Security Analysis on Multi keyword Data Search in Cloud using Encryption Techniques

With the popularity in cloud computing security and data search from complex data system is considered as one of the major concern. Considering the large number of data users and documents in cloud it is necessary for the search service to allow multi keyword query and provide results based on similarity ranking to meet effective data retrieval. In this project we propose one to many order preserving encryption (OPE), for applications of searchable encryption, which flattens the distribution of the plain text to solve the problem of secured multi keyword search (SMS) over encrypted cloud data (ECD). The result shows that data can be retrieved faster by efficient multi keyword search from remotely stored encrypted data.
