To improve the efficiency of XACML rule matching by layer,in the rules optimization aspect,this paper proposed the thought of sorting of rules according to rules' request weight.At the same time,in the evaluation of policy aspect,this paper proposed the priorities of XACML combination algorithms and rules index table of the subject,preferentially select the satisfied policies and rules to improve the matching speed.The simulation experiment shows these measures shortened the evaluation time of PDP,improved the assessment efficiency.Finally,it proposed the future directions.
