| Abstract: | Delegation is a common form of a security policy. Delegation can be identified by a directed graph with its rigorous formal modeling, called the delegation graph. In this paper, the definition and the store of delegation graph are given, algorithm of how to implement delegation in the delegation graph and how to judge a directed acyclic graph is discussed. |
