Internet of Vehicles safety communication method, vehicle-mounted terminal, server and system

Abstract

The application provides an Internet of Vehicles safety communication method, a vehicle-mounted terminal, a server and a system. The Internet of Vehicles safety communication method is characterized by comprising the following steps: the vehicle-mounted terminal sends a handshake authentication request to a server after determining that the transmission control protocol connection with the server has been finished, wherein the handshake authentication request comprises an identifier of the vehicle-mounted terminal and a first Hash value encrypted by use of a symmetrical encryption algorithm same as that adopted by the server; the vehicle-mounted terminal receives an authentication response message returned by the server, wherein the authentication response message is returned by the server after determining that the vehicle-mounted terminal is legal; and the vehicle-mounted terminal establishes a safety authentication transmission protocol connection with the server according to the authentication response message. A lightweight safety authentication transmission protocol is established between the vehicle-mounted terminal and the server by use of less resource, and the security of the data transmission between the vehicle-mounted terminal and the server is improved.

Description

technical field [0001] The present application relates to the technical field of the Internet of Vehicles, and in particular to a secure communication method for the Internet of Vehicles, a vehicle-mounted terminal, a server and a system. Background technique [0002] With the gradual maturity of Internet access technology for automobiles, the functions of network-based in-vehicle applications have also been greatly enriched and expanded, all of which have laid the foundation for the prosperity of the Internet of Vehicles application market. However, a subsequent problem that cannot be ignored is the security issue. How to ensure the security of the sensitive information that the vehicle interacts with the outside world through the network (that is, transmission security) has attracted great attention. If the transmission security is not guaranteed, sensitive data will be stolen, tampered with, and even the vehicle will be remotely controlled, which will greatly threaten the...
