Named data networking (NDN) is a data-centric Internet architecture. Although some security mechanisms are introduced in NDN packets, security still is a significant problem. We propose a privacy-aware transmission scheme for NDN (PATS_NDN) based on homomorphism and proxy re-encryption. To resolve name privacy in PATS_NDN, a content consumer can subscribe an interested content by using a blinded alias of content, and a data source can publish the produced content by using a blinded name. The alias of a content can be got from a quadratic function. A blinding algorithm is used on a content name and alias. In addition, homomorphic and proxy re-encryption are used to achieve secure content transmission. It has been proved that only a legitimate user can publish and access content on a network in our novel scheme. Finally, we analyse security attributes of our scheme and make a simple comparison with other related schemes.
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.
