A survey of vehicular ad-hoc network security

Abstract

A variety of functional control of vehicles has developed along with information and communication technology. In particular, with the application of wireless network for real-time information offering, it has been possible to establish Vehicular Ad-hoc Network (VANET), an intelligent vehicle service for convenience and safety, which makes possible collision accident warning and avoidance, warning of dangerous factors on road, traffic information offering, and other kinds of service offering. However, the VANET service environment has physical and technical vulnerabilities caused by the vehicular internal/external communication based on wireless network. Therefore, Vehicular Security has emerged as an essential factor to prevent malicious threats and privacy violation from vehicles, drivers, and traffic network. This study tries to find the main security components of the VANET environment, analyze the latest research trend to overcome security vulnerabilities in each area, and propose the future research direction of Vehicular Security.
