【摘要】：随着无线网络技术的不断发展,基于自组织网络概念的VANET(Vehicular Ad hoc Networks)逐渐成为了近些年网络技术研究的热点。VANET作为智能交通系统的重要组成部分,在交通安全、提高道路效率、网络服务提供上都具有相当重要的地位。尽管VANET具有很高的实用前景,但现阶段对它通信安全方面的研究,仍然处于比较初级的阶段。有别于传统无线网络,VANET具有节点移动速度快、建立连接时间短、环境开放性强的特点。这些特点使得VANET容易受到匿名者的攻击。本文首先对VANET所使用的WAVE通信协议进行了研究和分析。WAVE(车载环境下的无线网络)通信协议是由电气和电子工程师协会制定的专门应用于车载互联网络的通信协议。它包括IEEE802.11p协议和IEEE 1609协议族两个部分,定义了车联网的物理层和数据链路层。之后本文研究了 DoS攻击在WAVE协议环境下的应用,扩展了 DoS攻击概念。将DoS攻击扩展为攻击无线网络的部分和攻击交通网络两个部分。在攻击无线网络部分,由于WAVE协议的特性,安全消息传输过程天然免疫多种DoS攻击手段。文章选择Flooding作为DoS攻击的基础模型,测试了多个变量中的攻击效果。攻击交通网络部分,文章从三个角度入手,分别强化了攻击消息内容、攻击展开时间和攻击节点身份,实现更具杀伤力的攻击方案。本文搭建了基于Omnet++,SUMO和Veins的仿真模拟环境,并在仿真环境中成功实现了基于实际道路模拟的交通模型。之后基于不同维度考察了仿真状态下DoS攻击对VANET的影响,并实现了设计的多种攻击方案,验证了 VANET仍然存在的安全问题和漏洞,提出需要继续完善的发展方向。在文章的最后,对本文仿真实验中的问题进行了总结和归纳,并对VANET的未来网络防御的发展方向提出一点自己的思考。
[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.
