Abstract

Vehicular Ad-Hoc Network (VANET) is an application of Ad-Hoc Network, which can significantly improve the efficiency of transportation systems. The authentication of information is particularly important in the VANET system, because of its significant impact, and the transportation systems may be paralyzed as a result of receiving the wrong traffic information. Hence, a lot of schemes have been proposed to verify the information of VANET. However, most of currently known schemes verify the information on a one by one basis. In real situation, the large amount of traffic flow will generate a lot of information at the same time. If the authentication method is authenticating one by one, it is bound to lead to information delays, and the system will have difficulty to achieve real-time performance. Therefore, we shall propose an improved authentication of the batch scheme based on bilinear pairing to make VANET more secure, efficient, and more suitable for practical use.
