A New Scheme for Pervasive Computing-Oriented Dynamic Multi-Level Security Access Control

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 algorithm.Compared to the existing authorization models, the scheme we brought forward can insure dynamic authorization, and provides high security for the access control as well.The scheme is more suitable for pervasive computing environment.
