2018. Context-Sensitive Flow Graph and Projective Single Assignment Form for Resolving Context-Dependency of Binary Code. Proceedings of the 13th Workshop on Programming Languages and Analysis for Security. :48-53.
Program analysis on binary code is considered as difficult because one has to resolve destinations of indirect jumps. However, there is another difficulty of context-dependency that matters when one processes binary programs that are not compiler generated. In this paper, we propose a novel approach for tackling these difficulties and describe a way to reconstruct a control flow from a binary program with no extra assumptions than the operational meaning of machine instructions.
