Li Wen · Computer Engineering and Applications Journal · 2011
On the basis of the BLP model and RBAC model,a new improved multiple-level model is presented.The improved model has four important features:(1)carry out the control of integrity;(2)constrain the trusted subject and limit the right of other subjects;(3)realize RBAC model to assign the role and the permission;(4)fulfill the audit mechanism rules to monitor the security policy.Experimental results show that the improved model increases security and the usability.
