Preventing DDoS attacks in Path Identifiers-Based Information Centric Networks

Information Centric Networks (ICNs) have emerged in recent years in order to provide effective mechanisms for content distribution and retrieval. However, these future network architectures are vulnerable to Distributed Denial of Service Attacks (DDoS). In this paper, we propose an effective mechanism to counter these attacks in path identifier-based information centric networks. The proposed mechanism, called GET Message logging based filtering (GMLF), employs Bloom filter based logging to store incoming GET messages such that corresponding content messages are verified, while filtering packets originating from malicious hosts.
