International audienceNumerical methods are necessary to understand the behav- iors of complex hybrid systems used to design control-command systems. Especially, numerical integration methods are heavily used in simulation to compute approximations of the solution of differential equations, in- cluding non-linear and stiff solutions. Nevertheless, these methods only produce approximate results and they should not be used in formal ver- ification methods as is. We propose a systematic way to make explicit Runge-Kutta integration method safe with respect to the mathemati- cal solution. As side effect, we can hence compare different integration schemes in order to pick the right one in different situations
This article presents the open source BINSEC platform for (formal) binary-level code analysis. The platform is based on an extension of the DBA Intermediate Representation, and it is composed of three main modules: a front-end including several syntactic disassembly algorithms and heavy simplification of the resulting IR, a simulator supporting the recent low-level region-based memory model, and a generic static analysis module. 2 Intermediate Representation: Extended DBA DBA Model. Dynamic Bit-vector Automata (DBA) [5] have been proposed as a generic and concise formal model for low-level programs. They offer the following advantages: Work partially funded by French ANR (project BINSEC, grant ANR-12-INSE-0002).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
