LEVERAGING BLOCKCHAIN TECHNOLOGY TO ASSURE SECURITY OF SDN

Abstract

This article presents a potential solution to secure or ensure a better security level for the Software-Defined Networks (SDN) paradigm; by introducing the usage of blockchain technology in a different way than the Marconi protocol technology proposes. Most of the techniques and methodologies proposed by this research are to patch some security issue the SDN presents like the single point of failure, cause as SDN can provide solutions and flexibility for current computer networks; it could also promote some new security threats since it is still a relatively new technology. In this article those algorithms and methodologies are incorporated together as a full suite or a framework that can be applied as a network application for the software-defined network environment and could be implemented in the management or application plane which is the top layer in the architecture of the SDN as we will see later in this article.
