Sammanfattning
Vehicular networks are becoming more popular every day. There are several applications of vehicular networks which are discussed by manufacturers and also academics which will be both time and money saving. Due to the growing interest in distribution of traffic and road information among drivers and connecting vehicles to other networks such as the Internet, vehicular ad hoc networks (VANET) are the topic of interest among many manufacturers and academics. There have been numerous solutions and methods in order to improve the efficiency, privacy and security of such networks. On the other hand, in-vehicle networks are formed recently to add more functionality and options to vehicles. Furthermore, subjects such as remote firmware updates of in-vehicle networks have drawn a lot of attention as well. Security, however, has always been an issue in vehicular networks which must be seriously considered and a security infrastructure has to be designed and implemented in such networks. In this work, we have done a survey of existing approaches to solve the problems associated with vehicular networks. We discuss security vulnerabilities in vehicular networks and their countermeasures, both in inter-vehicle (VANET) and in-vehicle networks, in order to secure the vehicular networks. In our work, we found that vehicular networks in general have several vulnerabilities and are exposed to different cyber attacks. There are a number of suggested countermeasures which will provide short-term security for vehicular networks. Cyber attacks in in-vehicle networks can be a threat to the vehicle and its passengers; therefore, security issues must be carefully addressed in in-vehicle networks. We believe that there will be a need for a new infrastructure to deal with current vulnerabilities in in-vehicle networks. By doing so, current and future advancements in vehicular networks can be applied with less security issues and risks which will culminate in secure and reliable vehicular networks.
