Research and Application of Information Security Technology in New Energy Vehicle Based on Mobile Internet

With the development of artificial intelligence, automobile access to mobile internet has become a trend of development. Because the CAN bus of automobile adopts the data transmission mode of open code broadcast, there is a great risk to the information security in the vehicle. In view of this situation, the author develops a data encryption transmission protocol based on OBD, optimizes the bus topology of automobile electronic zero, and designs a comprehensive body control system starting with the research of CAN bus security. The system effectively integrates the current ECU nodes of the new energy vehicle body and reduces the bus load rate of the vehicle body. By combining with the encryption service specification, the system can better realize the security protection of the information inside the vehicle, and has a broad market prospect.
