Networked automobile safety remote updating method based on bidirectional identity authentication

Abstract

The invention relates to the field of intelligent networked automobile information security, in particular to a networked automobile security remote updating method based on bidirectional identity authentication, which is applied to an automobile OTA system. The automobile OTA system comprises a cloud system and a vehicle-mounted terminal system; the cloud system comprises an OEM server and a software supplier server, and the vehicle-mounted terminal system comprises an updating gateway and an electronic control unit; the OEM server completes the identity authentication of the vehicle and issues the updating authority of each electronic control unit to the corresponding software supplier; the updating gateway acquires the software updating information from the OEM server, performs identity verification, and downloads software updating packages of different electronic control units (ECU) from the corresponding software supplier server after acquiring the identity password and the information of the software supplier; and the electronic control unit is used for installing and operating own software after acquiring the software update package. The method has the advantage that safety protection is carried out on the full life cycle of automobile software updating.

Description

Technical field[0001]The present invention relates to the field of intelligent network car information security, and in particular to a two-way identity authentication network-based automotive security remote update method.Background technique[0002]The vehicle network, automatic driving technology is developed to the car, such as automotive applications to expand more scenes such as payment, social, entertainment, but also add corresponding information security threats. Each interface of the car and the outside may be utilized, and each control unit may be attacked. The reason, the intelligent network car relative to traditional cars, involving more in-vehicle software code (hundreds of millions of lines of lines), more network electronic control units (70 + ECU), more sensors, hardware and software function expansion The corresponding information security threat increased during the process. Attackers can remotely launch cyber attacks, causing the leakage of personal privacy data a...
