【摘要】：隨著無線網(wǎng)絡技術的不斷發(fā)展,基于自組織網(wǎng)絡概念的VANET(Vehicular Ad hoc Networks)逐漸成為了近些年網(wǎng)絡技術研究的熱點。VANET作為智能交通系統(tǒng)的重要組成部分,在交通安全、提高道路效率、網(wǎng)絡服務提供上都具有相當重要的地位。盡管VANET具有很高的實用前景,但現(xiàn)階段對它通信安全方面的研究,仍然處于比較初級的階段。有別于傳統(tǒng)無線網(wǎng)絡,VANET具有節(jié)點移動速度快、建立連接時間短、環(huán)境開放性強的特點。這些特點使得VANET容易受到匿名者的攻擊。本文首先對VANET所使用的WAVE通信協(xié)議進行了研究和分析。WAVE(車載環(huán)境下的無線網(wǎng)絡)通信協(xié)議是由電氣和電子工程師協(xié)會制定的專門應用于車載互聯(lián)網(wǎng)絡的通信協(xié)議。它包括IEEE802.11p協(xié)議和IEEE 1609協(xié)議族兩個部分,定義了車聯(lián)網(wǎng)的物理層和數(shù)據(jù)鏈路層。之后本文研究了 DoS攻擊在WAVE協(xié)議環(huán)境下的應用,擴展了 DoS攻擊概念。將DoS攻擊擴展為攻擊無線網(wǎng)絡的部分和攻擊交通網(wǎng)絡兩個部分。在攻擊無線網(wǎng)絡部分,由于WAVE協(xié)議的特性,安全消息傳輸過程天然免疫多種DoS攻擊手段。文章選擇Flooding作為DoS攻擊的基礎模型,測試了多個變量中的攻擊效果。攻擊交通網(wǎng)絡部分,文章從三個角度入手,分別強化了攻擊消息內容、攻擊展開時間和攻擊節(jié)點身份,實現(xiàn)更具殺傷力的攻擊方案。本文搭建了基于Omnet++,SUMO和Veins的仿真模擬環(huán)境,并在仿真環(huán)境中成功實現(xiàn)了基于實際道路模擬的交通模型。之后基于不同維度考察了仿真狀態(tài)下DoS攻擊對VANET的影響,并實現(xiàn)了設計的多種攻擊方案,驗證了 VANET仍然存在的安全問題和漏洞,提出需要繼續(xù)完善的發(fā)展方向。在文章的最后,對本文仿真實驗中的問題進行了總結和歸納,并對VANET的未來網(wǎng)絡防御的發(fā)展方向提出一點自己的思考。
[Abstract]:With the development of wireless network technology. VANET(Vehicular Ad hoc Networks based on the concept of Ad hoc Networks. As an important part of intelligent transportation system, VANET has gradually become a hotspot of network technology research in recent years. VANET has a very important position in traffic safety, improving road efficiency and providing network service. Although VANET has a high practical prospect, it is studied in the field of communication security at this stage. Different from the traditional wireless network, VANET has fast node moving speed and short connection time. These characteristics make VANET vulnerable to anonymous attacks. Firstly, this paper studies and analyzes the WAVE communication protocol used by VANET. Wireless network in vehicular environment). Communication protocol is a communication protocol developed by the Association of Electrical and Electronic Engineers which is specially applied to the vehicular Internet. It includes two parts: IEEE802.11p protocol and IEEE 1609 protocol family. The physical layer and data link layer of vehicle networking are defined. Then the application of DoS attack in WAVE environment is studied. The concept of DoS attack is extended. The DoS attack is extended to attack the wireless network part and the attack traffic network part. In the attack wireless network part, because of the characteristic of WAVE protocol. In this paper, Flooding is chosen as the basic model of DoS attack, and the attack effect of multiple variables is tested. From three angles, this paper strengthens the content of the attack message, attack launch time and attack node identity to achieve a more lethal attack scheme. This paper built based on Omnet. The simulation environment of SUMO and Veins. The traffic model based on actual road simulation is successfully implemented in the simulation environment, and then the influence of DoS attack on VANET in simulation state is investigated based on different dimensions. And the design of a variety of attack schemes to verify the security problems and vulnerabilities that still exist in VANET, put forward the need to continue to improve the direction of development. At the end of the article. This paper summarizes and summarizes the problems in the simulation experiment in this paper, and puts forward some thoughts on the future development direction of VANET network defense.
