Using cloud storage, users can remotely store their data and enjoy the on-demand high-quality applications and services from a shared pool of configurable computing resources, without the burden of local data storage and maintenance. However, the fact that users no longer have physical possession of the outsourced data makes the data integrity protection in cloud computing formidable task, especially for users with constrained computing resources. Moreover, users should be able to just use the cloud storage as if it is local, without worrying about the need to verify its integrity. This paper enables security in cloud using encryption key that is generated while uploaded files by the user. The random key is generated using random key generation algorithm. The user can transfer their files with the permission of the owner. Multi-keyword ranked search over encrypted cloud data establish a set of strict privacy requirements for such a secure cloud data utilization system to become a reality. This provides high security while sharing files in cloud. The user can audit their uploaded files and verify the contents of the uploaded file in the cloud.
