Research ArticleOpen accessIn the abstractAn Effective Contributory Re-Keying Approach to Compute Conference KeyD. Thilagavathy, M. RajaramProblem statement: With the explosive growth of and internet and web applications many emerging group-oriented distributed applications such as tele/video-conferencing, multiplayer games are based on group communication model that need security services such as privacy and data integrity Hence a secure distributed group key agreement is required to establish and authenticate a common group key for secure and private communication. … …Journal of Computer Science, Vol. 7, Issue 8 · 15 Jul 2011 · 6,643 accessesView PDFCite
Research ArticleOpen accessIn the abstractEfficiency Analysis for Public Key Systems Based on Fractal FunctionsNadia M.G. AL-Saidi, Mohamad Rushdan Md. Said, Adil Mahmood AhmedProblem statement: In the last decade, dynamical systems were utilized to develop cryptosystems, which ushered the era of continuous value cryptography that transformed the practical region from finite field to real numbers. Approach: Taking the security threats and privacy issues into consideration, fractals functions were incorporated into public-key cryptosystem due to their complicated mathematical structure and deterministic nature that meet … …Journal of Computer Science, Vol. 7, Issue 4 · 4 Apr 2011 · 6,939 accessesView PDFCite
Research ArticleOpen accessIn the abstractSecurity Extensible Access Control Markup Language Policy Integration Based on Role-Based Access Control Model in Healthcare Collaborative EnvironmentsTeo Poh Kuang, Hamidah Ibrahim, Nur Izura Udzir, Fatimah SidiRecently research is focused on security policy integration and conflict reconciliation among various healthcare organizations. Problem statement: However, challenging security and privacy risk issues still arisen during sharing sensitive patient data in different large distributed organizations. Though eXtensible Access Control Markup Language (XACML) has a powerful capacity of expression, it does not support all the elements character of RBAC. Thus, … …American Journal of Economics and Business Administration, Vol. 3, Issue 1 · 26 Jan 2011 · 9,067 accessesView PDFCite
Research ArticleOpen accessIn the abstractInformation Hiding: A Generic ApproachRiad jabri, Boran Ibrahim, Hadi Al-ZoubiProblem statement: Privacy and security over communication channels are of primary concerns. Due to their complexity and diversity, there is a need for continuous improvements of the adopted solutions. In this study, we consider two of the adopted ones, namely, steganogrphy and cryptography and propose a new information hiding system. Approach: The proposed system was based on a generic approach … …Journal of Computer Science, Vol. 5, Issue 12 · 31 Dec 2009 · 6,833 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of MD5 Authentication on Routing Traffic for the Case of: EIGRP, RIPv2 and OSPFK. A. Al-Saud, H. M. Tahir, Moutaz Saleh et al.Problem Statement: With the free flow of routing data and the high availability of computer resources, possible threats to the networks can result in loss of privacy and in malicious use of information or resources that can eventually lead to large monetary losses. Approach: MD5 Authentication: Due to the major role that routing protocols play in computer network infrastructures, special … …Journal of Computer Science, Vol. 4, Issue 9 · 30 Sep 2008 · 7,204 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Effective Data Transformation Approach for Privacy Preserving ClusteringR. R. Rajalaxmi, A. M. NatarajanA new stream of research privacy preserving data mining emerged due to the recent advances in data mining, Internet and security technologies. Data sharing among organizations considered to be useful which offer mutual benefit for business growth. Preserving the privacy of shared data for clustering was considered as the most challenging problem. To overcome the problem, the data owner published … …Journal of Computer Science, Vol. 4, Issue 4 · 30 Apr 2008 · 7,112 accessesView PDFCite
Research ArticleOpen accessIn the abstractCustomized Privacy Preservation Using Unknowns to Stymie Unearthing Of Association RulesJ. Indumathi, G.V. UmaThe explosions of new data mining techniques has augmented privacy risks because now it is probable to powerfully coalesce and cross-examine massive data stores, accessible on the web, in the rummage around of earlier unidentified hidden patterns. Consecutively to make a overtly accessible system safe and sound, we must guarantee not only that private sensitive data have been trimmed out, … …Journal of Computer Science, Vol. 3, Issue 11 · 30 Nov 2007 · 7,117 accessesView PDFCite
