  • Abstract For transmitting messages between vehicles, there are more and more researches about vehicular ad-hoc network (VANETs) which is proposed in recent year. Every vehicle transmits message by the On-Board Unit (OBU) which is set on the vehicle. When vehicle encounters the traffic accident or traffic congestion, it can notify other vehicles to avoid these road conditions by broadcasting message. During the transmission of messages, it may be under attack. How to ensure that message does not be tampered and the resource of message during the transmission is important. With Road Side Unit (RSU) assist, it can ensure that messages integrity and message is send by the legitimate vehicle during the transmission.
    For vehicle’s identity verification and message authentication, it must be assist by RSU. Because the cover range of RSU is restricted, the cost of installing RSU widely is high. How to resolve this problem is an import in VANETs.
    In our thesis, we apply Random Secret Pre-distribution (RSP), to research the message authentication and identity verification with RSU and without RSU. Private communication and anonymousness is also important in VANETs, and we will discuss how to achieve in our thesis.
    Combining the RSP and IBC can make the anonymous authentication easier and safer. Establishing a session key can achieve the private communication. Using HMAC can make message authentication more efficient. The performance is better than the previous related works. Because every vehicle’s anonymousness is temporary, it should register new anonymousness after RSU updating its secret pool. It will reduce the vehicle’s memory overhead.
