Now-a-days as cloud is most widely used in mostly all fields so there is need of keeping data more secure & confidential which is outsourced on the cloud. As the cloud system is decentralized and distributed, any unauthorized user can access this data so to avoid this we need secure access control. In this system the access control is attribute based and ciphertext is used which is better scheme. This system provides hierarchical control structure to reduce burden of central authority. Computation cost of encryption and decryption is less and the size of ciphertext generated is constant. This proposed scheme is efficient, fine-grained and scalable and also increases performance of the system.
