Comparing controlled system synthesis and suppression enforcement

Abstract

Runtime enforcement and control system synthesis are two verification techniques that automate the process of transforming an erroneous system into a valid one. As both techniques can modify the behaviour of a system to prevent erroneous executions, they are both ideal for ensuring safety. In this paper, we investigate the interplay between these two techniques and identify control system synthesis as being the static counterpart to suppression-based runtime enforcement, in the context of safety properties.
