Abstract :
In order to realize bilateral protocols, dynamic restriction of roles mutex and to solve the problems arose by permission sharing, a new model was proposed: role-based dynamic delegation model. Firstly, the main idea of the model was described. Secondly, the constituent elements, relationship of elements and delegation restrictions were expatiated with discrete mathematical expressions. Finally, details on how to achieve temporal delegation, part-role delegation, bilateral protocols, and dynamic restriction of roles mutex as well as how to solve the problem of permission sharing based on agent in the whole delegation process was described.
