摘要:
In this paper, we combine and generalize integrity and security lattices to a simpler flow model, demonstrate some common pitfalls in administration under this model, and show that the most general structure required for representing information flow in a general purpose transitive information network is a partial ordering. We show means for calculating information and time effects under this model, and show the design of a provably correct automated administrative assistant for protection administration in networks under this model.
