Contract-based design is a promising methodology for taming the complexity of developing sophisticated systems. A formal contract distinguishes between assumptions, which are constraints that the designer of a component puts on the environments in which the component can be used safely, and guarantees, which are promises that the designer asks from the team that implements the component.
A theory of formal contracts can be formalized as an interface theory, which supports the composition and refinement of both assumptions and guarantees.
Although there is a rich landscape of contract-based design methods that address functional and extra-functional properties, we present the first interface theory that is designed for ensuring system-wide security properties.
Our framework provides a refinement relation and a composition operation that support both incremental design and independent
implementability. We develop our theory for both stateless and stateful interfaces.
We illustrate the applicability of our framework with an example inspired from the automotive domain.
