| Abstract | Rekeying process plays an important role in secure large-scale Storage Area Network (SAN) applications. Software based Rekeying management could not completely prevent sensitive information leakage from theoretical and physical attacks. Traditional Rekeying process will suffer from decrypting the large data using the old key and encrypting it with the new key. In order to solve these problems, we proposed a FPGA based flexible and low-cost rekeying management to improve the security and reduce the processing time. In the proposed method, enveloping key is defined and added into the rekeying process to protect the real private key and the user's access key. During the rekeying process, the user's access key is substituted and send back to the user instead of real private key. In order to save the transformation time between the Policies Key Control (software) and key management (hardware), we proposed index extraction solution to shorten bit width of transformation from 256-bit to only 32-bit. Experimental results show that our proposed method only takes up 1.099 ms for rekeying process compared with the existing design with 3.91 ms execution time. |

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.
