Abstract:This paper studies the advanced methodologies of differential cryptanalysis with a particular emphasis on higher-order differentials and higher-order differential-linear cryptanalysis, along with their application to the ChaCha stream cipher. The study focuses on the impact of higher-order differential cryptanalysis on different rounds of the ChaCha stream cipher and analyzes how the cipher resists higherorder differential cryptanalysis. Additionally, we apply higher-order differential-linear cryptanalysis to … Show more
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.
