Research on Access Control Model Based on User Trust Degree and Resource Life Cycle under Mobile Environment

摘要

Traditional role-based access control models cannot meet the changing requirements of the roles and users under the mobile Internet environment due to their static attributes. To address such issue, this paper proposes an access control model, which is based on the user trust degree and the resource life cycle. From the perspective of subject, the proposed model takes the trust degree's impact factor and the trust degree's fading factor into consideration. From the perspective of object, it takes life cycle of resources into consideration. By using factors given above together, the model accomplishes the function of switching constraints dynamically in the mobile environment. At last, this paper analyzes the main characteristics of the proposed model and other traditional models, the results of analysis show that the proposed access control model has more advantages than other models in the mobile environment.
