摘要: 將軟件定義網(wǎng)絡(luò)應(yīng)用于車聯(lián)網(wǎng)能顯著提升其性能,但該方法也面臨傳統(tǒng)SDN要應(yīng)對(duì)的安全問題?;谲浖x車聯(lián)網(wǎng)體系架構(gòu)中控制平面可能面臨的針對(duì)性節(jié)點(diǎn)攻擊問題,提出一種魯棒的控制器放置方法。該方法結(jié)合傳統(tǒng)的SDN控制平面部署問題,首先將控制平面魯棒性問題建模為交換機(jī)與控制器的連通冗余性問題,提升交換機(jī)在極端情形下與控制器的連通性;其次設(shè)計(jì)一個(gè)魯棒性指標(biāo),以衡量控制平面魯棒性。仿真結(jié)果表明,該方法的魯棒性要優(yōu)于基于時(shí)延可靠性的部署方案。

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.
Key words : software-defined vehicular networking(SDVN);controller placement;robustness;targeted attack

    隨著車聯(lián)網(wǎng)的蓬勃發(fā)展,車載自組織網(wǎng)絡(luò)(Vehicular Ad-hoc Network,VANET)受到工業(yè)界和學(xué)術(shù)界的極大關(guān)注。VANET中異構(gòu)無線技術(shù)靈活性、可編程性、共存性的特點(diǎn),以及5G架構(gòu)中的資源管理等可利用SDN(Software-Defined Networking)的方式來實(shí)現(xiàn)[1]。

軟件定義車聯(lián)網(wǎng)(Software-Defined Vehicular Networking,SDVN)結(jié)構(gòu)組成與SDN相似。其中控制平面由管理和控制整個(gè)網(wǎng)絡(luò)的SDN控制器組成,數(shù)據(jù)平面由各種交換設(shè)備組成,在節(jié)點(diǎn)間實(shí)現(xiàn)數(shù)據(jù)轉(zhuǎn)發(fā)。數(shù)據(jù)平面又分為上層數(shù)據(jù)平面和下層數(shù)據(jù)平面。上層數(shù)據(jù)平面包括支持OpenFlow協(xié)議的交換機(jī)和路由器,以及無線接入設(shè)施,如路邊單元、基站等;下層數(shù)據(jù)平面由車輛終端用戶配備的車載單元組成。與SDN類似,盡管分布式控制平面[2]已成為SDVN架構(gòu)的主流設(shè)計(jì),將控制功能集中于控制層仍然存在遭受惡意攻擊的風(fēng)險(xiǎn)。

    以軟件定義方式解決車聯(lián)網(wǎng)安全問題有效且富有挑戰(zhàn)性,其不僅要解決傳統(tǒng)VANET的安全問題[3-4],同時(shí)也要解決上層數(shù)據(jù)平面以上的安全問題。
