Abstract

Information Centric Networking (ICN) is a new communication paradigm for the upcoming Next Generation Internet (NGI). ICN is an open environment that depends on in-network caching and focuses on contents rather than infrastructures or end-points as in current Internet architectures. These ICN attributes make ICN architectures subject to different types of routing and caching attacks. An attacker sends malicious requests that can cause Distributed Denial of Service (DDoS), cache pollution, and privacy violation of ICN architectures. In this paper, we propose a solution that detects and prevents these malicious requests in ICN routing and caching. This solution allows ICN routers to differentiate between legitimate and attack behaviours in the detection phase based on threshold values. In the prevention phase, ICN routers are able to take actions against these attacks. Our experiments show that the proposed solution effectively mitigates routing and caching attacks in ICN.
