Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0022] The first solution of the present invention is to provide a working method of the server, which includes the following steps: the server issues an upgrade package; the server judges whether the communication channel of the vehicle terminal is opened; if the communication channel of the vehicle terminal is opened, the server The upgrade package is encrypted, and the encrypted upgrade package is transmitted to the vehicle-mounted terminal through the communication channel in a secure transmission manner.

Abstract

The invention provides a working method of a server, and the working method comprises the following steps: the server issues an upgrading package; the server judges whether a communication channel ofa vehicle terminal is turned on; if the communication channel of the vehicle terminal is turned on, the server encrypts the upgrading package, and transmits the encrypted upgrading package to the vehicle terminal through the communication channel by a secure transmission mode. According to the method provided by the invention, by functions of an encrypted communication module and a feedback verification module, malicious tampering to the upgrading package or an installation package caused by illegal attacking is avoided, consequently, illegal invasion of the tampered upgrading package to the vehicle terminal, a power control unit, a vehicle owner personal privacy, an information entertainment system, and so on, can be avoided, a problem of existence of hidden security danger in a remote upgrading process of motor vehicles is eliminated, and security and reliability of downloading the upgrading package over the air is guaranteed.

Description

technical field [0001] The invention relates to the technical field of motor vehicle communication, in particular to a working method of a server, an upgrading method and system of a vehicle terminal. Background technique [0002] With the increasing electronicization of motor vehicles, whether the vehicle encounters a software failure or a software update, the current offline store recall mode is no longer the best choice to satisfy the user experience. In order to reduce costs and improve user experience, OTA (Over-the-Air) upgrade technology has become an essential skill in the era of smart vehicles. However, it is precisely because of the gradual deepening of the networking of infrastructure such as vehicles and vehicles, vehicles and the Internet, and vehicles and roads, potential intrusion points and vulnerabilities have also increased geometrically, so vehicle network security issues have reached a point that cannot be ignored. OTA is considered to have the potential...
