We report on the development and use of formal verification tools within Amazon Web
Services (AWS) to increase the security assurance of its cloud infrastructure and to help …

The Independent Configurable Architecture for Reliable Operations of Unmanned Systems
(ICAROUS) is a software architecture incorporating a set of algorithms to enable …

Contract-based design enriches a component model with properties structured in pairs of
assumptions and guarantees. These properties are expressed in term of the variables at the …

JKind is an open-source industrial model checker developed by Rockwell Collins and the
University of Minnesota. JKind uses multiple parallel engines to prove or falsify safety …

Abstract Model-based engineering tools are increasingly being used for system-level
development of safety-critical systems. Architectural and behavioral models provide …

Contract-based design is an emerging paradigm for the design of complex systems, where
each component is associated with a contract, ie, a clear description of the expected …

Cyber-physical systems require the construction and management of various models to
assure their correct, safe, and secure operation. These various models are necessary …

The development of contemporary systems is an extremely complex process. One approach
to modeling system behavior uses activity diagrams from Unified Modeling Language …

Formal verification provides mathematical guarantees that a software is correct. Design-level
verification tools ensure software specifications are correct, but they do not expose defects in …

Arguments about the safety, security, and correctness of a complex system are often made in
the form of an assurance case. An assurance case is a structured argument, often …
