Leveraging blockchain technology to assure security of SDN

Abstract

Software-defined networking is a new way of managing how computer networks behave, it gives more ability to manage the network nodes, facilitates policies enforcement, provides more speed in applying configurations on network nodes, it has one point of controlling which is laying in the control plane represented by the controller which is the only brain for the network which provides flexibility and single point of administration but, in the same time this situation from a security point of view this could be a single point of failure so, as restriction of the control in the network by the control plane is a good security feature, it could also open new security challenges and here comes our research secure software-defined networks in order to assure the security of computer networks in general.
