Abstract
Software Defined Networking (SDN) is being extensively adopted by researchers and enterprise networks due to its feature of decoupling data and control planes from network device which enables them to implement new networking ideas. Communication between data and control planes faces various security issues where many users in data plane approach controller device in control plane to gain networking policies. In this paper, we proposed an efficient Zero-knowledge proof based identification scheme for securing SDN controller during data and control plane communication. This scheme ensures that only users who prove their knowledge about secrecy without revealing actual secret or any other information about it can communicate with controller. The computation cost was calculated to validate efficiency of the proposed work and compared with scheme that works in the basis of Kerberos authentication protocol.
