Description: The dRBAC modelis a scalable，decentralized trust—management and access—control mechanism for systems that span
multiple administrative domains．The dRBAC model supports three feathers：third—party delegations，valued attributes，cre—
dential subscription．However，there are some limitations of the dRBAC model，which represent the following issues：no con—
troI on the depth of delegation，circular search for delegation chain，covert promotion of role，violating separation of duty． In
this paper，these issues are discussed in detail，and reasonable resolutions of these issues are proposed in order to improve the
security and practicability of the dRBAC model．
