A Lattice Model of Secure Information Flow

  title={A Lattice Model of Secure Information Flow},
  author={Dorothy E. Denning},
  journal={Commun. ACM},
This paper investigates mechanisms that guarantee secure information flow in a computer system. These mechanisms are examined within a mathematical framework suitable for formulating the requirements of secure information flow among security classes. The central component of the model is a lattice structure derived from the security classes and justified by the semantics of information flow. The lattice properties permit concise formulations of the security requirements of different existing… CONTINUE READING
