| Abstract | A key feature of the Content Centric Networking (CCN) architecture is the requirement for each piece of content to be individually signed by its publisher. Thus, CCN should, in principle, be immune to distributing fake content. However, in practice, the network cannot easily detect and drop fake content as the trust context (i.e., the public keys that need to be trusted for verifying the content signature) is an application-dependent concept. CCN provides mechanisms for consumers to request a piece of content restricted by its signer's public key or the cryptographic digest of the content object to avoid receiving fake content. However, it does not provide any mechanisms to learn this critical information prior to requesting the content. In this paper, we introduce a scalable Key Resolution Service (KRS) that can securely store and serve security information (e.g., public key certificates of publishers) for a namespace in CCN. We implement KRS as a service for CCN in ndnSIM, a ns-3 module, and discuss and evaluate such a distributed service. We demonstrate the feasibility and scalability of our design via simulations driven by real-traffic traces. |

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.
