摘　　要：为了应用多级安全策略,阻止信息流向不受信任的目的地,将BLP模型完整性增强的安全策略扩展到多级安全网络中,基于信息流的强制访问控制机制提出一个应用于多级安全网络的安全策略模型。该模型主要为网络层和数据链路层数据流提供相应的安全策略,很好地保证网络中数据流的机密性和完整性。In order to apply multilevel security policies to prohibit the information flowing to untrusted destination, proposes a new security policy model to support the mandatory access control to information flow in multilevel security network. The model has expanded the security policies with enhanced integrality of BLP model into multilevel security network.The model provides security policies for data stream of network layer and data link layer. It is proved that the model has good confidentiality and integrality.
