Access control is important to protect the network *** increasing demand for secure interactions between network domains brings in new challenges to access control *** this paper we design an access control model which provides a multilevel mapping method between hierarchical access control structures for achieving multilevel security protection in multi-domain networking *** access control structures ensure rigorous multilevel security in intra *** the mapping method based on quantized subject attributes is proposed to determine the subject's security level in its target *** is used in the model to adjust the mapping value in order to achieve flexible multilevel inter-domain access *** results we obtained from simulations are also reported in this paper to verify the effectiveness of the proposed access control model.
