Internet of vehicles system session key generation method and vehicular terminal and ECU binding method

Abstract

The invention discloses an Internet of vehicles system session key generation method. The method comprises that an Internet of vehicles platform receives key request information sent by a vehicular terminal, wherein the key request information at least comprises identifier information of the vehicular terminal; an original terminal key is generated according to the identifier information of the vehicular terminal; and a session key is generated through a root key and the original terminal key. According to the method provided by the invention, the session key is generated at the side of the Internet of vehicles platform and is not generated by the vehicular terminal; the security is relatively high; and the generation mode is simple and rapid. The invention also provides a vehicular terminal and ECU binding method, a method for preventing the vehicular terminal from being disassembled or replaced, the Internet of vehicles platform and the Internet of vehicles system. When the vehicular terminal is disassembled or replaced privately, key negotiation is failed, a full vehicle ECU issues an automatic vehicle locking instruction, and the vehicular terminal is prevented from being disassembled or replaced.

Description

technical field [0001] The present invention relates to the technical field of vehicle systems, and in particular to a method for generating a session key for a vehicle networking system, a method for binding a vehicle terminal to an ECU, a method for preventing a vehicle terminal from being removed or replaced, a vehicle networking platform, and a vehicle networking system. Background technique [0002] With the development of science and technology, the Internet of Vehicles system has become the main development direction of the future motor vehicle network. The Internet of Vehicles system uses advanced sensing technology, network technology, computing technology, control technology, intelligent technology, and safety technology to comprehensively perceive roads and traffic, and realizes the interaction of large-scale and large-capacity data between multiple systems. A real-time, accurate, efficient and safe transportation comprehensive management and control system provid...
