A Survey on VANET attacks and its Security Mechanisms

There has been a recent surge in interest in wireless related VANETs, which are swiftly rising to the top of the priority research list for the smart-transportation system. Such system offers protection and safety measures for both driver and traveler. VANETs differ greatly from mobile ad-hoc-networks in terms of uniqueness, issues, system-design, and application. We address the architecture, security, and problems of VANETs in this study, which summarizes recent state-of-the-art solutions. Second, we go over a detailed study of security systems as well as potential solutions for ensuring secure communication in VANETs. Then, we go over all of the authentication systems that can safeguard the vehicular network from malicious nodes and other threats. This paper discusses about various attacks in VANETS and the security methods used to detect the attacks in real time. The attacks that are considered are collision attacks, sybil attacks, black-hole attacks, and jamming attacks. The security of the network is assured by detecting the threats in a timely manner.
