Abstract: In order to give attention to BLP model and Biba model in process of implementing multi-level security system, the lattice theory shaped in math of security model sensitivity labels sets is analyzed. A security theoretical model of sensitivity labels lattice is proposed, which can fuse these two models. The information confidentiality and integrity are labeled. By setting up new sensitivity labels lattice theoretical models, the theory basis is provided to information security research.

Key words: security model, lattice, sensitivity label, BLP model, Biba model

摘要： 为在实现多级安全系统过程中有效兼顾BLP模型与Biba模型，分析安全模型敏感标记集合在数学上形成的格理论，提出一种能够有效融合这些模型的敏感标记格安全理论模型，以同时标识信息机密性与完整性，通过构建新的敏感标记格理论模型，为信息安全模型研究提供一定的理论依据。
