Selecting Bloom-filter header lengths for secure information centric networking

Information-centric networking (ICN) is a new communication paradigm that shifts the focus from end hosts to information objects. Recent studies have shown that ICN can provide more efficient mobility support and multicast/anycast content delivery compared to traditional host-centric solutions. Nevertheless, the ICN solutions proposed so far are not very mature from the security viewpoint. In this paper, we study one of the most important Bloom-filter based ICN forwarding mechanisms and discuss its security vulnerabilities. Next, we propose some enhancements to this mechanism, which aim at increasing its resistance to brute-force attacks. Our proposed solutions are supported by simulation studies.
