIZED AWARE JOB SCHEDULING FOR GRID COMPUTINGK. Nirmala Devi, A. TamilarasiWorkflow brokers of existing Grid Scheduling Systems are lack of cooperation mechanism which causes inefficient schedules of application distributed resources and it also worsens the utilization of various resources including network bandwidth and computational cycles. Furthermore considering the literature, all of these existing brokering systems primarily evolved around models of centralized hierarchical or client/server. In such models, vital responsibility such … …Journal of Computer Science, Vol. 10, Issue 5 · 4 Jan 2014 · 6,904 accessesView PDFCite
Research ArticleOpen accessIn the abstractSECRET HANDSHAKE ISSUE AND VALIDATE AUTHORITY BASED AUTHENTICATION SYSTEM FOR WIRELESS SENSOR NETWORKKamalanaban Ethala, R. Seshadri, N. G. Renganathan, M. S. SaravananWireless Sensor Networks (WSN) are major research area in the past few decades. WSN is formed by collection of sensor nodes. Power source life and memory size limit the hardware sources and these will decide the lifesapn of sensor nodes in WSN. Therefore, many resources based research issues are evolved in WSN. This study focused security issue and proposed authentication … …Journal of Computer Science, Vol. 9, Issue 9 · 6 Aug 2013 · 6,433 accessesView PDFCite
