| Abstract | The DDoS attack is more vulnerable attack in the self structured and infra structure less MANET environment. The bot net based flooding attack is very cheap and easy to implement. Many detection and prevention mechanisms has been proposed to avoid DDoS attack. Here we have proposed the stochastic model of covariance matrix analysis in which the entropy difference has been computed by the frequency distribution of rule metrics against the threshold entropy periodically which in turn difference is highest can be controlled by reCAPTCHA controller to defend against DDoS attack. The prevention mechanism by trust evaluation using clustering methodology used to identify the attacker and reduce the cost of detection mechanism. The Aumann agreement theorem based trust re-evaluation is also proposed in order to reduce the false positive and negative probabilities, such that the accuracy of the system is enhanced. Finally the nodes identified as attacker by their trust values will be evicted and rekeying has been done. The experimental analysis in NS2 with CAIDA dataset shows true positive rate and detection rate is high in the proposed mechanism. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
