Cloud expands their IT services in a wide range to increase their potentiality in worldwide; among them data outsourcing is one of the major functionality in cloud storage. Maintaining the security, privacy and effective way of data sharing becomes a critical job for cloud providers. To overcome this problem, the authors newly presented a symmetric key cryptographic approach which generates a constant size cipher text. An individual user can effectively decrypt the encrypted data from shared cloud. A compact key contains set of secret keys which is generated by the key distribution center on the basis of file and user's privileges who want to access the data from the cloud storages. They can able to store this compact key conveniently in limited stored space.
