Research and Implementation of Access-control Model of Military Information System
Yan Jiao · Acta Armamentarii · 2009
For the complexity of access control mechanism of military information system,the concepts of domain role,role time-limit control,role conditional inheritance,role level and group were introduced into the management based on the available access control model.And task classification,task fraction,task time-based control and task template in the task management were studied according to the access control tactics,thus improving the task-role-based access control model.Task and role are referred to the centre of access control tactics to embody the access control thought involved the combination of active and passive access-visit,and the coexistence of static and dynamic authorization.Then a task-role-based access control model(M-TRBAC) was build to meet the demand of military information system.The formalized definition and the static and dynamic model design of M-TRBAC were given.
