Abstract

The invention discloses a firmware upgrading method of equipment. The equipment comprises a security chip which stores a decryption secret key. The firmware upgrading method includes following steps:adopting an encryption secret key to encrypt an original firmware upgrading packet to acquire an encrypted firmware upgrading packet; sending the encrypted firmware upgrading packet to the equipment to enable the security chip to adopt the decryption secret key to decrypt the encrypted firmware upgrading packet to acquire the original firmware upgrading packet to complete firmware upgrading operation. The invention further discloses the equipment and a firmware upgrading device thereof. Transmission safety of the firmware upgrading packet of the equipment is improved, so that safety in remotefirmware upgrading of the equipment is improved.

Description

technical field [0001] The present invention relates to the technical field of equipment, in particular to a device firmware upgrade device, a device and a firmware upgrade method thereof. Background technique [0002] The firmware is a driver stored inside the device, that is, the firmware is an indispensable part of the operating system of the device. When the device is running, there may be problems such as inexplicable errors, frequent crashes, automatic restarts, black screens, and white screens. At this time, the firmware of the device needs to be upgraded to solve such problems. [0003] In the prior art, when the firmware upgrade package is transmitted to the device, the attacker can monitor the firmware upgrade package in the transmission process, so as to destroy the firmware upgrade package, so that the device receives the malicious firmware upgrade package, resulting in the failure of the firmware upgrade of the device , causing the device to be paralyzed, that ...
