Abstract

The invention discloses a system upgrade method, an OTA upgrade package encryption method, a terminal device and a vehicle. The system upgrade method comprises the following steps: obtaining description information of an over-the-air technology based OTA upgrade package, wherein the description information comprises a key, an OTA public key, an OTA public key signature, and a digest signature of the OTA upgrade package; downloading an OTA upgrade package encrypted by the key; decrypting the OTA upgrade package by the key; verifying the legality of the decrypted OTA upgrade package by using a pre-configured root public key, the OTA public key signature, and the digest signature of the OTA upgrade package; and storing the decrypted OTA upgrade package, and performing system upgrade accordingto the decrypted OTA upgrade package if the OTA upgrade package is judged to be legal. The system upgrade method can ensure that the OTA upgrade package is not easily maliciously changed during the transmission process, and can ensure the integrity of the upgrade package, so as to verify the accuracy, thereby improving the security of the system upgrade.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a system upgrade method, an OTA upgrade package encryption method, terminal equipment and a vehicle. Background technique [0002] With the development of the Internet of Things, intelligent terminals such as smart homes, smart vehicles, and traditional equipment are the future development trend. The over-the-air technology (Over-the-Air Technology, OTA) upgrade is to solve the problem of system upgrade and optimization of smart terminals. The OTA upgrade mainly refers to a method of remotely managing and updating the firmware in the terminal device through the air interface. The operating system and system configuration of the device can be updated through the OTA upgrade. [0003] At present, the OTA upgrade is mainly through the network (such as Wi-Fi, 4G) to automatically download the OTA upgrade package for upgrade. However, in the existing technology, due to the lack o...
