VANET Intrusion Investigation Based Forensics Technology: A New Framework

VANET is an Ad-hoc vehicular network that refers to a group of vehicles that are connected to each other through a wireless network. It is vulnerable to various network attacks due to its characteristics with high mobility and shared wireless medium. Security become a critical factor to secure traffic management in VANET. One small gap in the VANET security can cause big damage as human life is involved in this application. There are various security techniques such as Blockchain technology, Intrusion Detection System (IDS) and Forensics technology that can provide an innovative solutions to guarantee privacy, integrity, confidentiality and other security issues. In this paper, we review the recent literature works on the development of secure architecture for VANET environment. Based on our findings, we propose a new framework based on blockchain, IDS and forensics technologies to ensure authenticity, privacy and integrity. The framework consists of four main layers: the first layer apply blockchain technology for authentication purpose, second layer group VANET nodes into a set of clusters to avoid data collision, third layer deploy an IDS based artificial intelligence methods to detect internal attack and the last layer apply forensics technology for to collect and store trustworthy evidence for investigation.
