| Abstract: | We propose an algorithm which combines parameterized constraints and trust worthiness. Simulation results show that the algorithm can effectively shield the requests from the undesirable entities, achieving the fine grit authorization in a rather flexible way. Simultaneously, this algorithm enhances the computing efficiency and reduces the space for building the credential chains. |
