Security in vehicular ad-hoc network with Identity-Based Cryptography approach: A survey

The number of vehicles on the road has increased in recent years. Due to the high density of all these vehicles, potential threats and road accidents are increasing. Wireless technology is designed to equip in-vehicle technology in order to reduce these factors by sending messages to each other, known as vehicular ad hoc networks or VANET. The optimal goal of this study is that vehicular networks will contribute to safer and more efficient roads in the future by providing timely information to drivers and concerned authorities. Thus to meet this goal, substantial research in the area of security is required in order to make the VANET deployment possible in near future. In terms of architecture, implementation of Identity Based Cryptography (IBC) schemes has been studied in order to provide better security and privacy for VANET, as it is considered a viable choice due to the properties of VANET compared to the traditional Public Key Infrastructure (PKI) approach.
