Problems solved by technology
[0003] However, the current remote vehicle upgrade solutions do not or rarely take proper security protection measures, which may easily cause security issues such as the upgrade data being tampered with or implanted with malicious code by a third party, or causing vehicle failures that affect the use, serious Tragedy caused by car crash
At the same time, due to the lack of encryption protection for the upgrade data, it is easy for the competitor of the vehicle manufacturer or a malicious third party to intercept the plaintext of the upgrade data package, so as to analyze the existing or potential defects of the vehicle and the possibility of further attacks

The invention discloses a secure remote upgrade system and upgrade method for vehicles. The system comprises an upgrade pack server, a vehicle-mounted terminal, a remote upgrade server and a key server. The upgrade method comprises following steps: 1, the upgrade pack server calls an upgrade pack secure processing module to carry out secure processing on preset vehicle upgrade data and then upload the data to the remote upgrade server; 2,the vehicle-mounted terminal and the remote upgrade server interacts with the key server to obtain vehicle upgrade data; 3, the vehicle modules to be upgraded are upgraded by means of the vehicle upgrade data. According to the secure remote upgrade system and upgrade method for vehicles of the invention, through the addition of the hardware-security-chip-based secure module to the upgrade pack server and the vehicle-mounted terminal and the combination of the key server and the remote upgrade server, encryption and digital signature and verification services are provided for the data upgrading and the confidentiality and integrity of data upgrading are guaranteed.
Description
technical field [0001] The invention relates to the technical field of vehicle remote upgrade, in particular to a vehicle safety remote upgrade system and an upgrade method. Background technique [0002] With the improvement of wireless network coverage, the popularity of smart vehicle terminals, and the wide application of vehicle MCU or ECU, people's demand for intelligent vehicles is getting higher and higher. At present, it is already possible to remotely upgrade the vehicle MCU or ECU. The remote upgrade of the vehicle MCU or ECU can solve the problems existing in the MCU or ECU in a timely manner, help vehicle manufacturers reduce the cost of the upgrade, and at the same time bring convenience to users and improve user satisfaction with vehicles and manufacturers. [0003] However, the current remote vehicle upgrade solutions do not or rarely take proper security protection measures, which may easily cause security issues such as the upgrade data being tampered with o...
