In the SDN Network environment, certificate-based authentication is mandatory for the SDN controller to be able to authorize and authenticate the network elements. However the certificate based authentication models we have today required changes and challenges to be adapted to the SDN environments.
I will present the current problem in the certificate based authentication models with SDN environment and the possible solution to overcome those problems:

-SelfSign certificate: key management and MITM attacks.

-Certificate Authority (local and public): generate and update certificate process during production environment. Compromised CA certificate will compromise all network elements that use CA Certificate.

-Distinguish between the secure channels over different network protocols (OpenFlow, Netconf, SNMP, .etc)

-The possible solutions from the academic and industry research
