Description

Data security upgrading method and device for vehicle-mounted equipment and electronic equipment Technical Field The present invention relates to the field of network security of vehicle-mounted devices, and in particular, to a method and apparatus for upgrading data security of a vehicle-mounted device, an electronic device, a computer storage medium, and a program product. Background With the rapid development of automobile technology, the network security problem of the vehicle-mounted equipment is increasingly prominent. Modern automobiles not only have a high degree of intelligence, but also enable a wide connection to the internet and other devices, which makes them subject to serious risks from network attacks. Hackers may unauthorized access the vehicle control system, possibly through vulnerabilities, malware, or other means, thereby resulting in security risks. Therefore, in recent years, related departments of various countries have sequentially introduced a series of regulations and standards to strengthen the network security of the vehicle-mounted devices and ensure that the vehicle communication system, user data and driving safety are effectively protected. For newly developed and produced vehicle-mounted equipment, enterprises can formulate and perfect security policies in the development and production stages so as to ensure that the vehicle-mounted equipment has the capability of resisting potential network attacks. However, how to effectively update the on-board devices that have come down the production line to meet the latest network security standard without affecting the existing parameter configuration is still a challenge to be solved. Disclosure of Invention The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a method, an apparatus, an electronic device, a computer storage medium, and a computer program product for securely upgrading data of a vehicle-mounted device, which can adjust network security configuration of a part of data in a vehicle-mounted device on a production line without affecting existing parameter configuration. According to one aspect of the invention, a method for safely upgrading data of vehicle-mounted equipment is provided, and the method comprises the steps of deploying a safety management backup area in the vehicle-mounted equipment and setting a safety management backup mark, wherein the safety management backup mark is used for identifying whether preset data is backed up to the safety management backup area, confirming whether the safety management backup mark is an initial value when the vehicle-mounted equipment is started after upgrading is finished, copying the preset data to the safety management backup area to serve as backup data when the safety management backup mark is confirmed to be the initial value, carrying out data encryption on the backup data, and updating the safety management backup mark to be a preset value, and switching to use the backup data of the safety management backup area when the vehicle-mounted equipment needs to use the preset data. Preferably, the vehicle-mounted equipment data security upgrading method further comprises the steps of confirming whether the preset data are consistent with the backup data or not under the condition that the security management backup mark is confirmed to be not an initial value, and updating the preset data into the backup data if the preset data are inconsistent with the backup data. Preferably, the preset data is stored in a nonvolatile memory of the vehicle-mounted device, and the security management backup area is also disposed in the nonvolatile memory of the vehicle-mounted device. According to another aspect of the invention, a vehicle-mounted equipment data security upgrading device is provided, which comprises a setting module, a confirming module, a backup module and a switching module, wherein the setting module is used for deploying a security management backup area in the vehicle-mounted equipment in the upgrading process and setting a security management backup mark, the security management backup mark is used for identifying whether preset data is backed up to the security management backup area, the confirming module is used for confirming whether the security management backup mark is an initial value when the vehicle-mounted equipment is started after upgrading is completed, the backup module is used for copying the preset data to the security management backup area to serve as backup data when the security management backup mark is confirmed to be the initial value, and carrying out data encryption on the backup data to update the security management backup mark to a preset value, and the switching module is used for switching the backup data of the security management backup area when the vehicle-mounted equipment needs to use the preset data.
