This paper proposes the security architecture of cloud computing data center based on SDN. The application of SDN in cloud computing data center is analyzed and the OpenFlow protocol is studied. The system completes the framework design of SDN security controller from three aspects: layered security, communication security and cloud computing control center security. Then this paper proposes a dynamic cloud security storage mechanism based on data drift technology. The storage mechanism first divides the files to be stored into data particles and stores them in different network nodes. Data particles are then driven to continuously and randomly "drift" between storage nodes. File read nearby clustered download delivery. The platform can directly deploy software to run in the cloud without modifying traditional software. Simulation results show that the architecture can ensure high data security and improve the overall performance of the system.
