An Ant Colony Algorithm Based Content Poisoning Mitigation in Named Data Networking

Abstract

Content Poisoning in Named Data Networking (NDN) can greatly reduce the effect of ubiquitous data caching, which is a prominent feature in NDN. Especially, when the NDN routers are compromised by attackers, finding a suitable scheme to mitigate such content poisoning in NDN routers is a challenge. In this paper, we proposed a scheme named Ant Colony Algorithm Based Content Poisoning Mitigation (ACO-CPM) in NDN. This scheme introduces the ACO to probe the safety transmission path and adjust the content retrieval process, by collecting the security information of all routers on the whole path. Meanwhile, the ACO-CPM can bypass the evil routers and therefore prevent the evil routers distributing illegal content any more. Plus, the proposed scheme can mitigate content poisoning by clearing bogus Data packets in the cache store during the path finding process. We implement our scheme by comparing it with ROM scheme in ndnSIM simulator. Simulation results show that our scheme can alleviate the content poisoning attacks caused by evil routers quickly and effectively.
