| Abstract: | The paper presents a new scheme for pervasive computing-oriented dynamic multilevel security access control. The elements, dynamic access control mechanism are discussed respectively, at last the paper bewrote the authorization al-gorithm. Compared to the existing authorization models, the scheme we brought forward can insure dynamic authoriza-tion, and provides high security for the access control as well. The scheme is more suitable for pervasive computing envi-ronment. |
