We present a mathematical framework for expressing trust management systems. The framework makes it easier to understand existing systems and to compare them to one another as well as to design new systems. The framework defines the semantics of a trust management engine via a least fixpoint in a lattice, which, in some situations, leads to an efficient implementation. To demonstrate its flexibility, we present KeyNote and SPKI as instantiations by the framework.
