Therefore, ensuring the transmission of messages with adequate security and maintain the privacy of drivers of VANET is one of the important issues in recent years. Although there are many related researches, but how to give consideration to efficiency, privacy preserving and security synchronously still have room for improvement. This paper proposed a self-generate pseudonym mechanism with privacy preserving and satisfies the security requirements in communication of VANET, reducing the communication overhead simultaneously. Our method is better than other methods on the overall evaluation of efficiency, privacy preserving and security.
