Research ArticleOpen accessEvery word in the titlePro-Active Prevention of Clone Node Attacks in Wireless Sensor NetworksK. M. Anandkumar, C. JayakumarProblem statement: Wireless mobile sensor networks are deploying large, self-organized and adaptable sets of sensors for many applications such as military, environmental, health care, remote monitoring and other applications. Unfortunately, the simplicity and low-cost of these sensors make eases cloning of compromised nodes by attackers in the network. Due to the unattended nature of wireless sensor networks, an adversary can … …Journal of Computer Science, Vol. 8, Issue 10 · 28 Aug 2012 · 7,072 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Discrete Event Simulator for Extensive Defense Mechanism for Denial of Service Attacks AnalysisMaryam Tanha, Seyed Dawood Sajjadi Torshizi, S. ShamalaProblem statement: Seeking for defense mechanisms against low rate Denial of Service (DoS) attacks as a new generation of DoS attacks has received special attention during recent years. As a decisive factor, evaluating the performance of the offered mitigation techniques based on different metrics for determining the viability and ability of these countermeasures requires more research. Approach: The development of … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 21 Mar 2012 · 7,470 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffective Authentication Technique for Distributed Denial of Service Attacks in Wireless Local Area NetworksM. Moorthy, S. SathiyabamaProblem statement: In 802.11-based Wireless LAN (WLAN), there is an mproved risk of security attacks. To defeat concealed attacks, there is a necessity to authenticate both access points and wireless stations. Approach: We propose a defensive technique for DDoS attack in WLAN. This authentication technique includes an Authentication Server (AS) in addition to the Wireless Station (WS) and Access Point … …Journal of Computer Science, Vol. 8, Issue 6 · 14 Mar 2012 · 7,075 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDynamic Approach to Defend Against Distributed Denial of Service Attacks Using an Adaptive Spin Lock Rate Control MechanismR. Anurekha, K. Duraiswamy, A. Viswanathan et al.Problem statement: The last decade has seen many prominent Distributed Denial of Service (DDoS) attacks on high profile webservers. In this study, we deal with DDoS attacks by proposing a dynamic reactive defense system using an adaptive Spin Lock Rate control (D3SLR). D3SLR identifies malicious traffic flow towards a target system based on the volume of traffic flowing towards the … …Journal of Computer Science, Vol. 8, Issue 5 · 17 Feb 2012 · 7,062 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Effect of the Attacks of 9/11 on Organizational Policies, Employee Attitudes and Workers' Psychological StatesAmy E. Hurley-Hanson, Cristina M. Giannantonio, Heidi Carlos et al.Problem statement: The attacks of September 11, 2001 (9/11) on the United States have had a profound effect on organizations and their employees. These effects occurred in the days and weeks immediately following the attacks, as well as in the years since the attacks occurred. In commemoration of the tenth anniversary of 9/11, this study focuses on the impact that … …American Journal of Economics and Business Administration, Vol. 3, Issue 2 · 27 May 2011 · 8,282 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Combined Solution for Routing and Medium Access Control Layer Attacks in Mobile Ad Hoc NetworksR. Murugan, A. ShanmugamProblem statement: In Mobile Ad hoc Network (MANET), both the routing layer and the Medium Access Control (MAC) layer are vulnerable to several attacks. There are very few techniques to detect and isolate the attacks of both these layers simultaneously. In this study, we developed a combined solution for routing and MAC layer attacks. Approach: Our approach, makes use of … …Journal of Computer Science, Vol. 6, Issue 12 · 4 Nov 2010 · 7,135 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleQuantum Cryptography with Several Cloning AttacksMustapha Dehmani, Hamid Ez-Zahraouy, Abdelilah BenyoussefProblem statement: In a previous research, we investigated the quantum key distribution of the well known BB84 protocol with several intercept and resend attacks. In the present research, we studied the effect of many eavesdroppers cloning attacks of the Bennett-Brassard cryptographic protocol on the quantum error and mutual information between honest parties and information with sender for each eavesdropper. Approach: … …Journal of Computer Science, Vol. 6, Issue 7 · 31 Jul 2010 · 7,293 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMathematical Attacks on RSA CryptosystemImad K. Salah, Abdullah Darwish, Saleh OqeiliIn this paper some of the most common attacks against Rivest, Shamir, and Adleman (RSA) cryptosystem are presented. We describe the integer factoring attacks, attacks on the underlying mathematical function, as well as attacks that exploit details in implementations of the algorithm. Algorithms for each type of attacks are developed and analyzed by their complexity, memory requirements and area of … …Journal of Computer Science, Vol. 2, Issue 8 · 31 Aug 2006 · 8,420 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAn Optimized Multi-Layer Perceptron Framework for Detecting and Classifying IoT AttacksSanchit Vashisht, Shalli RaniThe Internet of Things (IoT) is revolutionizing industries by connecting billions of smart devices, enabling automation and information exchange. The expansion of IoT ecosystems has simultaneously increased the surface area for cyberattacks. These environments are particularly vulnerable to a wide range of threats, such as Distributed Denial-of-Service (DDoS), poisoning, brute-force SSH intrusions, and various network reconnaissance techniques. The dynamic nature … …Journal of Computer Science, Vol. 21, Issue 12 · 11 Feb 2026 · 1,333 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDEACT: Hardware Solution to Rowhammer AttacksTesfamichael Gebregziabher Gebrehiwot, Fitsum Assamnew Andargie, Mohammed IsmailDynamic Random Access Memory (DRAM) is a crucial component in modern computing devices. Improvements in process technology have significantly increased the speed and storage capacity of memory devices. However, as memory cells become smaller and closer to one another, annoying circuit disturbance errors such as the Row-hammer problem have become significant. Studies show that attackers can systematically exploit such errors … …Journal of Computer Science, Vol. 19, Issue 7 · 22 Jun 2023 · 6,483 accessesView PDFCite
