In our proposed scheme, the data owner outsources huge volume of data to a cloud storage provider and the end users request data to the data owner. The data owner encrypts the data before sending it to the cloud service provider and does over-encryption proposed by Vimercati et al. [4] to the outsourced encrypted data before sending it to the users. We incorporate an existing Elliptic Curve Cryptography (ECC) based key management scheme in user hierarchy proposed by Nikooghadam et al. [11] in our scheme which classifies users in security classes and efficiently helps to derive the secret keys of the lower order security classes. The cloud storage component of our scheme will not have to perform any extra work except storing data and this reduces the cost of the data owner as per pay-per-use pricing policy of the cloud service provider. Our scheme incurs low overhead for key generation as well as for its storage and the end users can use wireless mobile devices. The scheme is useful in owner-write-users-read applications and it is secured from the adversaries.
