Abstract: With the continuous development of the Internet of Vehicles business system, the role of vehicle control APP as a bridge between users and car companies is becoming more and more important. Then the pre-research on the safety of vehicle control APP is very important to the overall safety of Internet of Vehicles. Therefore, the article analyzes the assembly code structure of the vehicle control APP, and at the same time uses the virtual machine transcoding engine to transcode and protect the smali assembly code of the vehicle control APP to form Native C/C++ code. Finally, experiments show that this method can effectively resist reverse analysis. After transcoding, the smali assembly code will not have the ability to be restored, but also play a role in preventing secondary packaging and anti-theft version, so as to protect the vehicle IVI application code.
