Research on hiberarchy trusted network based on the grade division

A framework of hiberarchy trusted network based on the grade division was put forward, and the partition rules of trusted attributes as well as the methods of grade division were explained in detail. Moreover, the potential applications of this framework in trusted network were discussed, and the access procedure of terminals in hiberarchy trusted network was given based on the existing research results. Simulations show that by the proposed framework, not only the safety and reliability of network can be ensured, but also the flexibility of ways to access network is strengthened, and that the framework can provide supports for interoperability of different equipment suppliers.
