| Abstract | Several symmetric-key distribution mechanisms are proposed in the literature, but most of them are not scalable or they are vulnerable to a small number of captured nodes. In this paper, we propose a new dynamic random key establishment mechanism in large-scale distributed sensor networks, which supports deployment of sensor nodes in multiple phases. In the existing random key distribution schemes, nodes do not refresh their own keys, and thus, the keys in their key rings remain static throughout the lifetime of the network. One good property of our dynamic key distribution scheme is that the already deployed nodes in a deployment phase refresh their own keys in key rings before another deployment phase occurs. The strength of the proposed scheme is that it provides high resilience against node capture as compared to that for the other existing random key distribution schemes. Through analysis and simulation results, we show that our scheme achieves better network performances as compared to those for the existing random key distribution schemes. Finally, we propose an extended version of our scheme for practical usefulness to support high network connectivity and resilience against node capture. |

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.
