Information-flow Interfaces

Abstract 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 designer component puts on environments in can be used safely, and guarantees promises asks from team implements component. theory contracts formalized as an interface supports composition refinement both guarantees. Although there rich landscape contract-based methods address functional extra-functional properties, we present first designed ensuring system-wide security properties. Our framework provides relation operation support incremental independent implementability. We develop our stateless stateful interfaces. illustrate applicability with example inspired automotive domain.
