| Abstract | The open nature of modern network applications is potentially an excellent support to cooperative work of all sorts, and at the same time a major source of security and privacy concerns. It is now commonly recognized that traditional authentication techniques do not scale to the new open scenarios, and are not suitable for the dynamic nature of virtual organizations. Research is focussing on more flexible trust management models that let two or more peers interact securely even if they have never interacted with each other before and have no previous knowledge about each other's properties and protection requirements. This situation occurs whenever a new virtual organization is created or extended. Trust management is based on electronic credentials, that constitute a flexible way of representing properties of individuals, groups and organizations. In principle, any entity can issue its own credentials, thereby signing some statements about some entities. Other peers may decide whether that entity can be trusted on those statements, in the framework of a specific task. Credentials are verifiable and un-forgeable, so it can be robustly checked whether a given statement has been actually signed (hence issued) by a specific peer. |

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.
