Abstract: Based on the actual demands of cloud storage system, a new multi-authority ABE (MA-ABE) scheme is constructed to support user privacy protection and attribute revocation. For enhancing efficiency and alleviatingowner’s computing load, the complex computing works involved in attribute revocation are delegated to a trusted third party orcloud server. The proposed scheme is provably secure under the DBDH assumption.
