Efficient Multi-keyword Ranked Search For Multiple Data Owner In Cloud Computing By Using AES 3DES Hybrid Approach

Abstract

With the rapid development of various multimedia technologies, more and more multimedia data are generated
and transmitted in the medical, also the internet allows for wide distribution of digital media data. It becomes much easier to
edit, modify and duplicate digital information .Besides that, digital documents are also easy to copy and distribute, therefore
it will be faced by many threats. Privacy preserving Ranked Multi-keyword Search in a Multi-owner model (PRMSM). To
enable cloud servers to perform secure search without knowing the actual data of both keywords and trapdoors, in this
proposed system systematically construct a novel secure search protocol. To rank the search results and preserve the privacy
of relevance scores between keywords and files, we propose a novel Additive Order and Privacy Preserving Function family.
To prevent the attackers from eavesdropping secret keys and pretending to be legal data users submitting searches, we
propose a novel dynamic secret key generation protocol and a new data user authentication protocol. Furthermore, PRMSM
supports efficient data user revocation. Extensive experiments on real-world datasets confirm the efficacy and efficiency of
PRMSM.
