%X Nowadays,policies in the policy information models proposed by various research groups are isolated and there are no mechanisms for policy cooperation,so the requirements about policy cooperation in policy based security management systems are hard to be satisfied.In this paper,requirements of policy cooperation in policy based secuirty management systems are analyzed,and then the deficiencies of policy information models proposed by different research groups are analyzed according to policy cooperation requirements.Based on these analyses,a label based policy cooper- ation mechanism is proposed,which is extension to the current various policy information models and can satisfy the re- quirements of policy cooperation in secuirty management systems.The experiment and conclusions are present at last.
