title = "Implementing authorization delegations using graph",
abstract = "Graph-based approach to access control models have been studied by researchers due to its visualization, flexible representation and precise semantics. In this paper, we present a detailed graph-based algorithm to evaluate authorization delegations and resolve conflicts based on the shorter weighted path-take-precedence method. The approach makes it possible for administrators to control their granting of authorizations in a very flexible way. The correctness proof and time complexity of the algorithm are provided. We then consider how the authorization state can be changed, since in a dynamic environment an authorization state is not static. The detailed algorithm of state transformation and its correctness proof are also given.",
