Content Confidentiality in Named Data Networking

Abstract

In this paper we present the design of name based access control scheme which facilitates data confidentiality by applying end-to-end encryption to data published on NDN with flexible fine-grained access control, which allows to define an enforce access policies on published data. The scheme is based on ciphertext-policy attribute-based encryption (CP-ABE). We discuss the use of the scheme on the basis of two use-cases, and report overhead associated with it, based on our implementation.
