Abstract—This paper studies the foundations of informationflow security for interactive programs. Previous research assumes that the environment is total, that is, it must alway...
Robert Rosen’s central theorem states that organisms are fundamentally different to machines, mainly because they are ‘‘closed with respect to effcient causation.’’ The p...
A calculus is presented for the stepwise refinement of abstract information flow architectures. We give a mathematical model for information flow components based on relations bet...
This work presents a proposal to diagnose distributed systems utilizing model-based diagnosis using distributed databases. In order to improve aspects as versatility, persistence,...
Complex applications in many areas, including scientific computations and business-related web services, are created from collections of components to form workflows. In many case...
