The SDN (Software Defined Network) characteristics of logically centralized control and programmability contribute on resolving security management and control problems of networking comprehensively and flexibly, however, there are still considerable issues presented by itself remaining to be solved. Based on the analysis of SDN architecture and security, this paper works on the security of south channel and gives a secure solution based on the OTR protocol. The proposed method has the forward security and safety certification characteristics, which can give a solution to the SDN for the security of authentication, key security save and SDN component hidden protection.
