A secure remote update method for connected vehicles based on two-way identity authentication

Abstract

The present invention relates to the field of information security of intelligent networked automobiles. A method for remotely updating networked automobile security based on two-way identity authentication is applied to an automobile OTA system. The automobile OTA system includes a cloud system and a vehicle-mounted terminal system. The cloud system includes an OEM server and software. The supplier server, the vehicle-end system includes an update gateway and an electronic control unit; the OEM server completes the identity authentication of the vehicle and issues the update authority of each electronic control unit to the corresponding software supplier; the update gateway obtains software update information from the OEM server, And perform identity verification, after obtaining the identity password and the information of the software supplier, download the software update packages of different electronic control unit ECUs from the corresponding software supplier server; after the electronic control unit obtains the software update package, install its own software and Operation; the advantage of the present invention is: carry out safety protection to the whole life cycle of automobile software update.

Description

technical field [0001] The invention relates to the field of intelligent networked vehicle information security, in particular to a method for remotely updating networked vehicle security based on two-way identity authentication. Background technique [0002] The development of Internet of Vehicles and autonomous driving technologies brings convenience to automobiles. For example, automobile applications can be expanded to more scenarios such as payment, social networking, and entertainment, but at the same time, corresponding information security threats are also increased. Every interface between the car and the outside may be exploited, and every control unit may be attacked. The reason is that compared with traditional cars, intelligent networked vehicles involve more on-board software codes (hundreds of millions of lines of codes), more networked electronic control units (70+ECUs), more sensors, hardware and software function expansion The corresponding information sec...
