Data Hiding based PKI Authentication Protocol in SDN

Abstract

Software Defined Network (SDN) is a potential solution to classical network problems like binding all the three network planes like Data plane, Control plane and Management plane into one device. This gives rise to a huge problem of vendors’ lock-ins who tie up networking protocols specific to machine which makes interoperability  a big issue. Lack of modularity in the routing protocols where routing code is embedded into network topology code and change in infrastructure becomes difficult is one of the various factors that motivated the development of SDN. Security in SDN is completely different from security in the old networks. In this paper, we assess how host authentication is badly affected on machines on Software Defined Networks. Moreover, this paper also defines how authentication has been hampered and what the various authentication protocols are and how we can try to identify a hacker. In the nutshell, our paper presents the various challenges, problem in deploying various authentication protocols and how we can move ahead with secure deployment.
