Abstract
Though traditional authorization models can ensure the security of equipment, they don’t offer promise both for good quality of service and for strong system robustness. Therefore, this paper presents a semi-distributed authorization model which splits the single decision point into two roles: core-authorization decision point and sub-authorization decision point. In this model, several decision points can provide authorization service for one and the same equipment. The experimental results prove that this model can effectively reduce authorization service time and has some marked advantages on system robustness.
