Recent advances in cloud technology facilitates data owners having limited resources to outsource their and computations remote servers Cloud. To protect against unauthorized information access, sensitive are encrypted before outsourcing. However, traditional cryptosystems need decrypting ciphertext for outsourced that may violate security as well introduce higher computational complexity. Homomorphic encryption is a solution allows performing directly on ciphertext. On the otherhand, it evident vary from users depending requirements. So, not always feasible allow all different whole stored cloud. In this paper, we proposed framework integration of role based access control (RBAC) mechanism with homomorphic cryptosystem secure controlled Our developed trust hierarchy multi-granular operational rights heterogeneous stakeholders or users.
