Software Defined Networking is a recent kind of stratified technology facilitate network management such as initialization, modification and manage the system behavior in a flexible way using open interfaces. Separate control plane from data plane by reducing the impact of failure and enhance resilience in resource management. SDN can manage the upsurge in security by providing tighter control on the network. The main purpose of the proposed system suggests an approach that integrates the address translation mechanism for LAN along with the SDN controller firewall and remaps the IP address into another by overcoming the end to end IP traceability, delay in communication and additionally maintains reinforcement by conveyance of packets. Efficient in reviewing the packets by adding policy rules in the firewall and reduce the internal traffic results in the displacement of packets in a secured and faster manner. Moreover, with the help of centralized controller facilitates the optimization and configuration of network by customizing the controller.

K. Krishnakumar, Nicholas, N., and N.S. Nair, “Reliable Video over SDN Using RBFS-Prune in an Unstructured Campus Network”, International Journal of Pure and Applied Mathematics, vol. 119, pp. 699-707, 2018.[Abstract]


Video applications expect the network to choose the most reliable path in the network, hinged on the minimum bandwidth needed by the application and the maximum delay and jitter that the application can tolerate. The network also needs to provide better QoS for any request from its origin to its destination. This paper cites the following: First, it cites apropos benefits of using Reliable Video over SDN (RVSDN) in an unstructured campus network. Next, it cites the design of using Recursive Best First Search-prune algorithm in RVSDN and its implementation. Third, it suggests use of Recursive Best First Search (RBFS)-prune algorithm can reduce the usage of SDN controller memory over A*-prune algorithm. Key Words:RBFS-Prune, RVSDN, reliable video

D. P. Correya, Gopinath, D., and N.S. Nair, “Prevention of man-in-the-middle phishing attack using pair based authentication”, International Journal of Applied Engineering Research, vol. 10, pp. 2024-2028, 2015.[Abstract]


Phishing is an attempt by fraudulent to acquire sensitive information such as log in credentials, credit card details and so on. Now a days all businesses depends on online services for fast and easy transactions. Though online business is an advantage for all business organizations, it affects their security. It also paid the way to hike in phishing attacks. By using several simple techniques phishers can easily steal sensitive information for their benefits. Financial organizations adopt one time password tokens to counter password phishing attacks. This alone is not sufficient for better security. To counter the security of one time password tokens phishers now uses a simpler technology Man-in-the-Middle phishing attack. This paper focus on the security against Man-in-the-Middle attacks with the help of a pair based authentication in order to ensure that the user is communicating with the real server instead of a proxy and a PKI encrypted token which helps the server to verify that the secret pass obtained from One Time Password is sent by the same user who provides the initial authentication. © Research India Publications.

A. Vasudevan, N.S. Nair, Benny, A. S., Shabana, K. M., Shenoy, A., and Dutta, M., “KARSHIK: Agricultural information monitoring and reference based on wireless networks”, in ACWR 2011 - Proceedings of the International Conference on Wireless Technologies for Humanitarian Relief, Amritapuri, 2011, pp. 537-539.[Abstract]


Karshik is a small scale, service administering project. The objective of this project is to make vital statistics about crops pertaining to a certain topology, geographic location and climatic conditions available to farmers in India, so as to equip them with information for producing the better yields; The long term aim of this project is to ultimately make a region self sufficient in the crops that can be suitably grown. This eradicates the need to import or strain resources that are sparse or extensively exploited in the pursuit of growing crops that are are not suited to a certain topology. In this paper the KARSHIK system is described. After a section dedicated to the explanation of the particular need of implementation, the paper describes the system's realization in Kerala-India for the analysis of crops suiting a certain terrain. The paper concludes with an outlook on future applications of the presented system. More »»
