Abstract

The invention is applicable to the technical field of data security, and provides a firmware upgrading method, a device and a computer readable storage medium. The firmware upgrading method comprisesthe following steps: performing first signature verification on a firmware upgrading packet after first signature according to a preset public key; if the first signature passes the verification, decrypting the first encrypted firmware upgrade package based on a preset decryption algorithm and a decryption key to obtain a first firmware upgrade package; wherein the first firmware upgrade package is obtained by signing an original firmware upgrade package based on a preset private key; and if the second signature of the first firmware upgrade package passes the verification, obtaining an original firmware upgrade package from the first firmware upgrade package to perform firmware upgrade operation. According to the firmware upgrading method, before and after the first encrypted firmware upgrading package is decrypted, signature verification needs to be carried out on the firmware upgrading package, so that the security of the firmware upgrading package is improved, and the firmware canbe safely upgraded.

Description

technical field

[0001] The present application belongs to the technical field of data security, and in particular relates to a firmware upgrading method, device and computer-readable storage medium. Background technique

[0002] Firmware is the driver program stored inside the device. Through the firmware, the operating system can implement the operation of the corresponding machine (such as CD-ROM drive or burner, etc.) according to the standard device driver. In practical applications, because the device often encounters some unpredictable problems during operation, in order to solve these problems, it is usually necessary to configure the firmware upgrade package to upgrade the firmware of the device, and then solve various problems that occur during the operation of the device.

[0003] However, in the process of using the firmware upgrade package to upgrade the device firmware, since the firmware upgrade package is easily cracked maliciously, in the existing scheme, the...
