Abstract

An intelligent transportation system (ITS) is a well-developed program that aims to provide innovative assistance in identifying various methods of transportation and traffic management. It is empowering clients to be better educated and make more secure, increasingly prepared, and 'more intelligent utilization of transport systems. Internet of Vehicles (IoV) is a rising idea in ITS to upgrade the current abilities of Vehicular Ad-hoc Networks by incorporating them into the Internet of Things. IoV has commanded the vehicular frameworks because of various exceptional characteristics like dominant topographic network structures, massive network proportion, consistent internet connection, a similarity of individual gadgets, and elevated handling ability. An intelligent transportation framework includes a gigantic measure of transforming real-time critical information, in which security plays a significant part. In this chapter, an investigation of IoV and VANETs has been conducted, with distinctive security aspects of IoV being emphasized, incorporating security requirements, security risks, and security attacks. Finally, persisting current lightweight cryptographic security solutions for IoV related attacks are summarized.
