In this paper, the features of access control in pervasive computing environment are summarized and the limitations of previous models are discussed. Then, a context-based and associated access control model is proposed, which integrates the principles of TBAC and RBAC and uses the environment context as a factor to reason role assigning and authority granting. The proposed model shows effectiveness in simplifying the procedures of access control and ensuring security. It also improves the flexibility and intelligence of access control, and those are the prerequisite of the transparency service. The structure of the proposed model and related definitions are described in this paper. Finally the design and implementation of the prototype system based on the model are also put forward.
