Content Confidentiality in Named Data Networking

TL;DR

This paper proposes a name-based access control scheme for Named Data Networking that ensures data confidentiality through end-to-end encryption using ciphertext-policy attribute-based encryption, with practical implementation and overhead analysis.

Contribution

It introduces a novel name-based access control scheme for NDN utilizing CP-ABE for fine-grained data confidentiality and policy enforcement.

Findings

Implemented the scheme and evaluated overhead.

Demonstrated flexible fine-grained access control.

Validated applicability through use-case analysis.

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.
