Description/Abstract

Program certification techniques formally show that programs satisfy certain safety policies. They rely on the correctness of the safety policy which has to be established externally. In this paper we investigate an approach to show the correctness of safety policies which are formulated as a set of Hoare-style inference rules on the source code level. We develop a framework which is generic with respect to safety policies and which allows us to establish that proving the safety of a program statically guarantees dynamic safety, i.e., that the program never violates the safety property during its execution. We demonstrate our framework by proving safety policies for memory access safety and memory read/write limitations to be sound and complete. Finally, we formulate a set of generic safety inference rules which serve as the blueprint for the implementation of a verification condition generator which can be parameterized with different safety policies, and identify conditions on appropriate safety policies.
