There might be some potential security problem according to the features of Vehicle Ad hoc networks(VANET), including wireless, shift, scatter, developments and bandwidth limitations. The security analysis shows that the program proposed in this paper can better meet the security requirements of VANET. The advice is that the VANET is divided into several subnets based on geographic region, and the traffics in the same subnet communicate with each other through the CA (certificate authority) authentication mechanism while the communications among the subnets need the establishment of CA recommendation trust model.
