Function of security kernel is to maintain security of information inside system.Security policy is implemented by using a module in security kernel usually by different security demand.RBAC is access control mechanism which can satisfy more security de-mand of system.But tradition RBAC can not easy change operate set of role,and would conflict with exterior application.Lack of tra-ditional RBAC can be got over by objecting operation of information,and dispatch them to application as role,and implemented object hierarchy model.
