OTA security upgrading system and upgrading method thereof

Abstract

The invention belongs to the technical field of communication, and particularly relates to an OTA security upgrading system and method. The OTA platform upgrading method comprises an OTA platform upgrading method and an OTA terminal upgrading method. The OTA platform upgrading method comprises security upgrading management, security version management, version downloading management and security control. The OTA terminal upgrading method is matched with an OTA platform function. Corresponding upgrade version file secret key acquisition and processing, upgrade precondition judgment and preorderoperation, safety secret key request management and upgrade process state detection rule functions are provided for upgrading of each intelligent part device, and the OTA terminal integrates and manages upgrade operation of a plurality of intelligent parts. Through standardized equipment upgrading process management, OTA safety upgrading of multiple types of intelligent parts is achieved for a large complete equipment integration party, the requirements for privacy and safety of upgrading of various intelligent parts are met, and the upgrading safety and stability are effectively improved.

Description

Technical field [0001] The invention provides an OTA security upgrade system and an upgrade method thereof, belonging to the field of communication technology, and in particular relates to an OTA security upgrade system and method. Background technique [0002] The full name of OTA is Over-The-Air technology (over-the-air download 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 a version upgrade according to the upgrade package. In the OTA upgrade process, the version is generally...

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
