摘要： 将软件定义网络应用于车联网能显著提升其性能，但该方法也面临传统SDN要应对的安全问题。基于软件定义车联网体系架构中控制平面可能面临的针对性节点攻击问题，提出一种鲁棒的控制器放置方法。该方法结合传统的SDN控制平面部署问题，首先将控制平面鲁棒性问题建模为交换机与控制器的连通冗余性问题，提升交换机在极端情形下与控制器的连通性；其次设计一个鲁棒性指标，以衡量控制平面鲁棒性。仿真结果表明，该方法的鲁棒性要优于基于时延可靠性的部署方案。

Robust control plane scheme in SDVN toward targeted attack

Abstract： Applying software-defined networking to the Internet of Vehicles can significantly improve its performance. However, this method also faces security issues that traditional SDN has to deal with. This paper proposes a robust controller placement method based on the targeted node attack problem that the control plane may face in the software-defined vehicular networking architecture. This method combines the traditional SDN control plane deployment problem. Firstly, the control plane robustness problem is modeled as the connectivity redundancy problem between the switch and the controller. Secondly, a robustness metric is designed to measure the robustness of the control plane. The simulation results demonstrate that the robustness of this method is better than the deployment scheme based on delay reliability.
