This project focuses on the data security and privacy challenges of being able to provide delegated authorization and access permissions for Cloud services. We are currently working to define novel access control models, develop new encryption algorithms that use those models, implement software prototypes for a variety of cloud applications, and provide a well-defined set of access control policies. This research delves into three thrusts – theoretic advances, policy support, and prototype system building.
