Research ArticleOpen accessIn the abstractSecure Packet Encryption and Key Exchange System in Mobile Ad hoc NerworkSudhakar Sengan, S. Chenthur PandianProblem statement: Mobile Ad-hoc Network is infrastructureless network supported by no fixed trusted infrastructure. The packets had a chance to drop or hacked by eavesdropper during transmission. So, encryption method is required for sending and receiving packet in secret manner. Approach: In this approach, the block and key size had been increased by 256 bits. When compared to Rijndael algorithm, … …Journal of Computer Science, Vol. 8, Issue 6 · 17 Mar 2012 · 7,387 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnergy Constrained Secure Hierarchical Data Aggregation in Wireless Sensor NetworksV. Bhoopathy, R. M.S. ParvathiProblem statement: Wireless sensor networks, brings out variety of different challenges at energy level, integrity, authentication, communication cost. Approach: In the secure data aggregation techniques, reduction in the energy consumption was not elaborated in detail, since aggregator means of connection to sink was either direct or through other aggregators which need high energy level. Results: We suggest an Energy Constrained … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 16 Mar 2012 · 7,377 accessesView PDFCite
Research ArticleOpen accessIn the abstractMultimodal Biometrics using Feature FusionK. Krishneswari, S. ArumugamProblem statement: Biometric is a unique, measurable physiological or behavioral characteristic of a person and finds extensive applications in authentication and authorization. Fingerprint, palm print, iris, voice, are some of the most widely used biometric for personal identification. To reduce the error rates and enhance the usability of biometric system, multimodal biometric systems are used where more than one biometric … …Journal of Computer Science, Vol. 8, Issue 3 · 24 Jan 2012 · 7,370 accessesView PDFCite
Research ArticleOpen accessIn the abstractResearch of an Online Service System for Beverages Chain StoresChih-Yao Lo, Cheng-I Hou, Hsin-Chia Hsu, Chiu-Ping YouProblem statement: In the highly competitive market, the availability of consumer support is the key to market-based beverage stores. Consumer demands for quality service so the industry must be more active to improve the quality of management to ensure that beverage market position. In order to allow market competition to be improved for the beverage store. Approach: The system builds … …American Journal of Applied Sciences, Vol. 8, Issue 7 · 24 Jun 2011 · 7,051 accessesView PDFCite
Research ArticleOpen accessIn the abstractAuthenticated Broadcast in Heterogeneous Wireless Sensor Networks using Chinese Remainder Theorem AlgorithmKalyani Palanisamy, ChellappanProblem statement: The security in Wireless Sensor Networks (WSN) is a critical issue due to the inherent limitations of computational capacity, storage capacity and power usage. Key management only makes sure the communicating nodes possess the necessary keys, at the same time protecting the confidentiality, integrity and authenticity of the communicated data. Approach: Proposed a RSA-CRT methodology for authenticated broadcast … …Journal of Computer Science, Vol. 7, Issue 6 · 14 Jun 2011 · 6,413 accessesView PDFCite
Research ArticleOpen accessIn the abstractMobility Management for Seamless Information Flow in a Heterogeneous NetworksAdiline Macriga, AnandhakumarProblem statement: In the heterogeneous networks, generally the entire networks operating on the Radio Frequencies under wireless mode available for communication are brought under a single head based on their common operating procedures and functions. As a common mode the basic functions of the networks are requesting, tracing, sending, acknowledging, authenticating, authorizing, receiving, updating, forwarding, controlling, registering, managing. As the … …Journal of Computer Science, Vol. 7, Issue 2 · 25 Feb 2011 · 6,889 accessesView PDFCite
Research ArticleOpen accessIn the abstractMobile 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 PDFCite
Research ArticleOpen accessIn the abstractA 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 accessIn the abstractInvariant Image Watermarking Using Accurate Zernike MomentsIsmail A. Ismail, Mohamed A. Shouman, Khalid M. Hosny, Hayam M. Abdel SalamProblem statement: Digital image watermarking is the most popular method for image authentication, copyright protection and content description. Zernike moments are the most widely used moments in image processing and pattern recognition. The magnitudes of Zernike moments are rotation invariant so they can be used just as a watermark signal or be further modified to carry embedded data. The computed … …Journal of Computer Science, Vol. 6, Issue 1 · 31 Jul 2010 · 8,009 accessesView PDFCite
Research ArticleOpen accessIn the abstractOmega Network Hash ConstructionChai Wen Chuah, Azman SamsudinProblem statement: Cryptographic hash functions are important cryptographic primitives. They are commonly used for data integrity checking and data authentication. Most of the cryptographic hash functions are based on the Merkle-Damgård construction. The basic Merkle-Damgård construction runs over the input sequentially, which can lead to problems when the input size is large since the computation time increases linearly. Approach: Therefore, … …Journal of Computer Science, Vol. 5, Issue 12 · 31 Dec 2009 · 7,123 accessesView PDFCite
