Abstract

The invention discloses a method for generating a session key of a vehicle networking system, comprising: a vehicle networking platform receiving key request information sent by a vehicle terminal, the key request information at least including identification information of the vehicle terminal; according to the The identification information of the vehicle terminal generates an original terminal key; a session key is generated through the root key and the original terminal key. In the method provided by the present invention, the session key is generated on the platform of the Internet of Vehicles instead of being generated by the vehicle-mounted terminal, so the security is high, and the generation method is simple and quick. The present invention also provides a method for binding a vehicle-mounted terminal to an ECU, a method for preventing the vehicle-mounted terminal from being removed or replaced, a vehicle networking platform and a vehicle networking system. When the vehicle-mounted terminal is removed or replaced privately, the key negotiation fails, and the vehicle ECU issues an automatic lock command to prevent the vehicle-mounted terminal from being removed 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...
