Advanced Security Attacks on Vehicular AD HOC Network (VANET)

Abstract

VANET is becoming an emergent technology in Intelligent Transportation Systems. Their main purpose is to provide road safety and improve driving experience for both drivers and passengers. Other unique features of VANET include dynamic topology, short connection period, high mobility of nodes, etc However, security and privacy becomes major issues when communicating in such open wireless environment. In this paper, along with VANET characteristics, we presented security requirements and challenges that need to be kept in mind while designing a security protocol. We defined all existing security attacks and privacy issues in VANET. We categorized these security attacks into different classes based on their properties and provided the comprehensive analysis on them.
