The Software Defined Network (SDN) architecture decouples the control functionality from the forwarding devices and implements it in a separate entity known as the controller. This raises new concerns on securing the control messages exchanged between the controller and the forwarding devices. In this paper, we propose TopoTrust, a novel fully trustless authenticity and integrity verification mechanism that relies on a Blockchain protocol to detect network topology poisoning attacks, namely Host Tracking Service (HTS) and OpenFlow Discovery Protocol (OFDP). The key merit of TopoTrust is its ability to operate in a zero trust SDN environment where no controller or switch is trusted. The evaluation of our protocol shows that it can successfully detect any spoofing-based and packet tampering attacks; and up to 96% and 100% of Fast Relocation and Link Fabrication attacks respectively within a short detection time, while introducing small overhead to the network. |
