The Internet of Vehicles (IoV) is a part of the Internet of Things (IoT). With the continuous development of the Internet of Things technology, the Internet of Vehicles technology has also made great progress. However, as more and more vehicles are connected to the Internet of Vehicles, the calculation and transmission of data in the Internet of Vehicles becomes more and more difficult, and at the same time, it is inevitable to face the pressure of data security and privacy protection. In order to solve the above problems, academia and industry have adopted many methods, combining mobile edge computing technology with the Internet of Vehicles to establish a vehicle edge computing network to solve the problems of data computing and transmission. Introducing blockchain technology and federated learning technology into vehicle edge computing. Therefore, the network addresses the issues of data security and privacy protection. Based on these, this paper summarizes the research results of many scholars in related fields, in order to provide reference and reference for subsequent related research.
