Attributes based encryption (ABE) can achieve flexible and scalable access control and gurantee the confidentiality of the data stored in the cloud. However, important issues such as efficient user revocation and fine-grained access control are not straightforward, which constrain the adoption of ABE in cloud storage systems. Our proposed scheme realizes fine-grained read and write access control simultaneously and integrity auditing. These goals are achieved by exploiting and uniquely combining techniques of attribute-based encryption (ABE), proxy re-encryption, lazy re-encryption, public key signature, and key rotation.
