Abstract
In the cloud, to keep data confidential and to achieve access control, the data owners can use attribute-based encryption to encrypt data. At the time of encryption, the access policies are not flexible. To achieve the strongest form of access control, so for construction of circuit’s cipher text we are using circuit cipher text-policy attribute-based encryption in our work. We also propose Division and Replication of Data in the Cloud for Optimal Performance and Security (DROPS) which provides solution for performance and security problems. In this methodology, file is separated into fragments and then encrypted and replicated fragments data stored on the nodes in cloud storage. Each node can stores only one fragment of data file that gives surety that even in case of a successful attack attacker will not get meaningful information. Third Party Auditor will check integrity of stored data and replace the tempered data with original one.
