| Abstract | With the rapid and profound changes in computing technology, distributed computing, as an important branch of it, is becoming increasingly important, and gradually shifts from academia to specific areas of application. Currently, extensive researches on cloud computing, grid computing, large-scale E-Commerce web sites are all manifestations of a distributed system. Participating entities in a distributed environment have dynamic variable characteristics in the lifetime, which make the reliable operation of the entity and the rational use of resources face a security risk. The paper, stuck to the dynamic characteristics of a distributed environment, has proposed an evaluation model of Dynamic Entity Trust Degree to solve these security issues in a dynamic distributed environment. Based on a few key concepts of the trust mechanism, we quantified and proposed a Synthesize Trust Degree Evaluating Model (STDEM) by using Direct Trust Degree, Indirect Trust Degree, Trust Weight, Trust Attenuation, and specifically quantified the evaluation parameters for every kind of trust degree, providing an assessment for the credibility of the nodes in the distributed system. Parameters of the STDEM model were analyzed through simulation experiments and the STDEM was applied to specific data distributed systems with the validity of the model verified. |

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.
