Abstract

The invention provides a firmware upgrading method and device, electronic equipment and a storage medium, and the firmware upgrading method comprises the steps: receiving a state reporting request transmitted by terminal equipment, enabling the state reporting request to employ a signature encryption mode, verifying the identity of the equipment through the decryption of the state reporting request, issuing an upgrading URL after the identity verification is completed, wherein the upgrade URL is also issued in an encrypted form; receiving a firmware downloading request sent by the equipment, wherein the firmware downloading request comprises a firmware downloading range; reading a firmware upgrade package fragment corresponding to the firmware downloading range; and encrypting the firmwareupgrade package fragment and sending the encrypted firmware upgrade package fragment to the terminal equipment, so as to enable the terminal equipment to upgrade the function of the firmware corresponding to the firmware downloading range according to the firmware upgrade package fragment, repeating the steps, and finishing upgrading after the terminal equipment stores all the upgrade package fragments.

Description

technical field [0001] The present application relates to the technical field of firmware upgrade, and in particular, to a firmware upgrade method, device, electronic equipment and storage medium. Background technique [0002] The Internet of Things platform supports device firmware upgrades through the air download technology (OTA). Usually, the OTA cloud platform (server) is required to create a firmware upgrade task, and then the terminal device reports its own firmware version, and the cloud sends the upgrade firmware package URL, and the device downloads the firmware. Prepare to upgrade, report the result after the download is successful, and finally install the upgrade package on the device. However, there is no security guarantee for the upgrade package production and transmission in the existing OTA upgrade process, so that the upgrade package may be stolen or tampered with, and there is a problem of low security. . Contents of the invention [0003] The purpose o...
