Research ArticleOpen accessIn the abstractAn Improved Location aided Cluster Based Routing Protocol with Intrusion Detection System in Mobile Ad Hoc NetworksS. Mangai, A. TamilarasiProblem statement: Routing and security are the main challenges for ad hoc networks due to dynamic topology as well as resource constraints. A designed protocol must provide scalable routing with better security. Lack of any central coordination and shared wireless medium makes them more vulnerable to attacks than wired networks. And also resource constraints such as limited energy and size … …Journal of Computer Science, Vol. 7, Issue 4 · 4 Apr 2011 · 7,103 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Robust Byzantine Fault-Tolerant Replication Technique for Peer-to-Peer Content DistributionAyyasamy Sellappan, Sivanandam NatarajanProblem statement: In peer-to-peer networks, Byzantine fault tolerance refers to the capability of a system to tolerate Byzantine faults. It can be achieved by replicating the server and by ensuring all server replicas reach an agreement on the input despite Byzantine faulty replicas and clients. Since malicious attacks and software errors can cause faulty nodes to exhibit Byzantine behavior, Byzantine-fault-tolerant … …Journal of Computer Science, Vol. 7, Issue 2 · 25 Feb 2011 · 7,056 accessesView PDF Cite

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 PDF Cite

Research ArticleOpen accessIn the abstractA Novel Routing Technique against Packet Dropping Attack in Adhoc NetworksN. Bhalaji, Sinchan banerjee, A. ShanmugamProblem Statement: Mobile adhoc networks (MANETs) were extensively used in defense and rescue applications. The dynamic topology of MANETs allows nodes to join and leave the network at any point of time. This dynamic property of MANET has rendered it vulnerable to various security attacks. Many trust establishment methods were proposed to increase the security in MANET. In this paper … …Journal of Computer Science, Vol. 4, Issue 7 · 31 Jul 2008 · 6,582 accessesView PDF Cite

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 · 6,878 accessesView PDF Cite

Research ArticleOpen accessIn the abstractReliability Evaluation of Distributed Computer Systems Subject to Imperfect Coverage and Dependent Common-Cause FailuresLiudong Xing, Akhilesh ShresthaImperfect coverage (IPC) occurs when a malicious component failure causes extensive damage due to inadequate fault detection, fault location or fault recovery. Common-cause failures (CCF) are multiple dependent component failures within a system due to a shared root cause. Both imperfect coverage and common-cause failures can exist in distributed computer systems and can contribute significantly to the overall system unreliability. … …Journal of Computer Science, Vol. 2, Issue 6 · 28 Sep 2006 · 6,838 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOn Analysis and Design of the Enhanced Firewall for Intranet SecurityU. K. Singh, A. K. Ramani, N. S. ChaudhariIntranet often employ an Internet firewall to mitigate risks of system penetration, data theft, data destruction and other security breaches. Conventional Internet firewalls impose an overly simple inside vs. outside model of security that is incompatible with many business practices that require extending limited trust to external entities. Additionally, firewall security perimeters are somewhat weak: they provide no protection from … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,709 accessesView PDF Cite

Review ArticleOpen accessIn the abstractA Systematic Review of Adversarial Attacks: ML Techniques, Classification and CountermeasuresBhavesh Kumar Sharma, Sanatan Ratna, Rajiv KumarMachine Learning (ML) and Deep Learning (DL)-based technologies have made significant strides in areas such as computer vision, natural language processing, and autonomous systems. Yet they have been applied in high-stake applications, and have been found to be fragile through adversarial attacks-, maliciously crafted small distortions that fool models into making mistakes. From the pioneering work by Szegedy et al. … …Journal of Computer Science, Vol. 22, Issue 5 · 19 May 2026 · 1,497 accessesView PDF Cite
