Paper Title
Privacy Preserving Multi-Keyword Ranked Search Over Encrypted Cloud Data

Abstract
With the advent of cloud computing, data owners are motivated to outsource their complex data management systems from local sites to the cloud for great flexibility and economic savings. But for protecting data privacy, sensitive data have to be encrypted before outsourcing, which obsoletes traditional data utilization based on plaintext keyword search. Thus, enabling an encrypted cloud data search service is of paramount importance. Considering the large number of data users and documents in the cloud, it is necessary to allow multiple keywords in the search request and return documents in the order of their relevance to these keywords. Related works on searchable encryption focus on single keyword search and rarely sort the search results. This paper defines and focuses on the problem of ranked search over encrypted data. It captures the relevance of data documents to the search query. Keywords— Cloud Computing, privacy, encryption, multiple keywords, ranked search.
