Abstract: In cloud computing, most of the data owners keeps their sensitive data on cloud. With this lot of data files stored in the cloud server, it is important to provide keyword based search service to data user. Now in order to protect the data privacy, sensitive data is usually encrypted before sent to the cloud server, which makes the search technologies on plaintext unusable. The system preserves the high search efficiency inherited from the inverted index while lifting the one-time-only search .limitation of the previous solutions which simultaneously meets a set of strict privacy requirements. A major challenge exposed from the existing efforts is the difficulty to protect user’s query privacy so this challenge is faced and tried to remove in this scheme.
