A STUDY OF SECURITY AND STORAGE OF DATA IN CLOUD COMPUTING ENVIRONMENT

: In cloud environment, the cloud data security plays an essential role in order to properly handle and access the data on cloud storage server. The protection of cloud data from the unauthorized user is a challenging task due to the lack of user authentication and authorization in cloud. The keyword extraction is the easiest way to extract the required documents/files relevant to the searched keywords. Many researchers have been focused on the providing secured keyword search to access data stored on cloud storage by introducing security protocol, cryptography techniques include encryption and decryption algorithms.
