Abstract

Information needs are increasing from year to year. It is therefore crucial that we obtain information as soon as the need arises. The focus of my thesis shall concentrate on the area of vehicular networks. Vehicular networks are essentially similar to all other fixed networks: they share some components, but also have some significant differences. The main differences include various sensors, which are found in vehicles and the way nodes connect to the network, which mainly occurs when travelling at higher speeds. In the first part of this work I will list various technologies which enable functioning of such networks, as well as their different possible layouts. In the central part, I will focus on applications that drive such networks to evolve. Here I will also present a variety of such applications. I will then dedicate the following chapter of this thesis to security, a key aspect of the vehicular network. I will present a range of security challenges and requirements in terms of network planning, as well as safety requirements with regards to applications. Finally, I will present the different possible attacks on vehicular networks and applications used in this type of network, and define attacker types. The work concludes with advice on countermeasures that could be taken to ensure higher level of security and more resilience against attackers.
