Performance Comparison of Hybrid Encryption-based Access Control Schemes in NDN

Abstract

The newly emerging technologies and applications primarily focus on content distribution over the Internet, and a current host-centric TCP/IP Internet architecture becomes infeasible to fulfill this demand. Named Data Networking (NDN) is one of the most promising Future Internet architecture that facilitates a content-centric communication model over TCP/IP architecture. NDN supports in-network caching as the main characteristic that provides efficient scalability and minimum latency of content retrieval. Each NDN router possesses a content store table to cache the contents and directly serve the same requests in the future. Content can be cached anywhere in the NDN network, and content security and confidentiality become vital to prevent content access by unauthorized consumers. A hybrid encryption-based access control scheme has been proposed to address content confidentiality concerns by applying symmetric and identity-based proxy re-encryption schemes in NDN. However, it still requires further implementation and evaluation analyses with related schemes to prove that it offers a lower computational overhead and faster content retrieval time while protecting content confidentiality in NDN architecture. This paper conducts an additional experimental study on the scheme and shows some evidence about the reduction of the computational and communication time.
