A Thorough Review of Security in Information‐Centric Networking

The rapid evolution of technology has revealed the limitations of host‐centric or IP address–based networks. To overcome these limitations, a new communication paradigm has emerged: the information‐centric networking (ICN), which focuses on content (data) regardless of its location in the network. This new vision of networking addresses issues such as security and address space limitations inherent in the traditional IP address‐centric paradigm. Unlike its predecessor, ICN is based on content naming rather than IP addresses. ICN offers advantages such as improved quality of service, reduced data delivery time, enhanced data availability, and strengthened security. However, with these benefits come new vulnerabilities, particularly in content naming and caching. It is, therefore, crucial to understand the attacks specific to ICN. In this study, we first present an overview of the two network paradigms and fundamental security concepts, then, examine the various attacks in the ICN paradigm. We propose a taxonomy of these attacks and outline future research directions to address emerging security challenges.
