VANET’S SECURITY REQUIREMENTS AND ATTACKS - A REVIEW

Vehicular Ad hoc Networks (VANETs) have emerged as one of the most promising topics for researchers and automotive industries due to their remarkable potential to improve traffic safety, efficiency and other added services. Communication using VANETs is commonly seen as the next milestone for improving traffic safety. Â Vehicles will be enabled to exchange any kind of information that helps to detect and mitigate dangerous situations. However, VANETs are themselves exposed against attacks that can directly lead to the corruption of networks and then possibly exacerbate big losses of time, money, and even lives.Subject of this work is to recognize the attackers that target active safety applications in VANETs. Through a risk analysis, this work identifies assets, threats and possible attacks in inter-vehicle communication. The risk analysis shows that the most serious threat arises from a road- side attacker that distributed fake warning messages. This paper presents a review of various VANETs security requirements attacks
