| Abstract | Peer-to-Peer (P2P) content distribution becomes more and more popular because of dissemination of various high bit rate services such as high definition video streaming. To realize it with sufficient scalability, structured network is considered and actually adopted. In order to prevent a problem of thefts of content, P2P hybrid model is normally employed, which adopts a central server that manages authentication information of users. On the other hand, recently, pure P2P scheme is proposed to omit such a central server that causes the problem of single point of failure, and as a result, scalability can be increased. In the proposed scheme, (k, n) secret sharing scheme is employed to realize content key distribution among potentially unreliable P2P nodes. In this paper we propose a new content key management scheme that attains several important security requirements for dynamic content delivery such as forward secrecy, which did not realize in the previously proposed scheme. We also propose a design method of system parameters in a systematic manner for the proposed scheme by using Chernoff inequality. Finally, we evaluate a relation between the probability of successful recovery of content key for malicious nodes and the probability of content key recovery failure for legitimate nodes. |

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.
