SECURITY STUDY OF ROUTING ATTACKS IN VEHICULAR AD-HOC NETWORKS (VANETS)

[摘要] The Vehicular Ad-hoc Network (VANET) is a fast-growing and highly motivated area of research to provide Intelligent Transport Systems (ITS) services to end-users; these services are also responsible for providing an efficient driving environment. in VANET networks, several routing protocols have been designed, but still networks are vulnerable to many threats in the presence of malicious nodes. Today, security is a major challenge in various VANET applications where a bad message can directly or indirectly affect human lives. In this paper, we examine some routing attacks such as Black hole & Wormhole attacks, as well as available solutions for such attacks in existing VANET protocols.
