摘要：A novel approach for role mining in the context of role engineering for role-based access control is developed in this paper. We propose a simple algorithm, based on the assumption that permissions from the same role appear near each other in the access history log. Closely co- occurring groups of permissions are selected as candidate roles and are ranked based on a novel heuristic, called role cohesion, that quantizes the permission proximity of a candidate role in the access log. High-rank roles are identified using the algorithm, which is tested with a simulation scenario.
