I. INTRODUCTION
ITS cover a wide range of concepts, systems and applications of advanced and emerging technologies in transportation in order to improve road traffic safety security. While ITS becoming mainstream, cybersecurity issues have become a fundamental concern. Attacks to cyber-physical systems have targeted institutions and infrastructure around the world, and the frequency and severity of attacks are on the rise [18], [19]. Cybercriminals exploit the poorer security of the IoT (Internet of Things) devices, with compromised devices leading to a wide range of security threats such as data leakage, identity theft, and physical damage to the ITS eventually increase the risk of life [19].
