The increasing popularity of cloud storage services has lead companies that handle critical data to think about using these services for their storage needs. To keep their sensitive data against untrusted cloud service providers, a natural way is to store only encrypted data in the cloud severs and providing an efficient access control mechanism.. The proposed model involves the attributes of metadata for key generation and distribution techniques. The key problems of this approach includes, the generation of cipher key and establishing an access control mechanism for the encrypted data using cipher key, where keys cannot be revoked without the involvement of user, metadata data server (MDS) and Data Server (DS). From this study, we propose a novel metadata driven cipher key generation and distribution policies by means of exploiting the characteristic of the metadata stored called CRE Scheme, a Cloud Re-Encryption model that improves the confidentiality of the data stored through the cipher-key Cmxn. We have implemented our security model using eucalyptus tool and evaluated the performance and scalability of the secured model. We observed that our protocols improved the security of the data stored and compared with existing security models.
