| Abstract | Nowadays, there are more and more use of storage-provider through the Internet, such as Google and Hotmail e-mail accounts, which are convenient to store and transfer electronic files and medias. Though the storage-provider offers users the capability to collect, retrieve and search on the emails, however, there is no protection of the users' privacy. For example, it is unknown how to prevent some honest-but-curious storage-provider from learning the private information of the user, such as, searching criterion and access pattern, etc. In CRYPTO'07, Boneh et al. put forward a privacy-preserving solution to solve this open problem, under the public key infrastructure. They made use of PIR (private information retrieval) and several other techniques, which are theoretically interesting and likely to be the best approach in the underlying setting. In this paper, we investigate the practicality of the proposed scheme by Boneh et al. Surprisingly, our evaluation result shows that their proposal seems unlikely to be implementable with the latest technology, due to a large amount of computational cost involved. Note that it is the first time to analyze and examine the practicality of this public key encryption based keyword search protocol using PIR. |

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.
