A timing attack exploits the variance in the running time of a crypto-algorithm's implementation in order to infer confidential information. Such a dependence between confidential information and the running time, called a timing channel, is often caused by branching of the control flow in the implementation's source code with branching conditions depending on the attacked secrets. We present the Side Channel Finder, a static analysis tool for detection of such timing channels in Java implementations of cryptographic algorithms.
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.
