Research Area: Vehicular Ad Hoc Networks
The intelligent transportation system (ITS) is made possible and practical due to vehicular ad hoc networks (VANETs) that helps improve drivers safeties and traffic efficiency on road by interchanging traffic-related information among vehicles and infrastructures. However, due to the open wireless access medium, the security and privacy of this information become quite critical in VANETs. The attackers could capture, intercept, alter, replay and delete the traffic-related information and could compromise the security of VANETs. Therefore, to ensure security and privacy of the traffic-related information in VANETs is the hot research area of nowadays. In this context, lots of research works have been done to secure vehicular communications. However, these works did not address the security issues in terms of security requirements, security attacks, and efficiency in performance, properly. In this paper, several authentication and privacy schemes have been classified and discussed their mechanisms, strengths and limitations, security requirements, attacks, and performance parameters. Finally, we identified some open research challenges in the domain of VANETs security.
