Research ArticleOpen accessIn the abstractPerformance Evaluation of Multicrypt Encryption MechanismRhymend Uthariaraj Vaidyanathan, Lydia Elizabeth Benjamin, John Prakash ArockiasamyMulticast communication allows a single message packet to be routed to multiple nodes simultaneously. Membership in a multicast group is dynamic, allowing nodes to enter and leave the multicast session. Besides the benefits, multicast communication presents the challenge of securing the communication. In order to preserve confidentiality the general encryption mechanism used for point to point communications are used. A … …American Journal of Applied Sciences, Vol. 9, Issue 11 · 4 Sep 2012 · 7,174 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluating the Strengths and Weaknesses of Mining Audit Data for Automated Models for Intrusion Detection in Tcpdump and Basic Security Module DataG. Mohammed Nazer, A. Arul Lawrence SelvakumarProblem statement: Intrusion Detection System (IDS) have become an important component of infrastructure protection mechanism to secure the current and emerging networks, its services and applications by detecting, alerting and taking necessary actions against the malicious activities. The network size, technology diversities and security policies make networks more challenging and hence there is a requirement for IDS which should be … …Journal of Computer Science, Vol. 8, Issue 10 · 25 Aug 2012 · 7,132 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Policy Based Scheme for Combined Data Security in Mobile Ad hoc NetworksL. Kartheesn, S. K. SrivatsaProblem statement: In Mobile Ad hoc Networks (MANET) routing protocols, we require a network-level or link layer security. Since without appropriate security provisions, the MANETs is subjected to attacks like network traffic, replay transmissions, manipulate packet headers and redirect routing messages. In order to address these needs, a policy based network management system that provides the capability to express network … …Journal of Computer Science, Vol. 8, Issue 8 · 6 Aug 2012 · 6,725 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Security Model using Multilayer Approach for E-Health ServicesRossilawati Sulaiman, Dharmendra Sharma, Wanli Ma, Dat TranProblem statement: Delivering services online is important in e-health. Services that are delivered through online communications between engaging parties, often involve sensitive information transmitted over the Internet. However, while the Internet successfully facilitates these services, significant threats also come in parallel. Network attacks, information breaches and malicious software on a computer system are common threats to the Internet. These threats … …Journal of Computer Science, Vol. 7, Issue 11 · 29 Aug 2011 · 6,825 accessesView PDFCite
Research ArticleOpen accessIn the abstractUbiquitous Health Monitoring Systems: Addressing Security ConcernsMahmoud Elkhodr, Seyed Shahrestani, Hon CheungProblem statement: It is important to secure the transmission of patient’s EHR in remote health monitoring systems. Security is among the main issues that need to be realized for the adaption of this monitoring technology. The face of healthcare is changing as ubiquitous computing technologies are being incorporated into the existing infrastructure. We specify the requirements, needed security mechanism, outstanding … …Journal of Computer Science, Vol. 7, Issue 10 · 4 Aug 2011 · 7,411 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Secure Routing Protocol to Eliminate Integrity, Authentication and Sleep Deprivation Based Threats in Mobile Ad hoc NetworkEdna Elizabeth Nallathambi, Radha Sankararajan, Vaithiyanathan Sundaram, Gracelin SheebaProblem statement: Network security in Mobile Ad hoc Network (MANET) is a major issue. Some of the attacks such as modification, impersonation, Time To Live (TTL) and sleep deprivation are due to misbehaviour of malicious nodes, which disrupts the transmission. Some of the existing security protocols such as ARAN, SAODV and SEAD are basically used to detect and eliminate one … …Journal of Computer Science, Vol. 7, Issue 6 · 14 Jun 2011 · 6,822 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 · 9,072 accessesView PDFCite
