Problems solved by technology

[0003] However, since the server needs to encrypt and decrypt the firmware during the upgrade process, the original firmware of the terminal device can be obtained. Therefore, malicious attackers can steal the original firmware of the terminal device through the server, resulting in poor security for OTA upgrades.

Embodiment Construction

[0030] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, but not to limit the present disclosure.

[0031] In the following description, words such as "first" and "second" are only used for the purpose of distinguishing descriptions, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or implying order.

[0032] First, the application scenarios of the present disclosure will be described. OTA upgrade is a software upgrade method. Whether it is an Android smart terminal or an iOS smart terminal, it has an OTA upgrade function. Through this function, it is possible to detect online whether the device manufacturer has a new system that can be upgraded, and through the wireless network or terminal equipment. ...

Abstract

The invention relates to an over-the-air technology upgrading method and device, a storage medium and terminal equipment, and the method is applied to the terminal equipment and comprises the steps that encrypted differential firmware corresponding to the terminal equipment is acquired from a server, and the encrypted differential firmware comprises one or more encrypted differential data; and for each piece of encrypted differential data in the one or more pieces of encrypted differential data, decrypting the encrypted differential data to obtain decrypted differential data, obtaining current data corresponding to the decrypted differential data from the current version firmware, decrypting the current data to obtain current decrypted data, and sending the current decrypted data to the current version firmware. According to the decrypted differential data and the current decrypted data, generating to-be-upgraded data corresponding to the terminal equipment, and storing the to-be-upgraded data in the terminal equipment; and forming the firmware of the version to be upgraded by the generated one or more pieces of data to be upgraded. In this way, the original firmware can be prevented from being stolen by hostile attackers, and therefore the OTA upgrading safety is improved.

Description

technical field [0001] The present disclosure relates to the field of terminal technologies, and in particular, to an over-the-air technology upgrading method, device, storage medium and terminal device. Background technique [0002] Over-the-Air Technology (OTA) upgrade is mainly to automatically download the OTA upgrade package through the network for upgrade. In the related technology, the encrypted version firmware can be stored in the server. When the terminal device needs to be upgraded, it can be updated to the server. After sending an acquisition instruction, the server can decrypt the encrypted version firmware, generate new firmware according to the decrypted firmware and the firmware currently used by the terminal device, and send the new firmware to the terminal device so that the terminal device can Upgrade the system according to this new firmware. [0003] However, since the server needs to encrypt and decrypt the firmware during the upgrade process, the orig...
