Terminal equipment upgrading method and device, computer equipment and storage medium

Abstract

The invention relates to a terminal equipment upgrading method and device, computer equipment and a storage medium. The method comprises the following steps: sending an access request instruction to an upgrade server, and receiving an authentication reply result fed back by the upgrade server based on the access request instruction; analyzing the authentication reply result to obtain identity authentication information, wherein the identity authentication information comprises access result information of the terminal equipment and randomly generated verification information; on the basis of the access result information obtained through analysis, when the request access is confirmed to be successful, generating a first token on the basis of the verification information; acquiring equipment information, transmitting the first token and the equipment information to an upgrading server, enabling the upgrading server to inquiring an upgrading data packet based on the equipment information according to the first token when determining that the terminal equipment has a downloading permission, and feeding back upgrading data packet downloading information to the terminal equipment when the inquiring is successful; and receiving upgrading data packet downloading information fed back by the upgrading server, and upgrading the equipment according to the upgrading data packet downloading information.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a terminal equipment upgrading method, device, computer equipment and storage medium. Background technique [0002] With the development of IoT technology, more and more IoT terminals are going online. However, after the application site is installed and connected to the network, relevant maintenance personnel also need to maintain and upgrade the IoT terminal according to customer needs or market changes, and because the number of general IoT terminals is relatively large and the installation locations are also different , so when manufacturers maintain and upgrade it, most of them upgrade equipment based on wireless upgrade technology. [0003] The existing wireless upgrade technology mainly downloads the program update package through the wireless network, and performs flash burning and upgrading through the downloaded program update package. Although the existin...

Problems solved by technology

Although the existing wireless upgrade technology can effectively upgrade the device, when the program update package is downloaded, the program update package may be intercepted maliciously, or the package may be dropped, which may cause an unknown source to be updated during the upgrade. The program update package cannot guarantee the security of device upgrades, and there are certain security risks
