A survey on internet of vehicles: Applications, security issues & solutions

Internet of Vehicles (IoV) is an emerging concept in intelligent transportation systems (ITS) to enhance the existing capabilities of VANETs by integrating with the Internet of Things (IoT). IoV has dominated the transportation systems due to numerous special traits like dynamic topological structures, huge network scale, reliable internet connection, compatibility with personal devices and high processing capability, etc. In this review, an in-depth survey of IoV is carried out by discussing the applications of IoV in different areas, as well as the comparative study of IoV and VANETs, is being done. Intelligent transportation system involves a huge amount of dynamic real-time critical data so its security is a major concern. Different security aspects of IoV are studied in this review which includes security requirements, security challenges, and security attacks. After this, existing security solutions of all attacks are elaborated and discussion section is provided to highlight the drawbacks of security solutions deployed for each attack as well as it emphasizes on the attacks for which no security solutions are available. Based on the extensive study conducted on this, it has been found that existing security solutions use conventional cryptographic techniques that affect the performance of the delay sensitive network i.e. IoV and VANETs. So, a lightweight authentication protocol for RFID (Radio-Frequency Identification devices) has also been proposed to overcome the drawbacks of existing solutions and to provide better performance in terms of low detection time, low CPU and memory consumption to strengthen the existing IoV environment.
