| Abstract | Nowadays, networked embedded systems (NESs) are required to be reconfigurable in order to be customizable to different operating environments and/or adaptable to changes in operating environment. However, reconfigurability acts against security as it introduces new sources of vulnerability. In this paper, we propose a security architecture that integrates, enriches and extends a component-based middleware layer with abstractions and mechanisms for secure reconfiguration and secure communication. The architecture provides a secure communication service that enforces application-specific fine-grained security policy. Furthermore, in order to support secure reconfiguration at the middleware level, the architecture provides a basic mechanism for authenticated downloading from a remote source. Finally, the architecture provides a rekeying service that performs key distribution and revocation. The architecture provides the services as a collection of middleware components that an application developer can instantiate according to the application requirements and constraints. The security architecture extends the middleware by exploiting the decoupling and encapsulation capabilities provided by components. It follows that the architecture results itself reconfigurable and can span heterogeneous devices. The security architecture has been implemented for different platforms including low-end, resource-poor ones such as Tmote Sky sensor devices. |

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.
