Abstract: Cloud computing is considered nowadays as the only solution to increasing newlinestorage costs of IT enterprises. The costs of data storage device are very high and newlinewith huge quantity of data being generated every minute, it becomes very costly for newlineorganizations to upgrade their hardware regularly. Only outsourcing the data to newlinecloud helps in solving the problem. Storing the data in cloud results in moving newlineuser s data to remotely located data centres and user have no control over his own newlinedata. This creates many challenging security and privacy issues which must be newlineaddressed. A way to diminish these is to encrypt the data in client side itself. newlineSometimes, data owner will be overburdened with high computation and newlinecommunication costs, if he has to do the whole encryption and send it to cloud. newlineHence to reduce the burden of data owners, dual encryption is performed with newlinecoarse encryption in data owner side and a fine encryption in cloud side. Here access newlinecontrol policies must be properly decomposed to enable dual encryption process. In newlinethe proposed system, users enter and exit the cloud, without any central authority or newlinegroup manager. The proposed system ensures privacy preservation of users, data newlineconfidentiality and integrity in the cloud while delegating most of the access control newlineenforcement to the cloud. The data integrity algorithm proposed gives data integrity newlinein the cloud when downloading the data itself, which takes more time. newline
