Cloud storage enables users to remotely store their data and enjoy the on demand high quality cloud applications without the burden of local hardware and software management. To achieve the assurances of cloud data integrity and availability and enforce the quality of dependable cloud storage service for users. This project proposed an effective Attribute based encryption with verifiable outsourced Decryption. Attribute Based Encryption is a standard encryption that allows users to encrypt and decrypt data based on user attributes. It is flexible access control of encrypted data stored in the cloud. It is using access polices and attributes associated with private keys. The drawbacks of this scheme are that decryption involves expensive pairing operations. It does not guarantee the correctness of the transformation done by the cloud. We consider a new requirement of ABE with outsourced decryption perform verifiability process. This verifiability used guarantees that a user can efficiently check if the transformation is done correctly. The main aim of this project is without relying on random oracles.
