A kind of OTA security upgrading system and upgrading method thereof

Abstract

The invention relates to an OTA security upgrade system and an upgrade method thereof, which belong to the technical field of communication, and in particular relate to a system and a method for OTA security upgrade. Including the OTA platform upgrade method and the OTA terminal upgrade method; the OTA platform upgrade method includes security upgrade management, security version management, version download management and security control; The upgrade provides corresponding upgrade version file key acquisition and processing, upgrade pre-condition judgment and pre-order operation, security key request management and upgrade process status detection rules functions, and the OTA terminal integrates the upgrade operation management of multiple intelligent parts. Through standardized equipment upgrade process management, OTA security upgrades of multiple types of intelligent components can be realized for large-scale equipment integrators, meeting the privacy and security requirements of various intelligent component upgrades, and effectively improving the security and stability of upgrades .

Description

technical field [0001] An OTA security upgrade system and an upgrade method thereof of the present invention belong to the technical field of communications, and in particular relate to an OTA security upgrade system and method. Background technique [0002] The full name of OTA is Over-The-Air technology (over-the-air technology), which realizes remote management of software through the interface of mobile communication. At present, with the continuous development of OTA technology, it has been widely used in industries such as automobiles, construction machinery, and mobile communications. [0003] The current OTA upgrade method is: the terminal device initiates a software version detection, and the server returns a version download path to the terminal device, so that the terminal device obtains an upgrade package according to the download path, and then performs version upgrade according to the upgrade package. During the OTA upgrade process, the version is generally se...

AI Technical Summary

Problems solved by technology

[0004] 1. The whole machine platform has weak security control for different types of components and equipment, equipment upgrades are mainly completed by the terminal, the platform lacks control over the upgrade process and dependencies, and lacks the necessary real-time response to related abnormalities;

[0005] 2. The platform service provider tends to delegate all the work of updating the device version to the terminal, and the equipment provider and the platform service provider often have different concerns. The parts and equipment provider does not want to Upgrades to devices that have not been authenticated and authorized by themselves
