Abstract:There exists a problem of user privacy leakage in the smart grids (SGs) that malicious attackers may intercept or tamper with electricity data and associate the stolen data with real users to commit crimes. Besides, node equipment resources in the SGs are limited. Aiming at the problems above, most of the existing privacy-preserving schemes apply aggregate signature to ensure the integrity of message and improve communication efficiency. However, they cannot realize the anonymity of users to block link attacks… 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.
