VANETs Security Issues and Challenges: A Survey

Vehicular Ad-hoc Networks (VANETs) are sought to control traffic, avoid accidents, and control other aspects of traffic. It (VANET) is a piece of critical infrastructure that bolsters traffic management efficiency and road safety. Nowadays, VANET applications have received a great deal of attention by the research community due to the important role that such networks can play. However, security in VANETs still remains a big challenge due to its nature. This survey paper sheds some light on VANETs’ vulnerabilities and attacks. It surveys and examines some recent security solutions along with their achievements and limitations. As a result, we conclude that security is the key to success for VANET applications, but still some critical challenges remain. Moreover, when designing a sufficient security solution; privacy preservation, productivity, and usability should be taken into account. Therefore, the door for future research is open for a lot more contributions in this filed.
