With the popular use of service-oriented technologies, Database as a Service (DaaS) paradigm is becoming a more practical and useful model for those enterprises who can't afford the expensive DBMS products. However, access control management by the Database Service Provider (DSP) in this paradigm is challenged because the DSP may be untrusted for the delegated data contents.
