Understanding Security and Privacy Characteristics ofHybrid-based IP-ICN Coexistence Architectures

Abstract

Information-centric Networking (ICN) is the revolution of the internet due to its many benefit over the current internet infrastructure, namely caching, location-independent routing, and data-centric security. ICN ensures seamless data transfer due to its content-centric nature. Due to its content-centric nature, it is a must to ensure that security and privacy are in place before a shift to ICN takes place. There are three ways to make a shift to ICN: 1) Underlay, deploying ICN under the IP; 2) Overlay, deploying ICN over IP; 3) Hybrid, deploying ICN with IP. In this paper, we center on hybrid ICN architectures, two architectures are analyzed to examine their security and privacy features. The two architectures discussed are Hybrid Information-Centric Networking (hICN), and Content Centric Inter-Networking (CONET). Background and related works, on ICN as a whole, and the two architectures are given, followed by the analysis of the two. Features namely Availability, Access Control, Non-repudiation, Integrity, and Authentication are studied under security. Whereas in privacy, Anonymity, Confidentiality, and Unlinkability are studied. The paper presents the implementation and the relevance of these features to ICN architecture. After analyzing these traits separately in the two architectures, a comparison is drawn between them. Lastly, the conclusions are formed with a discussion of future works.
