Abstract | Authentication and access control are the two main aspects of the security of P2P. Due to the semi-trusted nature of P2P network, authentication plays an important role in identification of the network user, authenticity and integrity of information-sharing. In this paper, we analyze the current P2P network authentication technologies and their shortages from two aspects: the identity and the text contents. We make conclusions that the "decentralized, semi-credible and dynamic nature" of P2P makes the problems of certificate management and key escrow to be especially outstanding, so that the traditional public-key cryptosystems including PKI and ID-PKC are very difficult to be applied in the P2P networks. For this reason, this paper proposes a P2P authentication technology based on CL-PKC (certificateless public key cryptograph) and further points out the key issues need to be studied. |

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.
