Abstract

Nowadays, Everything can be searched through the cloud space. Therefore, this article is also dealing with the cloud computing, where searching of information and preservation of privacy is key area of concern. Henceforth taking multi-keyword ranked search with dynamic updation as a dimension of information searching, have been selected it as a research area. Moreover the searching is restricted to single keyword only. Therefore, we have taken the concept of multi keyword ranked searching. One more thing is that efforts have not been made regarding dynamic updation (insertion and deletion etc. of documents) previously. To cover up the dynamic updation part the schemes BDMRS-CM (Basic Dynamic Multi-Keyword Ranked Search scheme in the Known Ciphertext Model) by using the secure kNN algorithm and the EDMRS-BM (Enhanced Dynamic Multi-Keyword Ranked Search scheme in the Known Background Model) were designed and their performance have been evaluated and analyzed.

Keywords

Abstract

In these days, required information can be searched through the cloud. Henceforth, this paper deals with the cloud computing, where information seeking and privacy preservation are the main area of emphasis. Therefore, keeping multi-keyword ranked search with dynamic updation as an area of data searching (information seeking), have been chosen here as a research dimension. One more thing is that the in most of the cases searching is bounded to unit keyword only. Hence, we have chosen the other dimension of searching which is multi keyword ranking search. Moreover, efforts have not been made in the area of dynamic updation earlier. Here dynamic updation caters the addition and deletion of documents dynamically. For covering the dynamic updation part the scheme SSEDU (searchable symmetric encryption with dynamic updation) has been designed and deployed. In this paper we have presented the efforts made for the performance evaluation of the said SSEDU scheme.
