| Abstract | Searchable encrypted log provides a facility to disclose only records which match some specified conditions. However, searching on an encrypted log takes a long time because checking for the condition usually requires a vast number of public key operations. In the field of plain text search, inverted index is a typical data structure to improve the performance of search speed which turns a bunch of comparison into a simple table lookup. This paper introduces an encrypted version of inverted index which can be used for a searchable encrypted log. Encrypted inverted index enables to determine all records that contain a keyword while contents of other records are kept secret. Statistic information such as frequency of each word is also not revealed. A prototype system is implemented to show the efficiency |

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.
