Abstract: 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.

Keywords: content-centric networking; named data networking; homomorphic encryption; PRE; proxy re-encryption; privacy protection.
