MULTI KEYWORD RANKED SEARCH OVER ENCRYPTED CLOUD DATA
International Journal of Advance Engineering and Research Development · 2016
with the initiation of cloud computing, data possessors are driven to contract out their Complex data management systems from local sites to the commercial community cloud for great suppleness and financial savings. But for defending data privacy, complex data have to be encrypted before outsourcing, which obsoletes traditional data use based on plaintext keyword search. Thus, enabling an encrypted cloud data search service is of supreme position. 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 significance to these keywords. Related works on searchable encryption focus on single keyword search or Boolean keyword search, and rarely sort the Search results. We describe and crack the stimulating problem of privacy-preserving multi-keyword ranked search over encrypted data in cloud computing (MRSE).
