摘　　要：基于一个拥有多个子网且它们的密级不同的网络，该网络的信息是从低密级子网流向高密级子网，通过引入将子网密级、客体密级和客体的完整性等级相结合的三维安全函数新概念，通过扩充客体和主体，构造出了一个新的安全信息流模型，该模型能较好地反映网络的安全要求。A new secure information flow model based on the network of multi-classifications is de- scribed. In the network, there are more sub-network which has different classifications , information flow from the sub-network of the lower classifications to upper＇s, and in the model , the new concept of the three dimensions safe function is used, which joined with the classifications of the sub-network, the classi-fications and the degree of integrality of the object, and the object and subject are expended. The safe request of the network will be satisfied better in the model.
