Research ArticleOpen accessAll words, across the recordSECURE WIRELESS AD HOC NETWORKS USING ZERO KNOWLEDGE PROOFBenfano Soewito, Yonathan Marcellinus, Manik HapsaraA Mobile Ad-hoc Network (MANET) is a group of wireless mobile nodes that dynamically form a network without any pre-established infrastructure or centralized administration, Soewito (2014). Some network hops may be needed to send a packet from one node to another node in the MANET. To do the communication between the nodes, a route has to be selected in the … …Journal of Computer Science, Vol. 10, Issue 12 · 26 Dec 2014 · 7,863 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordCombating Cyber Terrorism-Assessment of Log for Malicious SignaturesKamalanaban Ethala, R. SeshadriEnhancing security to the networks and preventing the cyber attacks is a major issue in all domains. In this study, a new class of cyber terrorism is addressed where mischievous and malicious behaviour is the root cause for the modification of network data stored in an open database. An attempt is made in this study to develop an algorithm that … …American Journal of Applied Sciences, Vol. 10, Issue 12 · 7 Nov 2013 · 6,635 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordTemporal, Delegable and Cheap Update Access Control to Published XML DocumentsWaleed Halboob, Ali Mamat, Ramlan Mahmod, Muhammad Khurram KhanProviding access control for published XML documents on the Web is an important topic. It involves the use of cryptographic techniques, addressing different requirements and, as a result, facing several challenges. Existing solutions still have some weaknesses such as system update cost, number of required secret encryption/decryption keys, size of encrypted document and supporting temporal and delegable access. This study … …Journal of Computer Science, Vol. 9, Issue 4 · 8 May 2013 · 6,532 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordReconfigurable Hardware Architecture for Network Intrusion Detection SystemA. Kaleel Rahuman, G. AthishaIntrusion rule processing in reconfigurable hardware enables intrusion detection and prevention. The use of reconfigurable hardware for network security applications has great strides as Field Programmable Gate Array (FPGA) devices have provided larger and faster resources. This proposes architecture called “BV-TCAM” is presented, which is implemented for an FPGA-based Network Intrusion Detection Systems (NIDS). The BV-TCAM architecture combines the Ternary … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 16 Aug 2012 · 6,981 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordEffective 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 PDF Cite

Research ArticleOpen accessAll words, across the recordWheat Production and EconomicsElgilany Ahmed, Jamalludin Sulaiman, Saidatulakmal MohdProblem statement: The crop in the irrigated scheme has faced by manifold problems contributed to low level of productivity and high cost of production of wheat. The crop is commonly produced under pump irrigation from the River Nile. In River Nile State (RNS), wheat is grown under the irrigated sector, the State is considered as a suitable environment for producing … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 3 · 4 Aug 2011 · 10,569 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordAcknowledgment based Reputation Mechanism to Mitigate the Node Misbehavior in Mobile Ad Hoc NetworksK. Gopalakrishnan, V. Rhymend UthariarajProblem statement: The cooperation between the nodes is essential to discover and maintain routes in mobile ad hoc network. Due to the presence of misbehaving nodes, the node cooperation is not always guaranteed as the nodes agreed during the route discovery phase. This phenomenon results in frequent network partitioning and it makes the routing process difficult. It also degrades the … …Journal of Computer Science, Vol. 7, Issue 8 · 14 Jul 2011 · 6,567 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordMobile Ad Hoc Network Security for Reactive Routing Protocol with Node Reputation SchemeA. Suresh, Dr. K. DuraiswamyThe mobile node’s reputation in the Mobile Ad hoc Network (MANET) identifies its trust worthiness for secured multiple data communication. Unknown nature of the node’s communication status for initial period has great impact in the effective data transfer as MANET is self-organized and distributed. Problem statement: The functional operation of the mobile network relies on the trusty cooperation between the … …Journal of Computer Science, Vol. 7, Issue 2 · 25 Feb 2011 · 6,988 accessesView PDF Cite
