Port hopping is a typical technology in moving target defense which constantly changes communication port number to confuse potential attackers and protect target *** port hopping technology,time synchronization is the key problem to be solved since time synchronization can ensure communication port matching and avoid data loss in port hopping ***,in software defined network(SDN),since its architecture differs from traditional network,port hopping technology hasn't been fully applied in *** on timestampsynchronization,this paper creates a port hopping model in software defined network according to its centralized control,data plane and control plane separation as well as programmable *** timestampbased port hopping model,we design a three-party port synchronization mode by utilizing SDN controller and solve the problems in time synchronization such as clock drift and *** theoretical analysis and experimental results show that this proposed timestamp-based port hopping method can effectively resist Do S attack without adding load on SDN controller in software defined network.
