Abstract

The aim of the work is to demonstrate the key role of lattice theory as a mathematical foundation for building access rights delimitation systems. The construction of a lattice of security classes based on Denning's axioms and Hasse diagrams is considered, and how a clear hierarchy of access levels and categories of secrecy is built using lattices. The use of lattices is also shown using the example of the Bell-LaPadula model.
