“…This is even more accentuated with resource limited applications such as embedded systems. Recently, in Lounas et al (2017a), the authors pointed out the difficulty to embed formal verification for semantical correctness in a DSU system for Java Card applications.…”

Dymanic software updating (DSU) consists in updating running programs on-the-fly without any downtime that leads to systems unavailability. The use of DSU in critical applications raises several issues related to update correctness. Indeed, an erroneous dynamic update may introduce safety vulnerabilities and security breaches. In this perspective, the use of formal methods has gained a large interest since they respond to the high need of rigor required by such applications. Several frameworks were developed to first express update correctness which is based on several criteria. Then, the proposed formalisms are used to specify DSU systems, express correctness criteria and establish them. In this paper, we present a review of researches on the application of formal methods to DSU systems. We give a classification of systems according to the paradigms of programming languages and then we explain the correctness criteria and categorise the articles regarding the approaches of formalisation to establish the correctness. This information is useful to help ongoing researches in having an overview on the application of formal methods in DSU.

“…Semantics-based formalization is promising in providing effective and practical solutions for guaranteeing the correctness of dynamic software updating. For instance, Lounas et al achieved formal verification of dynamic updating of Java programs based on Java's semantics [7]. Compared with their approach, our approach is more general and extendable as K provides an elegant semantic framework for the definition of programming languages and an easy-to-use automated verification tool generation service.…”

Dynamic Software Updating (DSU) is a useful technique for updating running software without incurring any downtime. Its correctness must be guaranteed because updating a running software is a complicated and safety-critical process. In this paper, we present a formal tool called KupC for modeling and verifying dynamic updating of C programs. The tool is built on K-a formal semantic framework for programming languages. We formalize a patch-based dynamic updating mechanism in K based on the formal executable operational semantics of C. The formalization automatically yields an interpreter and several verification tools, which can be used to formally analyze the correctness of dynamic updating for C programs. To our knowledge, KupC is the first formal tool for code-level verification of dynamic software updating.
