| Abstract | Classical trust model for Peer to Peer networks calculates the global trust value by iteration of local trust value. Every transaction will cause iteration throughout the whole networks resulting in huge communication traffic and computational complexity. Collusion attack, sleeping attack, slander attack, and so on are also faced, which are caused by sparse transactions data and inaccurate computing results. To ensure the density of transaction data and the accuracy of computing results, the paper presents a novel Peer to Peer trust model based on theory of probability and statistics. The history records of transactions are used to figure out the trust value of every peer with the maximum likelihood estimation and hypothesis testing. Every peer trades with other peers with high credibility. Mathematical analysis and simulation show it can resist attacks of malicious peers and improve the successful download rate of the whole Peer to Peer system compared with classical model Eigentrust. |

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.
