摘要：in cloud computing, clients usually outsource their data to the cloud storage servers to reduce the management costs. While those data may contain sensitive personal information, the cloud servers cannot be fully trusted in protecting them. Encryption is a promising way to protect the confidentiality of the outsourced data, but it also introduces much difficulty to performing effective searches over encrypted information. Most existing works do not support efficient searches with complex query conditions . In this paper, we propose new scheme to solve the problem searching data on cloud because on the cloud data is stored in encrypted format. When the data search easily provides and also provides sharing between users. Data security is biggest issue on cloud. At that time provide safe searching and sharing between trusted users. Using these search results, cloud server will send encrypted document to the end user and at the user end perform decryption of data and get to original data.
