摘　　要：为兼顾对多级别人员的静态和动态信任管理,根据异常的危险程度对信任值进行定义和划分,并根据用户的信任值动态变化情况定义信誉值,由此给出一种基于信任和信誉的全局网格信任模型。针对不同级别人员和不同异常情况的仿真结果显示,利用基于全局信任模型,可以对网格进行客观评价和动态监测,为网格的主动防御提供决策依据。In order to take account both of the static and dynamic trust management of multi-level personnel,the trust value is defined and classified on the basis of the degree of abnormal risk,and the reputation value is defined according to the dynamic change situation of user＇s trust value,thus a grid trust model based on global trust and reputation is given.Simulations on different levels of personnel in different abnormal situations show that,the grid can be evaluated objectively and dynamically based on the global trust model,which can provide decision-making basis for active defense of grid.
